How to change PHP version using PHPStudy?

PHPStudy is a free PHP development environment that can help you install and configure PHP, MySQL and other web services. But some users may find that they need to use different versions of PHP for development and testing. This article will detail how to use PHPStudy to change the PHP version.

Step 1: Download and install PHPStudy

If you have not installed PHPStudy, you can download and install it from the official website (http://www.phpstudy.net/). When installing PHPStudy, make sure to install it in the default path (C:\phpstudy). If you change the default installation path, subsequent steps may be incompatible.

Step 2: Select and download the PHP version you need

Before changing the PHP version, you need to determine which version you want to use. You can find all available versions on the official PHP website (http://php.net/downloads.php). Please note that even if you download the latest version of PHP, it may not be the version you need.

Download and unzip the PHP version. Rename the unzipped folder to its version number. For example, if you are using PHP version 7.2.31, rename the unzipped folder to php72131.

Step 3: Add PHP version in PHPStudy

Now, you need to add the newly downloaded PHP version to PHPStudy. Open the PHPStudy main interface, click the "Other" drop-down menu, and then click "PHP Version Manager".

In the PHP version manager, click the "Add" button. In the dialog box that appears, select the PHP version folder you just renamed and assign the version a version number. For example, if you are using PHP version 7.2.31, set its version number to 72131.

Click the "OK" button to add the new version to PHPStudy. You should see the name and version number of the new version in the PHP Version Manager.

Step 4: Switch the site to the new version of PHP

Now, you need to set the site you want to use to the new version of PHP. On the main PHPStudy interface, click Site Manager.

Select the site you want to change and click the "Settings" button behind it. In the site settings dialog box, select the "PHP Version" tab. Select the new version you just added and click the Save button.

Your site will now use the new version of PHP.

Summary

Use PHPStudy to easily switch PHP versions to facilitate your web development and testing. The process requires downloading and adding a new version of PHP, but once completed, you can easily switch between different PHP versions.
