The php.ini file also known as (configuration file) is where we declare changes for Php settings. If you want to use the default settings then you can use existing php.ini file for the server else change settings by editing the existing php.ini file or you can create a new text file and save it as php.ini .

NOTE: The configuration file (php.ini) is read when PHP starts up where else the server module versions of PHP, reads it only once when the web server is started.

Location of the php.ini file: The php.ini file should exist in your cPanel Home Directory i.e (/home/username/).
