Downloading Xdebug

Download the compatible Xdebug library with your PHP version and install it as described in the installation guide.


The Windows binaries generally work for every mini release for the mentioned PHP version, although the extension is built against the most current PHP version at that time. The VCx/VSx marker tells with which compiler the extension was built, and Non-thread-safe whether ZTS was disabled. Those qualifiers need to match the PHP version you're using. If you don't know which one you need, please refer to the custom installation instructions.
