🔹 PHP Version & Settings #

PHP is the programming language behind most websites, including WordPress. Managing the correct PHP version and extensions ensures your website runs fast and securely.

1️⃣ Changing PHP Version #

Different websites may require different PHP versions. Using an outdated version can cause errors or security issues.

Steps in Plesk:

1. Log in to Plesk → Websites & Domains

2. Click PHP Settings

3. Select the desired PHP version from the dropdown

4. Click Apply

📌 Always test your website after changing PHP versions.

2️⃣ Using CloudLinux PHP Selector #

CloudLinux allows you to choose PHP versions per domain without affecting other accounts on the server.

Benefits:

• Multiple PHP versions available simultaneously

• Isolated environment for each domain

• Improve compatibility with older scripts or plugins

Steps:

1. Log in to Plesk → PHP Selector

2. Select domain

3. Choose PHP version and execution mode (e.g., CGI, FastCGI)

4. Save changes

📌 FastCGI mode is recommended for WordPress and performance optimization.

3️⃣ Enabling PHP Extensions #

Some scripts or plugins require additional PHP extensions (e.g., GD, cURL, mbstring).

Steps in Plesk / CloudLinux:

1. Go to PHP Selector → Extensions

2. Tick required extensions (e.g., GD, cURL, ZIP, mbstring)

3. Save changes

📌 Only enable necessary extensions to reduce security risks.

🔐 Tips for PHP Management #

• Use the latest stable PHP version for security

• Test plugins/themes after PHP version change

• Disable unused PHP extensions

• For critical sites, back up before making changes
