How can PHP configuration affect the installation of PEAR?

PHP configuration can affect the installation of PEAR if the include_path is not properly set to include the PEAR directory. To solve this issue, you can update the php.ini file to include the path to the PEAR directory in the include_path directive. This will ensure that PHP can locate the PEAR files during installation.

// Update the include_path in php.ini to include the PEAR directory
ini_set('include_path', ini_get('include_path') . PATH_SEPARATOR . '/path/to/pear');
