Quali sono le estensioni e le librerie PHP di cui ha bisogno e / o utilizza WP?

Ci hopensato ancorae data la dimensione del codice WP (comprese le libreriein bundle)non sembramolto realistico compilaretaleelenco amano (e ripeterloper ogninuova versione -meh).

Ho cercato uno strumento di analisi del codice statico appropriato - PHP_CompatInfo e dopo alcuni ritocchigeneratiin seguito al rapporto sulleestensioni utilizzate dal core (versione sottoposta a scansione 3.3.1):

• cURL - 127 utilizzi (richiede libcurl )

  • API HTTP (classe WP_Http_curl)
  • url_is_accessable_via_ssl()
  • SimplePie (sovrascritto con la classe WP_SimplePie_File)
  • GoogleSpell (dalpacchetto TinyMCE,non viene utilizzato?)

• Data/ora - 367 utilizzi

• DOM - 6 utilizzi (richiede libxml )

  • iis7_rewrite_rule_exists()
  • iis7_delete_rewrite_rule()
  • iis7_add_rewrite_rule()
  • saveDomDocument()

• POSIX Regex - 23 utilizzi

• Filtro - 2 usi

  • class PHPMailer->ValidateAddress() (opzionale)

• FTP - 72 utilizzi

  • class ftp_base
  • class ftp (versioni pure e socket )
  • class WP_Filesystem_FTPext
  • class WP_Filesystem_ftpsockets

• GD - 56 utilizzi

  • wp-admin\includes\image-edit.php
  • wp-admin\includes\image.php
  • wp-includes\media.php

• Hash - 6 utilizzi

  • wp-includes\pluggable.php usimultipli (opzionale -fallbackin wp-includes\compat.php)

• iconv - 5 utilizzi

  • class SimplePie (opzionale)
  • wp_check_invalid_utf8() (opzionale)
  • wp-mail.php (opzionale)

• JSON - 20 utilizzi

  • facoltativo,fallbackin wp-includes/compat.php

• libxml - 4 usi

  • class WP_oEmbed->_parse_xml() (opzionale)
  • SimplePie

• Multibyte String - 29 utilizzi

  • alcunifallbackin wp-includes/compat.php

• MySQL - 60 utilizzi

  • class wpdb
  • class SimplePie_Cache (sovrascritta con la classe WP_Feed_Cache)

• OpenSSL - 4 utilizzi

  • classe PHPMailer

• PCRE - 743 utilizzi

• SimpleXML - 1 utilizzi

  • class WP_oEmbed (sembra opzionale)

• Socket - 64 utilizzi

  • class ftp (implementazione di sockets)

• SPL - 3 usi

• Tokenizer - 3 usi

  • wp_doc_link_parse() (opzionale)

• XML Parser - 89 utilizzi

• XMLReader - 1 utilizzi

  • SimplePie (sembrafacoltativo)

• Zlib - 30 utilizzi

I gave this some more thought and given size of WP code base (including bundled libraries) it doesn't seem very realistic to compile such list by hand (and repeat it for every new version - meh).

I looked up appropriate static code analysis tool - PHP_CompatInfo and after some tinkering generated following report of extensions used by core (version scanned 3.3.1):

• cURL - 127 uses (requires libcurl)

  • HTTP API (class WP_Http_curl)
  • url_is_accessable_via_ssl()
  • SimplePie (overridden with class WP_SimplePie_File)
  • GoogleSpell (from TinyMCE package, is not used?)

