Xdebug setup help

I'm having issues setting up Xdebug 2.7. Restarting Phpstorm 2019.1 does not show an Xdebug dialog. I'm on Lubuntu 18.04 with php 7.2.15 and Apache2. 

- Chrome debugger extension set to "debug" on target site for the project

- /etc/php/7.2/cli/php.ini is the config file being used in Phpstorm settings 

- port is set to 9000 in php.ini

Screenshots are given below:


Hi there,

Collect and provide Xdebug log for such unsuccessful debug session. It will have clues at what might be wrong.

As it stands right now: you are on Linux .. so quite high chances to have php-fpm installed as well. It uses the same TCP 9000 port as Xdebug ... so it's possible that Xdebug connects to php-fpm instead of IDE.


Is this the log you want?

owner@G700:~$ netstat -anp | grep CLOSE_WAIT
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 1 0 CLOSE_WAIT 3638/chrome --type=
tcp 1 0 CLOSE_WAIT 3638/chrome --type=
tcp 1 0 CLOSE_WAIT 2655/dropbox
tcp 32 0 CLOSE_WAIT 2655/dropbox
tcp 32 0 CLOSE_WAIT 2655/dropbox
tcp 32 0 CLOSE_WAIT 3638/chrome --type=
tcp 32 0 CLOSE_WAIT 2655/dropbox
tcp 32 0 CLOSE_WAIT 2655/dropbox


I have changed the port to 9004 in php.ini and phpstorm xdebug settings.


>Is this the log you want?


P.S. Just in case: make sure that you are editing the right php.ini file: on Linux it's very common to have one for CLI and different one used by Apache.


How do I switch the php.ini file being used by Phpstorm. You can see above that Phpstorm uses the one in the CLI directory


PhpStorm does NOT use any php.ini files. It simply reports whatever PHP Interpreter detects/uses. PHP Interpreter in PhpStorm is NOT used for executing web requests .. especially if you have Apache web server that serves your web pages.

Apache is different here. Run phpinfo() via web browser and see what php.ini it uses and edit that file.


phpinfo() points to: /etc/php/7.2/apache2/php.ini

But you can see in the 2nd image in my previous comment this is not the config file used by the interpreter in Phpstorm. The one Phpstorm uses is in the CLI folder. Which seems to be an issue.

I only have php 7.2.15 on my computer.


What are you trying to debug: a PHP script in CLI mode... or a web page?

If it's a web page then ignore PHP Interpreter altogether as it does not participate in web page debug and focus on settings from /etc/php/7.2/apache2/php.ini


in my config file at /etc/php/apache2/php.ini , I noticed the following settings were already present:

zend_extension = /usr/lib/php/20170718/xdebug.so


I added/changed:



Restarting Phpstorm I notice no changes, no dialog popup. Also, I do not see "xdebugRemoteLog" in the above php config file directory. I can not locate it using 'whereis' either.


I have noticed an Xdebug error pushed to the screen (for something that is a legitimate error, not revolving around Xdebug itself):

What exactly do you do to start a debugging session? Since it's Wordpress, I suppose you want to debug in the web mode. Just in case, please make sure you're doing everything in accordance to https://www.jetbrains.com/help/phpstorm/zero-configuration-debugging.html

Then, you have changed xdebug.remote_port to 9004. Did you reflect this change in PhpStorm at Settings | Languages & Frameworks | PHP | Debug?

And the Xdebug remote log still would be nice. Please note that you configured it wrong, xdebug.remote_log="xdebugRemoteLog" won't do anything. Please follow this guide to create and collect the Xdebug log: https://intellij-support.jetbrains.com/hc/en-us/articles/206544819-How-to-collect-remote-log-for-XDebug


I have the zero config debug setup. I installed the chrome debug extension and set it to "debug" on localhost. It now appears green on localhost


you have changed xdebug.remote_port to 9004. Did you reflect this change in PhpStorm at Settings | Languages & Frameworks | PHP | Debug?

I have yes


Then we definitely need to take a look at the Xdebug log. Please configure it and upload somewhere. Thank you!


Under what conditions will a debug file or entry get created? I do not see the folder or file being generated in the location specified in php.ini


It's created each time a debug session starts as long as the directory has write permissions for the user running the web server / interpreter.
Usually, it's easier just to create the file manually and set 777 permissions for it.
