How to edit php.ini file in cPanel ?

Your server’s administrator can customize these PHP configuration settings. The system displays them for your reference only.
If you or someone you know has access to WHM (the cPanel owner's panel), they might be able to. Otherwise it's a hack via terminal and that voids the warranty, if you know what I mean.
Keep in mind: some ini settings can be altered at runtime via ini_set().
Finally, you should really try and figure out how to post a new thread instead of hijacking this one. Look for a button that says, "Start a Discussion" ... which is, as you might guess, green.
