Configure Xdebug + PHPstorm on wsl2

First of all we need wsl2 ip address. To find out what’s the ip open windows powershell and run ipconfig
Under the Ethernet adapter vEthernet (WSL) look for the IPv4 Address

Go to wsl2 and open your php.ini
e.g sudo nano /etc/php/7.x/apache2/php.ini
And paste these configurations

zend_extension=”xdebug.so”
xdebug.remote_enable=1
xdebug.remote_autostart=1
xdebug.client_host=paste-wsl-ip-address
xdebug.client_port=9001
xdebug.mode=debug,develop,profile
xdebug.cli_color=1
xdebug.start_with_request=trigger
xdebug.log_level=3
xdebug.idekey=PHPSTORM
xdebug.discover_client_host=false
xdebug.max_nesting_level=256
xdebug.log = /var/www/html/xdebug.log
xdebug.profiler_enable=On

Note: These settings works for xdebug 3. If you are on xdebug 2 then use xdebug.remote_host and xdebug.remote_port instead

And restart your webserver