• Date/Time - 367 uses

• DOM - 6 uses (requires libxml)

  • iis7_rewrite_rule_exists()
  • iis7_delete_rewrite_rule()
  • iis7_add_rewrite_rule()
  • saveDomDocument()

• POSIX Regex - 23 uses

• Filter - 2 uses

  • class PHPMailer->ValidateAddress() (optional)

• FTP - 72 uses

  • class ftp_base
  • class ftp (pure and sockets versions)
  • class WP_Filesystem_FTPext
  • class WP_Filesystem_ftpsockets

• iconv - 5 uses

  • class SimplePie (optional)
  • wp_check_invalid_utf8() (optional)
  • wp-mail.php (optional)

• JSON - 20 uses

  • optional, fallbacks in wp-includes/compat.php

• libxml - 4 uses

  • class WP_oEmbed->_parse_xml() (optional)
  • SimplePie

La rispostapotrebbeessere complicatae molto lunga,per quantone so,ci saranno anche alcune differenzetrai server & amp; OS (IIS,Apache) .. Nonposso dire cheil seguenteelenco sia unelenco COMPLETO,mainclude alcuni di quelli che so che sononecessari:

• Curle CurlSSL :non sono sicuro che sia OBBLIGATORIO ,magranparte del codice WordPress lo utilizzerà se disponibile. Tuttavia,moltiplugin LO richiedono e/o avrannofunzioni limitate senza diesso.

• Exif : consente algestoremultimediale di WordPress diestrarrei dati Exif senzaimmagini.

• Gettext - .po .mogestisce l'internazionalizzazione della localizzazione dellatraduzione ..

• FTP : utilizzatopereseguiregli aggiornamenti diplugine WordPresstramite FTP.

• GD - Non c'èbisogno dipresentazioni,giusto?.

• Iconv : conversioni di set di caratteripertutto,dallaposta all'analisi RSS.

• Mbregexe Mbstring -ilnome èpiuttosto descrittivo -fornisconofunzioni usate ovunque :-)

• Mcrypt :nonnecessarioper wordpress,mamoltipluginne hannobisogno.

• Mime Magic : ora deprecatoin wordpress,ma è ancora utileper la compatibilità con le versioniprecedenti.

• * Mysqle Mysql del sistema * - sappiamotutti cos'èe perché ènecessario,no?

• Openssl : questa libreria viene utilizzatapergestire le connessioni dielaborazione crittografato con certificati SSLper WordPresspotrebbeesserein grado di connettersi a qualsiasiposizione crittografata SSL (https).

• POSIX : utilizzatopergarantire che WordPressmantenga correttamentei permessie leproprietà deifile.

• Controlloinformazionipercorso : alcune configurazioni dipermalink.

• Pspell :funzionalità di controllo ortograficoper TinyMCE,.

• Socket :gestione delle connessioni FTPe gestione dellaposta AKA SMTPe POPin WordPress.

• Zip - Non sono sicuro se NECESSARIO,ma questa classe di creazioneedestrazione difile zip compatibilemultipiattaforma VERRÀ utilizzata da wordpress,se disponibile.

• Zlib : utilizzatoin molti casi.esempio: compressione difilejse css. dinuovo,non sono sicuro se RICHIESTO manecessario.

Come sopra affermato - questonon è affatto unelenco COMPLETO - È stato compilato circa un annofa -e potrebbe richiedere qualche aggiornamento. Molte di questefunzioninon sonoesattamente RICHIESTE ma CONSIGLIATE . Inmolti casi wordpress utilizzerà unafunzione SE è disponibilee,in caso contrario,ignorerà l'attività. Unbuonesempio è lamancanza della libreria GD,chenonimpedirà a wordpress difunzionare,manon ritaglierà,ridimensionerà o altererà leimmagini caricate,lasciando così l'originale (e disattivando l'opzione "size"in "inserisciimmagine dapostare "funzione) ..

Comenota amargine,vorrei anche dire cheforse questa domandaprobabilmente otterrà rispostepiù corrette/aggiornate su serverfault.com che qui ...

The answer for this might be complicated and very long, as far as I know, there will also be some differences between servers & OS (IIS, Apache).. I can not say that the following list is a FULL list, but it includes some of those I know that are required :

• Curl and CurlSSL – Not sure it is REQUIRED but but much of the WordPress code will use it if it is available. Many plugins however DO require it and/or will have limited functions without it.

• Exif – allows media handler of WordPress to pull Exif data out of images.

• Gettext - .po .mo handling translation localization internationalization ..

• FTP – used to do plugin and WordPress upgrades via FTP.

