How can I debug a PHP CLI script with xdebug?
I haven't quite figured this out. EVERY piece of documentation I've found covers how to use xdebug to debug scripts running in Apache. I need to debug a php CLI script.
So, for instance, how do I pass the XDEBUG_SESSION_START variable in to get xdebug t开发者_开发问答o kick on?
I'm specifically trying to debug a CakePHP shell. So if anyone has any additional insight into that I'd be very appreciative.
Thanks.
There is a couple of notes about that in Xdebug's manual, like, for instance (quoting) :
export XDEBUG_CONFIG="idekey=session_name"
php myscript.php
If you are using Eclipse PDT to develop and debug your PHP scripts, there is not much difference between Apache or CLI : the configuration lloks quite the same, you just don't have to configure a web server, nor indicate an URL ; instead, you have to indicate the path to the PHP executable.
About the XDEBUG_SESSION_START
variable : well, you launch the whole script in "debug-mode", so you don't have any notion of "debugging-session", I'd say.
For instance, here's what Window > Preference > PHP > PHP executables
looks like for me right now, and, on the right, what I get when clicking on the Edit
button of the first one :

And the debug configurations
window :
(source: pascal-martin.fr)
And launching the debugging: it just works :

Hope this helps :-)
Else, what specific problem do you encounter ?
If you're using bash (or similar shell), this little script might come in handy:
alias drush-debug=drd
function drd {
export XDEBUG_CONFIG="idekey=cli_session"
export SERVER_NAME="developer.machine"
export SERVER_PORT="9000"
drush "$@"
unset XDEBUG_CONFIG
unset SERVER_NAME
unset SERVER_PORT
};
or as suggested by the commentators below
alias drd='XDEBUG_CONFIG="idekey=PHPSTORM" drush "$@"'
This way you don't have to manually set and unset the trigger variable each time you want to debug.
simply put the following section to your php.ini
[XDebug]
xdebug.max_nesting_level = 200
xdebug.remote_enable=1
xdebug.remote_port=9000
;xdebug.profiler_enable=1
xdebug.idekey=PHPSTORM
xdebug.remote_autostart=1
and replace PHPSTORM with your ide key
For Windows and Visual Studio Code here's how to proceed:
Download xdebug from https://xdebug.org/download. For example php 7.4 Windows 64bit https://xdebug.org/files/php_xdebug-2.9.5-7.4-vc15-nts-x86_64.dll
Copy the xdebug dll to your php extensions dir (ext).
Add to the end of php.ini
[XDebug]
zend_extension=php_xdebug-2.9.5-7.4-vc15-nts-x86_64.dll
xdebug.remote_enable=1
xdebug.remote_autostart=1
Open VSCode and install https://marketplace.visualstudio.com/items?itemName=felixfbecker.php-debug
Open the project workspace in VSCode, go to Run tab, click the cogwheel and add these lines
{
"name": "listen CLI",
"type": "php",
"request": "launch",
"port": 9000
},
{
"name": "run CLI",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}",
"port": 9000
}
Place a break point in the script you want to debug
Select "run CLI" and click "Start Debugging"
Happy debugging!
