hope you're doing great, I'm working on a Laravel project I didn't work on since a couple of months, and found that anytime an exception is raised, I get the following error:
[Fri Jan 15 15:51:11 2021] PHP Fatal error: Uncaught Error: Call to undefined function Whoops\Exception\xdebug_is_enabled() in /var/www/html/project/vendor/filp/whoops/src/Whoops/Exception/Inspector.php:254

Has anyone seen this error before and know a way to fix it? Thanks beforehand.
if you run any version of "filp/whoops" before 2.9, sudo pecl install -f xdebug-2.9.8 to install previous version as xdebug 3 onwards removed the function xdebug_is_enabled. https://xdebug.org/docs/upgrade_guide
Then add "zend_extension=/usr/lib/php/20190902/xdebug.so" to php.ini
"filp/whoops": "^2.9" should be able to support xdebug 3 as it check whether xdebug_is_enabled exists, as 2.9.1 is checking for the xdebug_is_enabled function https://github.com/filp/whoops/compare/2.9.0...2.9.1 https://github.com/filp/whoops/commit/dc30a4cb68b45a5fb65e190cf0a6b58d3d3ef096
If you already added zend_extension=/usr/lib/php/20190902/xdebug.so" to php.ini, please remove it before installing xdebug-2.9.8 as it will cause error in installation
Also dont just change the version of your package in composer.lock, it will not actually change the package version as the file download link is it in composer.lock as well.
turns out I was facing this issue and found out that just by updating "filp/whoops": "^2.0" to "filp/whoops": "^2.9" the problem was solved.
