How to upgrade xampp's php?

Generally speaking, it is not recommended to upgrade the PHP part of XAMPP separately. You should first consider upgrading the XAMPP server package.

Step 1:Back up important files

After XAMPP is installed, user data basically involves the following 3 places:

1. xampp/htdocs directory: This is the file system for all websites.

2. xampp/mysql/data directory: This is the database for all websites.

3. xampp/apache/conf/extra/httpd-vhosts.conf file: This is your virtual host (assuming you use a virtual host in XAMPP) configuration file.

You need to completely back up the above 3 directories/files. Finally, rename the old xampp folder to xampp_OLD or remove it.

Step 2:Uninstall the old xampp

If you want to uninstall the old xampp, select xampp/uninstall .exe.

Remove htdocs folder? If it has been backed up, select Yes, if there is no backup, select No.

Do you want to uninstall XAMPP and all its modules? Select Yes.

Step 3:Download and install the new xampp

Go to the official website to download the latest XAMPP installation package (exe format) , keep pressing Yes to continue. At this time, XAMPP can be installed in the xampp folder.

Step 4: Move the backup

Restore xampp/htdocs and xampp/mysql/data to the corresponding location in the new folder.

Done.