• GD – No need introduction, right ?.

• Iconv – character set conversions for everything from mail to RSS parsing.

• Mbregex and Mbstring – the name is pretty descriptive - provide functions used all over the place :-)

• Mcrypt – Not needed for wordpress, but many plugins do need it.

• Mime Magic – Deprecated now in wordpress - but still good to have for back compatibility.

• *Mysql and Mysql of the system *– we all know what this is and why it is needed, no ?

• Openssl – This library is used to handle processing connections encrypted with SSL certificates for WordPress may to be able to connect to any SSL (https) encrypted location.

• POSIX – used to ensure that WordPress properly maintains file permissions and ownerships .

• Path Info Check – some permalink setups .

• Pspell – spell checking capabilities to TinyMCE, .

• Sockets – managing FTP connections and mail handling AKA SMTP and POP in WordPress.

• Zip – Not sure if REQUIRED - but this cross-platform compatible zip file creation and extraction class WILL be used by wordpress if available.

• Zlib – Used in many cases . example - js and css files compression. again, not sure if REQUIRED but needed.

Like Above stated - this is by no means a FULL list - It was compiled about a year ago - and it might need some update . Many of those functions are not exactly REQUIRED but ADVISED. In many cases wordpress will use a function IF it is available, and if not , will ignore the task. A good example is the lack of GD library, it will not stop wordpress from functioning, but it will not crop, resize , or alter the uploaded images - thus leaving the original (and grey- out the "size" option in the "insert image to post" function)..

As a side note - I would also say that maybe this question will probably get more correct/updated answers on serverfault.com than here ...

( Questanon vuoleessere una risposta. Solo alcuneinformazioni utili. Se ritieni che questainformazionenon sia utile,fammelo sapere,la cancellerò semplicemente.)

Penso cheparlarein termini di pacchetti sarebbepiùfacileperi neofiti,mapoichéi pacchetti variano da sistema a sistema,è difficile coprirlitutti.

Dato che hoesperienza con Debian (& amp; distribuzionibasate su Debian),vorrei condividere questeinformazioni specifiche:

• php5-cli
• php5-dev
• php5-fpm
• php5-cgi
• php5-mysql
• php5-xmlrpc
• php5-curl
• php5-gd
• php-apc (non richiesto,ma consigliato)
• php-pear
• php5-imap
• php5-mcrypt
• php5-pspell

I suddettipacchettiinstallanotutte leestensioni/librerie/modulimenzionatinelle altre risposte; tutti,tranne Mime Magic,che non èpiù richiesto da WordPress .

Un altrobuonmodoper assicurarti cheiltuo server sia compatibile al 100% con WordPress è controllare con qualipacchetti sonopreinstallate le società di hostinggestito . Poiché hanno anni diesperienza coni reclami dei clienti sulleincompatibilità,ne sapranno dipiù.

In caso di Hostgator ,i moduli PHP chepreinstallanoincludono (tuprobabilmente serviranno solo lamaggiorparte manontutti):

Media Templefornisce un phpinfo(); per controllare la loro configurazione. È utile anche a scopo di confronto.

The aforementioned packages install all the extensions/libraries/modules mentioned in the other answers; all, except Mime Magic, which is no longer required by WordPress.

Another good way to make sure your server is 100% compatible with WordPress is to check what packages the managed hosting companies come pre-installed with. As they have years of experience with customer complaints about incompatibilities, they'll know better.

In case of Hostgator, the PHP modules they pre-install include (you'll probably only need most but not all of them):

Media Temple provides a phpinfo(); file for you to check their config. It's useful for comparison purposes too.

Se desideri unmodo sempliceper verificare seiltuo server soddisfa questi requisiti,ora è disponibile unpratico comando WP-CLIext perfarlo.

wp ext requiredmostratutte leestensioni PHP necessarie pereseguire WordPress,mentre wp ext recommendedmostra quelle facoltative . wp ext check è una combinazione dientrambii comandi.

