Xdebug Failed loading C:\php\ext\php_xdebug.dll

Question

Issue:

I am getting this error in my Apache log on start up:

Failed loading C:\php\ext\php_xdebug-2.9.2-7.4-vc15-x86_64.dll

Xdebug Wizard:

I used the xdebug wizard, which resulted in these instructions:

1. Download php_xdebug-2.9.2-7.4-vc15-x86_64.dll
2. Move the downloaded file to C:\php\ext
3. Edit C:\php\php.ini C:\WINDOWS\php.ini and add the line
4. zend_extension = C:\php\ext\php_xdebug-2.9.2-7.4-vc15-x86_64.dll
5. Restart the webserver

Things I have tried:

Using these variations in php.ini:

zend_extension="C:\php\ext\php_xdebug-2.9.2-7.4-vc15-x86_64.dll"

zend_extension=php_xdebug-2.9.2-7.4-vc15-x86_64.dll

I ensured I was editing correct php.ini file

I checked permissions on dll.

I am using:

• Apache/2.4.41 (Win64) VC 15

• php-7.4.3-Win32-vc15-x64

• php_xdebug-2.9.2-7.4-vc15-x86_64.dll

Answer 1

You're using a release candidate of PHP 7.4.1 (php-7.4.1RC1-Win32-vc15-x64) - you might want to use the latest PHP 7.4.3.

You sometimes get a better error message if you try using PHP's command line.
