PHP extensions may be installed in a variety of ways.
PECL is a repository of PHP extensions
living within the PEAR structure, and
the following demonstrates how to install these extensions.
These instructions assume /your/phpsrcdir/ is the path
to the PHP source, and extname is the name of the
PECL extension. Adjust accordingly. These instructions also assume a
familiarity with the pear command.
Shared extensions may be installed by including them inside of php.ini
using the extension PHP directive. See
also the extensions_dir
directive, and dl(). The installation methods described
below do not automatically configure PHP to include these extensions, this
step must be done manually.
When building PHP modules, it's important to have the appropriate versions
of the required tools (autoconf, automake, libtool, etc.) See the
Anonymous CVS Instructions for
details on the required tools, and required versions.
