You need to have root access to your server to be able to edit this file, which usually means it needs to be dedicated or a VPS. If you are on a shared server you will not be able to find or edit it.
Normally it is under /usr/local/lib/php.ini SSH to your server and run: locate php.ini For most purposes you want to make changes in a .htaccess file. This way a site specific change doesn't affect the whole server. If you do need to change something globally in php, edit it in the file.
Hi Bigmodo, Create a page name phpinfo.php and insert the below code into it. Open this page up in your browser. <?php // Show all information, defaults to INFO_ALL phpinfo(); // Show just the module information. // phpinfo(8) yields identical results. // phpinfo(INFO_MODULES); ?> PHP: Hum NepaliSongs.TV
