What is php.ini?


The php.ini file is a special file for PHP. It is where you declare changes to your PHP settings. The server is already configured with standard settings for PHP, which your website will use by default. Unless you need to change one or more settings, there is no need to create or modify a php.ini file. If you would like to make any changes to the settings, you can do so through the MultiPHP INI Editor.

This article will discuss the following topics.

How to modify PHP settings

via the MultiPHP INI Editor

There may be times when you need to change some of the default PHP settings, and below we've outlined those steps. However, keep in mind that there are PHP settings that cannot be changed on our Shared, Cloud, and Reseller hosting plans.

To modify the PHP settings:

  1. Log in to cPanel.
  2. In the Software section, click on the MultiPHP INI Editor icon.

    cPanel - MultiPHP INI Editor

  3. On the MultiPHP INI Editor page, select Home Directory or the specific domain you wish to update from the Configure PHP INI basic settings dropdown.

How to create a new php.ini file

Important Note: HostGator won't know why you want or need to change these settings. You would change this on the advice of your web designer or the developer of your script. HostGator can only show you where to make the change.
  • For Plesk users, the file should already exist in the directory  /var/www/vhost/$DOMAIN/etc/php.ini.
  • For the cPanel, this file should be created in your Home directory (/home/username/).

The username is your actual cPanel username, and $DOMAIN is your actual domain.

To create a new php.ini file in your cPanel:

  1. Log in to your cPanel.
  2. Under the Files section, click on the File Manager icon.

    cPanel - File Manager

  3. Select the root directory for your site. The default for the primary domain is public_html.
  4. Click the + File button at the top left of the page.