Sono utili quando ènecessario unmodo rapidoper verificarei requisiti di sistema su unnuovo servere/o se si desideraelaborare ulteriormente questoelenco a livello diprogrammazione.

Ecco comefunziona wp ext required:

 $ wp ext required

+-----------+-----------+
Success: All required extensions are installed
 

If you want an easy way to verify if your server meets these requirements, there's now a handy WP-CLI ext command to do so.

wp ext required shows all PHP extensions necessary to run WordPress, while wp ext recommended shows optional ones. wp ext check is a combination of both commands.

These come in handy when you need a quick way to check the system requirements on a new server and/or if you want to further process this list programmatically.

Here's how wp ext required works:

$ wp ext required
+-----------+-----------+
| extension | installed |
+-----------+-----------+
| curl      | 1         |
| date      | 1         |

Se stai usando Debian 7 (Debian Wheezy),deviinstallare PHP stessoe unpiccolonumero diestensioni. Lamaggiorparte di ciò che è statomenzionato da @Rarst ègiàinclusoin una delleinstallazioni PHPpiùbasilari di Debian.

<"PHP

Sono disponibili quattro opzioniin Debian Wheezy: libapache2-mod-php5 , libapache2-mod-php5filter ,php5-cgi o php5-fpm . Scelgophp5-fpmmatutto dipende da come vuoi cheiltuo server webe PHPinteragiscano.

<"MySQL

Hai anchebisogno di PHPper usare MySQL. Letue opzioni sono php5-mysql e php5-mysqlnd .php5-mysqlnd ènativoe generalmentepiù veloce. Alcunipotrebbero scegliere un'alternativa come MariaDB.

Libreriagrafica Facoltativa

Se desideri ridimensionare letueimmagini,puoiinstallare php5-gd o < a href="https://packages.debian.org/wheezy/php5-imagick" rel="nofollow">php5-imagick .php5-imagickti darà una qualitàmiglioree Wordpress lo userà se disponibile. Se sonoinstallatientrambi,verrà utilizzatophp5-imagick. Senessuno dei due èinstallato,leimmagininon verranno ridimensionate (e Wordpressnon si lamenterà).

HTTP Facoltativo

Seinstalli php5-curl ,verrà utilizzatomanon richiestoper qualsiasi cosatranneforseprestazionimigliori.

Nient'altro è richiesto da Wordpresse dallamaggiorparte delleestensioni,sebbene alcuneestensionipossano avere altri requisiti.

Ecco la linea completa diinstallazione dibaseper dare a Wordpresstutto ciò di cui habisognoperprestazioni ottimalie niente dimeno:

 apt-get install php5-fpm php5-mysqlnd php5-imagick php5-curl
 

If you're using Debian 7 (Debian Wheezy), you need to install PHP itself and a small number of extensions. Most of what was mentioned by @Rarst is already included with one of Debian's most basic PHP installs.

PHP

You have four options in Debian Wheezy: libapache2-mod-php5, libapache2-mod-php5filter, php5-cgi, or php5-fpm. I choose php5-fpm but it all depends on how you want your web server and PHP to interact.

MySQL

You also need PHP to use MySQL. Your options are php5-mysql and php5-mysqlnd. php5-mysqlnd is native and generally faster. Some might choose an alternative like MariaDB.

Graphics Library Optional

If you want your images resized, you may install either php5-gd or php5-imagick. php5-imagick will give you better quality and Wordpress will use it if it's available. If both are installed, php5-imagick will be used. If neither is installed, images will not be resized (and Wordpress won't complain).

HTTP Optional

If you install php5-curl, it will be used but is not required for anything except perhaps better performance.

Nothing else is required by Wordpress and most extensions, though some extensions may have other requirements.

Here is the complete basic install line to give Wordpress everything it needs for optimal performance and nothing it doesn't:

apt-get install php5-fpm php5-mysqlnd php5-imagick php5-curl

Il manuale di WordPress oraelencailmoduli PHP consigliati:

Il core di WordPress utilizza leestensioni PHP. Se l'estensionepreferita manca WordPress o dovràfarepiù lavoroper svolgere l'attività ilmodulo aiuta con o,nelpeggiore dei casi,rimuoverà funzionalità. Pertanto leestensioni PHPelencate di seguito sono consigliato.

