Install a PHP extension manually

Note

This method is not applicable for installing PHP extensions in CloudLinux.

Native PHP version

Execute the command below to install an extension for the native PHP version:

yum install <package name>

apt install <package name>

Alternative PHP version

You can install an extension for the alternative PHP version:

• using the package manager Pecl;
• from the source code.

Install an extension using the package manager Pecl

Let's install memcache as an example:

1. Install the packages:

   CentOS

   yum install autoconf gcc zlib-devel

   BASH

   Debian

   apt install autoconf gcc zlib1g-dev

   BASH
   

   Note.

   Additional packages may be required when you install other extensions.

2. Install the extension:

   /opt/<PHP version directory>/bin/pecl install memcache

   BASH

3. Connect the extension for a required PHP version:

   echo extension=<extension library name> >> /opt/<PHP version directory>/etc/php.d/<extension name>.ini

   BASH

   For example:

   echo extension=memcache.so >> /opt/<PHP version directory>/etc/php.d/memcache.ini

   BASH

Install from the source code

Let's install env as an example::

1. Download and extract the archive with the extension source code:

   cd /tmp
   wget -O env.tar.gz http://pecl.php.net/get/env
   tar xzvf env.tar.gz
   cd env-0.2.1/

   BASH

2. Run the configuration and setup process:

   /opt/<version directory PHP>/bin/phpize
   ./configure --with-php-config=/opt/<PHP version directory>/bin/php-config && make && make install

   BASH

3. Enable the extension globally for the required PHP version:

   echo 'extension=env.so' > /opt/<PHP version directory>/etc/php.d/20-env.ini

   BASH

Note.

The extension setup process may require additional packages that are not described in this article.
