Adding a new PHP version number to the Eclipse IDE is a very useful feature that can help developers use different versions of PHP at the same time in the same development environment and facilitate switching. The following will introduce how to add a new PHP version number in Eclipse, with specific code examples.

Step 1: Download the required PHP version

First, you need to make sure you have downloaded the required PHP version. You can download the corresponding PHP version from the official website (http://www.php.net/downloads.php) and extract it to a local directory.