• bcmath: utilizzatopermigliorare leprestazioni dei calcolimatematici.
• curl:esegue operazioni di richiesta remota.
• exif:funziona coni metadati archiviatinelleimmagini.
• filtro: utilizzatoperfiltrarein modo sicuro l'input dell'utente.
• fileinfo: utilizzatoper rilevareiltipo MIME dei caricamenti difile
• mod_xml: utilizzatoper lagenerazione di XML,adesempioper unamappa del sito XML. Nota chemod_xml è unmodulo Apache,non un'estensione PHP,ma èelencato per consapevolezza.
• mysqli - Si collega a MySQLper leinterazioni conil database.
• libsodium:generabyte casuali.
• openssl: consente le connessionibasate su SSL ad altri host.
• pcre - Aumenta leprestazioni della corrispondenza deimodellinelle ricerche di codice.
• imagick:fornisce unamigliore qualità dell'immagineperi caricamentimultimediali. Vedi WP_Image_Editor èin arrivo!per dettagli. Ridimensionamento delleimmaginipiùintelligente (per immaginipiùpiccole)e supportoperminiature PDF,quando anche Ghost Script disponibile.
• xml: utilizzatoper l'analisi XML,adesempio da un sito diterzeparti.

Elenca anche le seguentiestensioni PHP comefacoltative:

• gd - Se Imagicknon èinstallato,la libreriagrafica GD viene utilizzata come riservafunzionalmente limitataper lamanipolazione delleimmagini.
• mcrypt:generabyte casuali quando libsodiumnon è disponibile.
• xmlreader: utilizzatoper l'analisi XML.
• zlib: compressionee decompressione Gzip.

The WordPress handbook now lists the recommended PHP modules:

WordPress core makes use of PHP extensions. If the preferred extension is missing WordPress will either have to do more work to do the task the module helps with or, in the worst case, will remove functionality. Therefore the PHP extensions listed below are recommended.

• bcmath – Used to improve the performance of math calculations.
• curl – Performs remote request operations.
• exif – Works with metadata stored in images.
• filter – Used for securely filtering user input.
• fileinfo – Used to detect mimetype of file uploads
• mod_xml – Used for generating XML, such as for an XML sitemap. Note that mod_xml is an Apache module, not a PHP extension, but is listed for awareness.
• mysqli – Connects to MySQL for database interactions.
• libsodium – Generates random bytes.
• openssl – Permits SSL-based connections to other hosts.
• pcre – Increases performance of pattern matching in code searches.
• imagick – Provides better image quality for media uploads. See WP_Image_Editor is incoming! for details. Smarter image resizing (for smaller images) and PDF thumbnail support, when Ghost Script is also available.
• xml – Used for XML parsing, such as from a third-party site.

It also lists the following PHP extensions as being optional:

• gd – If Imagick isn’t installed, the GD Graphics Library is used as a functionally limited fallback for image manipulation.
• mcrypt – Generates random bytes when libsodium isn’t available.
• xmlreader – Used for XML parsing.
• zlib – Gzip compression and decompression.

It's worth mentioning that since WordPress 5.2, there is a built in feature that reports on missing modules. Find it at Tools > Site Health.

haibisogno delleestensionimysqli,pdoe gd.etalvolta xml-rpc.

Eseguo WP con l'estensionenativamysqlnd da unpo 'ditempo,è abbastanza carino.Ha roba di riflessioneincorporata,quindi se vuoi vedere cosa sta succedendo conil dbin quella specifica richiesta,puoifarlo.

zip comeestensionenon ènecessaria,lamaggiorparte deiprogrammi chiama l'eseguibile zip di sistema.

you need the mysqli, pdo, and gd extensions. and sometimes xml-rpc.

I've been running WP with the mysqlnd native extension for a while now, it's pretty neat. Has reflection stuff built in, so if you want to see what's going on with the db in that specific request, you can do it.

zip as an extension is not needed, most programs call the system zip executable.

