Install xdebug with laravel in vscode ubuntu 20.04 with different version of php

Different php version has different xdebug.

follow xdebug installtion step according to php version setuped in your machine

php7.4 -v
php -v

this will return the php version, if xdebug is configured it will show , if not let's install it

let's install xdebug

sudo apt install php7.4-xdebug
sudo apt install php-xdebug

php7.4 --ini
php --ini

look for

/etc/php/7.4/mods-available/xdebug.ini
/etc/php/8.0/mods-available/xdebug.ini

and add this to /etc/php/7.4/mods-available/xdebug.ini

; zend_extension=xdebug.so
zend_extension=/usr/lib/php/20190902/xdebug.so
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.client_port = 9003

and add this to /etc/php/8.0/mods-available/xdebug.ini
for php8.0

; zend_extension=xdebug.so
zend_extension=/usr/lib/php/20200930/xdebug.so
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.client_port = 9003

now type in

php7.4 -v
php -v

you should see xdebug string returned in output

Note if you are confused about which php version is needed for which xdebug

to check which xdebug.so files are available use locate, if locate not availbe use this cmd to install it

sudo apt install mlocate
locate xdebug.so
simply paste the details you recieved from
