When you are running a PHP file from command line, there may be times when you need to make changes to the PHP settings. In this guide we will show you how to specify the php.ini file, and change a PHP setting in command line. If you are not working in command line, you can change your PHP settings in cPanel.

(For developers or sysadmins experienced with the command line, get High Availability and Root Access for your application, service, and websites with Cloud VPS Hosting).

Specify the php.ini File in Command Line

  1. Connect to your server using SSH.
  2. You can specify the php.ini file in command line by using the following syntax:

    php -c [Path to php.ini file] [Path to .php file]

    For example:

    php -c /home/userna5/public_html/php.ini /home/userna5/public_html/example.php

    Now the example.php file will run, with the limitations set in the php.ini file located here: /home/userna5/public_html

Change PHP settings

  1. Connect to your server using SSH.
  2. You can specify php.ini settings in command line with this syntax:

    php -c [Path to php.ini file] [Path to .php file] -d [PHP setting]

    For example:

    php -c /home/userna5/public_html/php.ini /home/userna5/public_html/example.php -d memory_limit=256M

    In this example, you can see I am setting the memory limit to 256 Megabytes. Here are some other PHP settings that are often modified:

Congratulations, now you know how to set the php.ini file, and change your PHP settings from command line!

You can comment out a line in the php.ini from the command prompt by using a text editor such as nano or vim. I have included a link to a guide on how to use nano below.

Hello kp,

Thank you for contacting us. You must specify the path to the .php file, or the command will not know what to run.

Thank you,