Ufficialmente, WordPress.org dice che solo le seguentiestensioni PHP sono richieste apartire da WP Core 5.3+e quando si utilizza la versione consigliata di PHP,che attualmente è PHP 7.2:

 curl -- Performs remote request operations.
dom -- Used to validate Text Widget content and to automatically configuring IIS7+.
exif -- Works with metadata stored in images.
fileinfo -- Used to detect mimetype of file uploads.
hash -- Used for hashing, including passwords and update packages.
json -- Used for communications with other servers.
mbstring -- Used to properly handle UTF8 text.
mysqli -- Connects to MySQL for database interactions.
libsodium -- Validates Signatures and provides securely random bytes.
openssl -- Permits SSL-based connections to other hosts.
pcre -- Increases performance of pattern matching in code searches.
imagick -- Provides better image quality for media uploads. See WP_Image_Editor is incoming! for details. Smarter image resizing (for smaller images) and PDF thumbnail support, when Ghost Script is also available.
xml -- Used for XML parsing, such as from a third-party site.
zip -- Used for decompressing Plugins, Themes, and WordPress update packages.
 

...ma consigliano anche le seguentiestensioni opzionali:

 filter -- Used for securely filtering user input.
gd -- If Imagick isn’t installed, the GD Graphics Library is used as a functionally 
limited fallback for image manipulation.
iconv -- Used to convert between character sets.
mcrypt -- Generates random bytes when libsodium and /dev/urandom aren’t available.
simplexml -- Used for XML parsing.
xmlreader -- Used for XML parsing.
zlib -- Gzip compression and decompression.
 

Tienipresente,tuttavia,che alcune di questeestensioni obbligatorie (ofacoltative) sonogià raggruppatein altripacchetti PHP. Adesempio,dom è spessoinclusonell'estensione xml. E altri come fileinfo sonoprobabilmentegiàinstallati comeparte di un cosiddettopacchetto php-common se stai usando Ubuntu,ecc.

Inoltre,ci sono alcune altreestensioni come bcmath chenon sono ufficialmente richieste o consigliate da WordPressma sono ancora utilizzate damoltipluginpopolari,come Yoast SEO.

Officially, WordPress.org says that only the following PHP extensions are required as of WP Core 5.3+ and when using the recommended version of PHP, which is currently PHP 7.2:

curl -- Performs remote request operations.
dom -- Used to validate Text Widget content and to automatically configuring IIS7+.
exif -- Works with metadata stored in images.
fileinfo -- Used to detect mimetype of file uploads.
hash -- Used for hashing, including passwords and update packages.

mbstring -- Used to properly handle UTF8 text.

libsodium -- Validates Signatures and provides securely random bytes.
openssl -- Permits SSL-based connections to other hosts.
pcre -- Increases performance of pattern matching in code searches.
imagick -- Provides better image quality for media uploads. See WP_Image_Editor is incoming! for details. Smarter image resizing (for smaller images) and PDF thumbnail support, when Ghost Script is also available.
xml -- Used for XML parsing, such as from a third-party site.
zip -- Used for decompressing Plugins, Themes, and WordPress update packages.

...but they also recommend the following optional extensions:

filter -- Used for securely filtering user input.
gd -- If Imagick isn’t installed, the GD Graphics Library is used as a functionally 
limited fallback for image manipulation.
iconv -- Used to convert between character sets.
mcrypt -- Generates random bytes when libsodium and /dev/urandom aren’t available.
simplexml -- Used for XML parsing.
xmlreader -- Used for XML parsing.
zlib -- Gzip compression and decompression.

Keep in mind, however, that some of these required (or optional) extensions are already bundled into other PHP packages. For example, dom is often included in the xml extension. And others like fileinfo are probably already installed as part of a so-called php-common package if you are using Ubuntu, etc.

In addition, there are a few other extensions such as bcmath that are not officially required or recommended by WordPress but are still used by many popular plugins, like Yoast SEO.
