[SOLVED] Failed loading Xdebug PHP 7.4.0

I am trying to use Xdebug for coverage and debugging in PhpStorm. I have followed several tutorials, mainly this one.

I am getting this error when running php -v.

Failed loading C:\php\ext\php_xdebug-3.1.6-7.4-vc15-x86_64.dll
PHP 7.4.0 (cli) (built: Nov 27 2019 10:14:18) ( ZTS Visual C++ 2017 x64 )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies

Environment:

I downloaded the dll file from here. Specifically

Xdebug 3.1.6
Release date: 2022-11-08
PHP 7.4 VC15 TS (64 bit)

Because I have the Thread Safe version.

This is the result of php -i

At the end of it I added these lines:

[xdebug]
zend_extension="C:\php\ext\php_xdebug-3.1.6-7.4-vc15-x86_64.dll"
xdebug.mode=debug
xdebug.client_host=127.0.0.1
xdebug.client_port="9003"

Which are meant to configure the zend extension.

I am trying to solve this issue, I already tried different Xdebug versions TS, NTS, x64 and x32 (even when I think I need the TS and x64 one).

My expected result is to have the extension working.

Solution

As Derick suggested in this question, you need at least PHP 7.4.20 or PHP 8.0.7. I downloaded php-7.4.20-Win32-vc15-x64.zip and it works like a charm!
