Install a PHP extension manually

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.
