Xdebug configuration with Vim

Question

I am on Ubuntu 20.04 using php 7.4.18 and apache and has its document root at /var/www/html . This is my php --version

PHP 7.4.18 (cli) (built: May  3 2021 11:27:06) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.18, Copyright (c), by Zend Technologies
    with Xdebug v3.0.3, Copyright (c) 2002-2021, by Derick Rethans

my xdebug.ini

zend_extension=xdebug.so
xdebug.remote_autostart = 1
xdebug.remote_enable = 1
xdebug.remote_handler = dbgp
xdebug.remote_host = 127.0.0.1
xdebug.remote_mode = req
xdebug.remote_port = 9000

My.vimrc

let g:vdebug_options = {"port": 9000, "break-on-open": 0, }

I have a wordpress installation in /var/www/html/wordress and when i try to debug in vim it is showing "Vdebug will wait for a connection" even if i access "localhost/wordpress" with ?XDEBUG_SESSION_START=1 ( I tried installing Xdebug Helper for chrome ) it is not connecting.

What other things i have tried

1. I added the xdebug.ini code to php.ini but couldn't get it connected.
2. Added "path_maps": {'/':'/var/www/html'} to vdebut_option in vimrc.

Please help and let me know what am i doing wrong?

This is my xdebug_info() screenshot

Answer 1

You're setting Xdebug 2 settings, but running Xdebug 3:

xdebug.remote_autostart = 1
xdebug.remote_enable = 1
xdebug.remote_handler = dbgp
xdebug.remote_host = 127.0.0.1
xdebug.remote_mode = req
xdebug.remote_port = 9000

You need to convert these to Xdebug 3 settings, as per the upgrade guide . The xdebug_info() output that you shared has links to the "Docs" (most right column) too, and it shows that "Step Debugger" is not enabled.
