Installing PHP modules<\/h1>\n

The default installation of PHP as described in\u00a0Installing PHP<\/span>\u00a0<\/a>will install the following PHP modules:<\/p>\n

\n
\n
[root@websrv ~]# <\/span>php -m\r\n[PHP Modules]<\/span>\r\nbz2<\/span>\r\ncalendar<\/span>\r\nCore<\/span>\r\nctype<\/span>\r\ncurl<\/span>\r\ndate<\/span>\r\nereg<\/span>\r\nexif<\/span>\r\nfileinfo<\/span>\r\nfilter<\/span>\r\nftp<\/span>\r\ngettext<\/span>\r\ngmp<\/span>\r\nhash<\/span>\r\niconv<\/span>\r\njson<\/span>\r\nlibxml<\/span>\r\nmysql<\/span>\r\nmysqli<\/span>\r\nopenssl<\/span>\r\npcntl<\/span>\r\npcre<\/span>\r\nPDO<\/span>\r\npdo_mysql<\/span>\r\npdo_sqlite<\/span>\r\nPhar<\/span>\r\nreadline<\/span>\r\nReflection<\/span>\r\nsession<\/span>\r\nshmop<\/span>\r\nSimpleXML<\/span>\r\nsockets<\/span>\r\nSPL<\/span>\r\nsqlite3<\/span>\r\nstandard<\/span>\r\ntokenizer<\/span>\r\nxml<\/span>\r\nzip<\/span>\r\nzlib<\/span>\r\n<\/pre>\n<\/div>\n<\/div>\n
That\u2019s quite a lot of modules, thanks to\u00a0php-common<\/span><\/code>, but different websites often need different modules installing, and there are a couple of ways to install them.<\/p>\n
\n
Package manager method<\/h2>\n
In the below example, we\u2019ll install the\u00a0SOAP<\/span><\/code>\u00a0extension using the systems default package manager,\u00a0yum<\/span><\/code>.<\/p>\n
After using\u00a0php<\/span>\u00a0-m<\/span><\/code>\u00a0as above, we can see that\u00a0SOAP<\/span><\/code>\u00a0is not in the list.<\/p>\n
To install, use the following command:<\/p>\n
\n
\n
yum install php-soap<\/span>\r\n<\/pre>\n<\/div>\n<\/div>\n
The format of that command could be changed to install different modules<\/a>, so you could install\u00a0imap<\/span><\/code>\u00a0or\u00a0snmp<\/span><\/code>\u00a0with the following commands:<\/p>\n
\n
\n
yum install php-imap<\/span>\r\n<\/pre>\n<\/div>\n<\/div>\n
\n
\n
yum install php-snmp<\/span>\r\n<\/pre>\n<\/div>\n<\/div>\n
After you\u2019ve accepted this, the install will run and you can re-run\u00a0php<\/span>\u00a0-m<\/span><\/code>\u00a0to confirm that the module is now in the list.<\/p>\n
A restart of your web server will be needed to load this new module in before your web server can access it:<\/p>\n
\n
\n
service httpd restart<\/span>\r\n<\/pre>\n<\/div>\n<\/div>\n<\/section>\n
\n
PECL<\/h2>\n
Some modules may not be available in your standard repositories, but fear not. As long as you have the\u00a0php-pear<\/span><\/code>\u00a0package installed, you\u2019ll have access to\u00a0pear<\/span><\/code>\u00a0and\u00a0pecl<\/span><\/code>, which are like package managers especially for PHP.<\/p>\n
In this example, we\u2019ll be installing the Memcached module for PHP.<\/p>\n
The command to start it all off is:<\/p>\n
\n
\n
pecl install memcache<\/span>\r\n<\/pre>\n<\/div>\n<\/div>\n
\n
\n
\n
Using pecl will often need you to install a few dependencies.<\/p>\n
Which ones will depend on what\u2019s installed on your system already, but in the above example on a CentOS minimal install, I had to install\u00a0gcc<\/span><\/code>,\u00a0make<\/span><\/code>\u00a0and\u00a0zlib-devel<\/span><\/code><\/p>\n<\/div>\n<\/div>\n<\/blockquote>\n
PECL installs often ask a few questions during the install process. If you\u2019re not too sure what to put, hitting enter will accept the default value.<\/p>\n
Once this has finished, you\u2019ll have to tell PHP where it can find it\u2019s new module, as the text on complete will tell you.<\/p>\n
In the Memcached example, the following line needs to be added to your PHP configuration:<\/p>\n
\n
\n
extension=memcache.so<\/span>\r\n<\/pre>\n<\/div>\n<\/div>\n
This could just be added to the bottom of\u00a0\/etc\/php.ini<\/span><\/code>, but to keep things neat I opted to put it in the following file:<\/p>\n
\n
\n
\/etc\/php.d\/memcache.ini<\/span>\r\n<\/pre>\n<\/div>\n<\/div>\n
The file likely won\u2019t exist, and you can call it what you want as long as it ends in\u00a0.ini<\/span><\/code><\/p>\n
After you\u2019ve done this, the install will run and you can re-run\u00a0php<\/span>\u00a0-m<\/span><\/code>\u00a0to confirm that the module is now in the list.<\/p>\n
A restart of your webserver will be needed to load this new module in before your webserver can access it:<\/p>\n
\n
