Pensé unpocomásen esto y dadoeltamaño de labase de código de WP (incluidas lasbibliotecasincluidas),noparecemuy realista compilar dicha lista amano (y repetirlapara cadanueva versión,meh).

Busqué la herramienta de análisis de códigoestático adecuada: PHP_CompatInfo y después de algunos retoquesgeneradosel siguienteinforme deextensiones utilizadasporelnúcleo (versiónescaneada 3.3.1):

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).

La respuestaparaestopuede ser complicada ymuy larga,hasta donde yo sé,también habrá algunas diferenciasentre servidores & amp; SO (IIS,Apache) .. Nopuedo decir que la siguiente lista sea una lista COMPLETA,peroincluye algunos de los que sé que son obligatorios:

• Curl y CurlSSL :noestoy seguro de que sea REQUERIDO ,perogranparte del código de WordPress lo usará siestá disponible. Sinembargo,muchos complementos SÍ lo requieren y/otendránfunciones limitadas sin él.

• Exif :permite al administrador demedios de WordPressextraer datos Exif sinimágenes.

• Gettext : .po .mogestiona lainternacionalización de la localización detraducciones.

• FTP : se utilizapara realizar actualizaciones deplugins y WordPress através de FTP.

• GD - Nonecesitapresentación,¿verdad?

• Iconv : conversiones de conjuntos de caracteresparatodo,desde correo hasta análisis RSS.

• Mbregex y Mbstring -elnombreesbastante descriptivo -proporcionanfunciones que se utilizanen todaspartes :-)

• Mcrypt :noesnecesariopara wordpress,peromuchos complementos sí lonecesitan.

• Mime Magic : obsoleto ahoraen wordpress,pero aúnesbuenotener compatibilidad con versiones anteriores.

• * Mysql y Mysql del sistema * :todos sabemos quéesesto ypor quéesnecesario,¿no?

• Openssl :estabiblioteca se usaparamanejar conexiones deprocesamiento cifrado con certificados SSLpara WordPresspuede conectarse a cualquier ubicación cifrada SSL (https).

• POSIX : se utilizaparagarantizar que WordPressmantiene correctamente lospermisos y lapropiedad de los archivos.

• Verificación deinformación de ruta : algunas configuraciones deenlacespermanentes.

• Pspell : capacidades de revisión ortográficapara TinyMCE,.

• Sockets :gestión de conexiones FTP ygestión de correotambién conocido como SMTP y POPen WordPress.

• Zip :noestoy seguro de sies REQUERIDO,peroesta clase deextracción y creación de archivos zip compatiblemultiplataforma será utilizadapor wordpress siestá disponible.

• Zlib : se utilizaen muchos casos.ejemplo: compresión de archivosjs y css. denuevo,noestoy seguro si REQUERIDO peronecesario.

Como seindicó anteriormente,estanoes deningunamanera una lista COMPLETA. Se compiló hace aproximadamente un año yesposible quenecesite alguna actualización. Muchas deesasfuncionesno sonexactamente REQUERIDAS sino RECOMENDADAS . Enmuchos casos,wordpress usará unafunción siestá disponible,y sino,ignorará latarea. Unbuenejemploes lafalta debiblioteca GD,no detendráelfuncionamiento de wordpress,perono recortará,redimensionaráni alterará lasimágenes cargadas,dejando asíel original (yen gris la opción "tamaño"en el "insertarimagenparapublicar "función) ..

Comonota almargen,también diría quetal vezestapreguntaprobablemente obtenga respuestasmás correctas/actualizadasen serverfault.com que aquí ...

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 ...

( Estonopretende ser una respuesta. Soloinformación útil. Si cree queestainformaciónnoes útil,avíseme,simplemente laeliminaré).

Creo que hablaren términos de paquetes seríamásfácilpara losnovatos,pero dado que lospaquetes varían de un sistema a otro,es difícil abarcarlostodos.

