Imagine you are given a server and you are asked to change its PHP settings. Also, assume that several different versions of PHP are installed on this server. What do you think is the best way to find a PHP configuration file? You will find the answer to this question below.

Method 1 (phpinfo file): #

One way to find out exactly which php.ini file your web sever is using is by creating a new PHP file in document root called info.php

<?php
phpinfo();
?>

Load this file in your browser, press CTRL + F and search for “Loaded Configuration File”. You should see something like.

This will tell you the exact location of the php.ini file you want to edit.

Method 2 (PHP.ini & grep command) #

In Linux, run this command to locate the PHP.ini configuration file.

 $ php -i | grep "Loaded Configuration File" 

Or better way:

 $ php -i | grep ini 

Or in Windows Command Line:

 $ php -i | findstr /c:"Loaded Configuration File"

 $ Loaded Configuration File => /etc/php/7.4/cli/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 site 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 settings, please do so through the MultiPHP INI Editor.

To modify the PHP settings:

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

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 at 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. In the Files section of your cPanel, click on the File Manager icon.
   

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

4. In the pop-up box, enter php.ini in the New File Name field. Make sure the root directory is in the bottom box.
   

5. Click Create New File.
6. Locate and right-click the new php.ini file and select Edit, then click the Edit button again.
7. You can now input the contents of your php.ini file. Click Save to save your changes.
