Is it possible to change the location of php.ini to be used by Apache? When I did php -i | grep \'Configuration File\', the result is:
To Change php.ini file path we have to declare PHPINIDir in the apache configuration file 'httpd.conf' syntax for that is :
PHPINIDir "path_to_ini_file";
                                                                        PHP uses different .ini files when running via command line vs running as a web server module. When you grep the results of php -i your getting the command line ini. It's good practice to have separate ini's for the two environments.
If you must change the directory PHP looks for the php.ini file, you can use the PHPIniDir in your web server conf file.
If you wish to just add additional directories to be scanned, you can set the PHP_INI_SCAN_DIR environment variable.