Comotengoexperiencia con Debian (y distribucionesbasadasen Debian),me gustaría compartirestainformaciónespecífica:

• php5-cli
• php5-dev
• php5-fpm
• php5-cgi
• php5-mysql
• php5-xmlrpc
• php5-curl
• php5-gd
• php-apc (noes obligatorio,pero se recomienda)
• php-pear
• php5-imap
• php5-mcrypt
• php5-pspell

Lospaquetes antesmencionadosinstalantodas lasextensiones/bibliotecas/módulosmencionadosen las otras respuestas; todos,excepto Mime Magic,que yanoesnecesariopara WordPress .

Otrabuenaforma de asegurarse de que su servidor sea 100% compatible con WordPresses comprobar con quépaquetes vienenpreinstalados las empresas de alojamiento administrado . Comotienen años deexperiencia con quejas de clientes sobreincompatibilidades,lo sabránmejor.

Enel caso de Hostgator ,losmódulos PHP quepreinstalanincluyen (usted Probablemente solonecesite lamayoría peronotodos):

Media Templeproporciona un phpinfo(); para que compruebes su configuración. Tambiénes útilparafines de comparación.

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.

Si desea unaforma sencilla de verificar si su servidor cumple conestos requisitos,ahora hay un útil comandoext de WP-CLI para hacerlo.

wp ext requiredmuestratodas lasextensiones de PHP necesarias paraejecutar WordPress,mientras que wp ext recommendedmuestra las opcionales . wp ext checkes una combinación de ambos comandos.

Estos son útiles cuandonecesita unaforma rápida de verificar los requisitos del sistemaen unnuevo servidor y/o si desea seguirprocesandoesta listamedianteprogramación.

Asíes comofunciona 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
+-----------+-----------+

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

• curl: realiza operaciones de solicitud remota.
• exif:funciona conmetadatos almacenadosen imágenes.
• filtro: se utilizaparafiltrar deforma segura laentrada del usuario.

• libsodium:generabytes aleatorios.
• openssl:permite conexionesbasadasen SSL a otros hosts.
• pcre: aumentael rendimiento de la coincidencia depatronesen lasbúsquedas de código.
• imagick:proporciona unamejor calidad deimagenpara las cargas demedios. ¡Vea que WP_Image_Editorestáentrando!para detalles. Cambio detamaño deimagenmásinteligente (para imágenesmáspequeñas) y compatibilidad conminiaturas PDF,cuando Ghost Scripttambién disponible.
• xml: se utilizaparael análisis de XML,como desde un sitio deterceros.

Tambiénenumera las siguientesextensiones PHP como opcionales:

• gd: si Imagicknoestáinstalado,labiblioteca degráficos GD se utiliza como un respaldofuncionalmente limitadopara lamanipulación deimágenes.
• mcrypt:generabytes aleatorios cuando libsodiumnoestá disponible.
• xmlreader: se utilizaparael análisis de XML.
• zlib: compresión y descompresión 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.

Heestadoejecutando WP con laextensiónnativamysqlndpor untiempo,esbastantebueno.Tieneelementos de reflexiónintegrados,por lo que si desea ver quéestá sucediendo con labase de datosen esa solicitudespecífica,puede hacerlo.

zip comoextensiónnoesnecesario,lamayoría de losprogramas llaman alejecutable zip del 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.

Oficialmente, WordPress.org dice que solo se requieren las siguientesextensiones de PHP apartir de WP Core 5.3+ y cuando se usa la versión recomendada de PHP,que actualmentees 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.
 

...perotambién recomiendan las siguientesextensiones opcionales:

 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.
 

Sinembargo,tengaen cuenta que algunas deestasextensiones obligatorias (u opcionales) yaestánincluidasen otrospaquetes PHP. Porejemplo,dom amenudo seincluyeen laextensión xml. Y otros como fileinfoprobablemente yaesténinstalados comoparte de unpaquete llamado php-common siestá utilizando Ubuntu,etc.

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:

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.

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.
