You can use the Pecl package manager or source code to install an alternative PHP version.

To install an alternative PHP version using the Pecl package manager (for example, for a memcache application):

1. Install packages (may require other packages depending on the extension):
   1. CentOS

      yum install autoconf gcc zlib-devel

   2. Debian

      apt install autoconf gcc zlib1g-dev

2. Install the extension:

   /opt/<PHP_version_directory>/bin/pecl install memcache

3. Connect the extension:

   echo extension=<extension_library_name> >> 
   /opt/<PHP_version_directory>/etc/php.d/<extension_name>.ini

To install an alternative PHP version using source code (for example, for the env extension):

1. Download and unzip the file with the source code of the required extension:

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

2. Run configuration and build:

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

3. Include the extension for the required PHP version:

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