Xdebug doesn't show up as a module

Question

System:

OS Name Microsoft Windows 10 Pro
Version 10.0.19041 Build 19041

dll location and version:

C:\xampp\php\ext\php_xdebug-2.9.8-7.4-vc15-x86_64.dll

php.ini info:

C:\xampp\php\php.ini
[XDebug]
zend_extension = C:\xampp\php\ext\php_xdebug-2.9.8-7.4-vc15-x86_64.dll

phpinfo():

This program makes use of the Zend Scripting Language Engine: Zend
Engine v3.4.0, Copyright (c) Zend Technologies
    with Xdebug v2.9.8, Copyright (c) 2002-2020, by Derick Rethans

php -v output:

PHP 7.4.3 (cli) (built: Feb 18 2020 17:29:57) ( NTS Visual C++ 2017 x64 )  
Copyright (c) The PHP Group  
Zend Engine v3.4.0, Copyright (c) Zend Technologies

When I run php -m, the output is

[PHP Modules]
(a bunch of modules, but no xdebug)
[Zend Modules]
(empty)

Where do I go from here?

I would bet your php_xdebug-2.9.8-7.4-vc15-x86_64.dll is just not compatible with your PHP. Double check if you don't see anywhere something like Failed loading C:\xampp\php\ext\php_xdebug-2.9.8-7.4-vc15-x86_64.dll Also check if your edited php.ini is really used by your php binary.

In my Windows box I have zend_extension=php_xdebug-2.9.8-7.4-vc15-x86_64.dll in php.ini and PHP 7.4.10 (cli) ( ZTS Visual C++ 2017 x64 ) and it works like charm. Check NTS vs ZTS. Maybe you should use php_xdebug-2.9.8-7.4-vc15-nts-x86_64.dll
