Xdebug 3.0 with PHP 7.x

@cytopia, I've just downloaded devilbox/php-fpm:7.2-work-0.120 image and try to apply xdebug config from php 8.0
https://github.com/cytopia/devilbox/blob/v1.8.3/cfg/php-ini-8.0/devilbox-php.ini-xdebug

but i've noticed that some configuration settings are wrong, because I've xdebug v3 rather than v2

PHP 7.2.34 (cli) (built: Nov 18 2020 11:19:28) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.2.34, Copyright (c) 1999-2018, by Zend Technologies
    with Xdebug v3.0.1, Copyright (c) 2002-2020, by Derick Rethans

Config settings related to xdebug upgrade guide at https://xdebug.org/docs/upgrade_guide,
we should have by default

xdebug.mode               = debug
xdebug.start_with_request = yes
xdebug.client_port        = 9003
xdebug.idekey             = PHPSTORM
xdebug.log                = /var/log/php/xdebug.log

Notice that URL of upgrade guide have changed since v3 is now stable
see https://github.com/cytopia/devilbox/blob/v1.8.3/cfg/php-ini-8.0/devilbox-php.ini-xdebug#L24

Default configs for PHP 8.x must be updated :

• https://github.com/cytopia/devilbox/blob/v1.8.3/cfg/php-ini-8.0/devilbox-php.ini-xdebug
• https://github.com/cytopia/devilbox/blob/v1.8.3/cfg/php-ini-8.1/devilbox-php.ini-xdebug

I've also a recommandation: if we wan't use the new xdebug v3, de-activate it because it consume lot of time.

See upgrade guide https://xdebug.org/docs/upgrade_guide

Besides setting the mode with xdebug.mode, you can also set the mode with the XDEBUG_MODE environment variable. If this environment variable is active, it overrides the mode as set through xdebug.mode.

On command line

export XDEBUG_MODE=off

php your-script.php

I've a batch process that run in 6 secs when xdebug v3 is off and took 1 minute when xdebug is on !
