How to Change PHP Version on DirectAdmin Hosting

Choosing the right PHP version on DirectAdmin hosting is critical for websites running WordPress, Joomla, Laravel, or any PHP-based application. Different PHP versions offer varying levels of performance, security, and compatibility.

This guide walks you through changing PHP version on DirectAdmin step by step, compares available versions, and answers common questions.

Supported PHP Versions on DirectAdmin

Hosting environments using DirectAdmin typically support multiple PHP versions simultaneously through MultiPHP or PHP Selector, allowing users to choose the version they need without affecting other accounts.

AsiaGB Hosting supports the following PHP versions:

• PHP 7.4 (Legacy — End of Life, not recommended)
• PHP 8.0 (End of Life)
• PHP 8.1 (Security Support)
• PHP 8.2 (Active Support — recommended)
• PHP 8.3 (Latest — most recommended)

Why Upgrade Your PHP Version?

There are several compelling reasons to upgrade your PHP version:

• Security: Older PHP versions no longer receive security patches, leaving your site vulnerable to attacks
• Performance: PHP 8.x is significantly faster than PHP 7.x, reducing server load and page load times
• Compatibility: Modern plugins, themes, and frameworks require PHP 8.x
• JIT Compiler: PHP 8.0+ includes JIT compilation for CPU-intensive tasks
• New Features: Named Arguments, Match Expressions, Fibers, and more enable cleaner, more efficient code

How to Check Your Current PHP Version

Before making changes, verify your current PHP version using one of these methods:

Method 1: Through DirectAdmin Panel

1. Log in to your DirectAdmin panel
2. Navigate to Extra Features → PHP Selector or Select PHP Version
3. Your current PHP version will be displayed

Method 2: Create a phpinfo.php file

Create a file named phpinfo.php in your public_html folder with this content:

<?php phpinfo(); ?>

Open https://yourdomain.com/phpinfo.php in your browser to see complete PHP configuration. Always delete this file immediately after use.

Step-by-Step: Changing PHP Version in DirectAdmin

Follow these steps to change your PHP version in DirectAdmin:

1. Log in to DirectAdmin
   Open your browser and go to your DirectAdmin URL, such as https://ns1.yourdomain.com:2222. Log in with your hosting username and password.
2. Go to Extra Features
   On the DirectAdmin dashboard, find the Extra Features or Advanced Features section.
3. Click PHP Selector or Select PHP Version
   You'll see a list of available PHP versions (e.g., PHP 7.4, 8.0, 8.1, 8.2, 8.3).
4. Select Your Desired PHP Version
   Click on the version you want. Some interfaces also let you enable or disable specific PHP extensions.
5. Click Apply or Save Changes
   Save your settings. The change takes effect within 1–2 seconds.
6. Verify the Change
   Refresh your phpinfo.php page to confirm the PHP version has been updated.

Setting PHP Version via .htaccess

You can also control PHP version through .htaccess, which is useful for specific directories:

# Set PHP 8.2 via .htaccess (depends on your hosting setup)
AddHandler application/x-httpd-php82 .php

Setting Different PHP Versions Per Domain

If you host multiple domains in one account, you can set a different PHP version for each domain:

1. Log in to DirectAdmin → go to Domain Setup
2. Select the domain you want to configure
3. Look for PHP Version or PHP Mode options
4. Select the desired PHP version for that domain → Save

This allows one domain running a legacy application (PHP 7.4) and another with a modern app (PHP 8.3) to coexist in the same account without conflict.
