Step 1: Check Existing PHP Extensions
To check the existing PHP extensions on your VPS, open a terminal and run the following command:

php -m

To check if a specific extension is installed, use the following command, replacing `extension_name` with the desired extension:

php -m | grep extension_name

For example, to check if the ctype extension is installed, run:

Step 2: Enable/Disable PHP Extensions via cPanel/WHM
You can enable or disable PHP extensions in cPanel/WHM by navigating to "WHM » Software » EasyApache 4 » Customize" in the "Currently Installed Packages" section.

Some PHP extensions are built into PHP and cannot be added or removed through EasyApache. To check if these extensions are present in your system, run the following command, replacing `extension_name` with the desired extension:
php -i | grep -E -i 'extension_name'

For example, to check if the JSON and OpenSSL extensions are installed, run:
php -i | grep -E -i '(json|openssl)'
