How to change PHP version and update PHP extensions on Shared servers

In some cases, the correct functioning of your website depends on a PHP version installed on the server.
This guide describes how to change php version on Shared servers (Stellar, Stellar Plus plans and old Value, Professional, Ultimate plans). For Business SSD servers, use this guide.

Thanks to the PHP Selector function, it is possible to select the necessary PHP version as well as enable/disable certain PHP modules and functions.

To check what PHP version is currently in use, refer to this article.

Change PHP version and/or manage extensions

1. Log into your cPanel account.

2. Scroll down to the Exclusive for Namecheap Customers section >> Select PHP Version:

Also, the Select PHP Version menu can be located under the Software section on some servers:

3. Here you will see the list of available modules and extensions.

If you do not need to change the PHP version and just want to turn on/off specific extensions, you can do this by checking/unchecking the corresponding boxes.

Use the Current PHP version drop-down box to select the required version and click on Apply in order to apply the changes.

4. To change individual settings within the PHP version in question, click on the Options tab.

NOTE: If it is needed to set up the PHP version <5.6 for the account, please contact our Support Team.

By clicking on one of the options in blue, you will be presented with a drop-down list to change specific settings:

NOTE: In order to increase the max upload size, make sure to modify both post_max_size and upload_max_filesize values.

Sometimes your website may need to use a different PHP version from the one assigned to your whole cPanel account.

To set a different PHP version for an addon domain, you need to add a special code to your .htaccess file. To do this, follow the steps below.

1. Find the .htaccess file for the addon domain in question. The steps for how to find it can be located here.

2. For servers with LiteSpeed the code should be the following:

<FilesMatch ".(?:html|php)$">
SetHandler application/x-httpd-alt-phpXX

where XX is the PHP version you wish to set. It can be 52, 53, 54, 55, 56, 70, 71,72, 73, 74, 80, 81, 82 or 83.

For example:

3. Click Save changes.        

NOTE: When a different PHP version is set for the addon domain, there are no PHP extensions enabled by default. To make a website work correctly, you will need to upload a php.ini file to the folder of the addon domain. You can check this article to help you with uploading files to the hosting account.

You need to download the php.ini file for different PHP versions from the Attachments section at the end of this guide. Do not forget to rename the file to php.ini once it is uploaded to the hosting account.

Alternatively, you can run the command below via SSH:

cp /opt/alt/default_php_ini/phpXX.ini /home/cPanel_username/path_to_the_folder/php.ini

  • XX is PHP version you wish to set (it can be 52, 53, 54, 55, 56, 70, 71, 72, 73, 74, 80, 81, 82 or 83),
  • cPanel_username should be replaced with your actual cPanel username, and
  • path_to_the_folder is a path to the folder of the addon domain.

For example:

The process is similar if you wish to set a different PHP version for a subdomain.

That's it!
