PhpStorm is not receiving xdebug connections : PhpStorm event log : Cannot evaluate expression 'isset($_SERVER['PHP_IDE_CONFIG'])'
Solution 1
I had the exact same error in PhpStorm as the OP.
This answer to a different question solved the problem for me, but I would like to add more detail in my own answer.
The main issue was improperly loaded xdebug. The server mapping issues mentioned in other answers was not an issue for me.
If you load your phpinfo()
page and find the xdebug section, and you see this:
XDEBUG NOT LOADED AS ZEND EXTENSION
Then you have to fix that before you try anything else! But sometimes this can take some work to track down, if you have multiple php.ini
files.
Also in your phpinfo()
page, search for "php.ini", (it should be right near the top) and see your "Configuration File (php.ini) Path", and your "Loaded Configuration File". Those are where your xdebug may be loading.
In my case, I correctly loaded it as a Zend extension in my main configuration file in /usr/local/lib/php.ini, like so:
zend_extension = "/usr/local/lib/php/extensions/no-debug-non-zts-20121212/xdebug.so"
But in my Loaded Configuration file in /home/someuser/public_html/php.ini, I had it incorrectly loaded like this:
extension=xdebug.so
After fixing that, remote debugging with PhpStorm is working again for me.
As a side note, the first error I saw in PhpStorm was the exact same one the OP mentions, and here is what it looks like:
Cannot accept external Xdebug connection
Cannot evaluate expression 'isset($_SERVER['PHP_IDE_CONFIG'])'
( At first I thought that, because the extension was not loaded properly, PhpStorm was not able to execute PHP code on the server. But now I think PhpStorm only executes php code if you configured an interpreter, which isn't necessary for debugging. For debugging, PhpStorm just needs the xdebug connection and the correct path mappings.)
Later, I found the "Command is not available" error in the xdebug log on my server, which led me to the solution.
Here, by the way, is what I have in my local php.ini
for xdebug:
;extension=xdebug.so <- this is the bad line commented!
zend_extension = "/usr/local/lib/php/extensions/no-debug-non-zts-20121212/xdebug.so"
xdebug.remote_enable=true
xdebug.remote_port="9000"
xdebug.profiler_enable=1
xdebug.profiler_output_dir="/tmp/xdebug-someuser/"
xdebug.profile_enable_trigger=1
xdebug.trace_enable_trigger=1
xdebug.idekey="PHPSTORM"
xdebug.remote_log="var/log/xdebug/xlog"
Solution 2
I have recently had the same problem attempting to debug using PHPStorm
under nginx
and php-fpm
, in my case this was not related to the xdebug
, nginx
or php-fpm config
, it was the path mappings in phpstorm
that were missing.
Initially PHPStorm
will notify you when it cannot map a file on the server to a local source file however if it has a mapping to the first files hit ( normally index.php
or some such ) but it cannot map a file used at a later stage ( in my case this was the autoloader in the vendor directory of a project using composer ) then PHPStorm
will not be able to debug any further and debugging will stop.
In order to rectify this in PHPStorm
go to settings/Languages & Frameworks/PHP/Servers
and ensure the root of your project is mapped correctly to it's counterpart directory on the server.
PHPStorm
should then be able to map all the files in your project and debugging should continue.
I hope this helps.
Solution 3
Also same error if you missed to set environment variable in docker-compose.yml
for your workspace configuration:
workspace:
build:
environment:
- PHP_IDE_CONFIG=${PHP_IDE_CONFIG}
Solution 4
Debugging a file named «test.php» in IntelliJ IDEA / PhpStorm can lead to the «Cannot evaluate expression 'isset($_SERVER['PHP_IDE_CONFIG'])
'» failure.
Use another name for file.
Solution 5
For anyone else coming to this issue, there is another potential configuration option that you could be missing.
Make sure that you have correctly configured your server to use the correct path mapping between your local and remote files.
For example, if your site root is mounted locally at /home/foo/www/mysite
but installed on the server at /www/mysite
then you will need to edit your server configuration in PHPStorm to use path mappings (simply enter /www/mysite
in the box alongside /home/foo/www/mysite
).

I configured everything for PhpStorm and xdebug to work, I'm running Ubuntu 14.04.
the connection back to the IDE is not established, and I get this in the IDE event Log
Cannot accept external Xdebug connection: Cannot evaluate expression 'isset($_SERVER['PHP_IDE_CONFIG'])' – Osama Salama 13 mins ago
I'll put together configuration values I configured in various places. As I can't find out where is the problem
php.ini
zend_extension = /usr/lib/php5/20121212/xdebug.so xdebug.remote_enable=1 xdebug.remote_handler=dbgp xdebug.remote_mode=req xdebug.remote_host=127.0.0.1 xdebug.remote_port=9000 xdebug.remote_connect_back = 1 xdebug.remote_autostart = 1 xdebug.remote_log=xxx/xdebug.log xdebug.IDE_key=PHPSTORM

I also validated the remote debugging env. it's all good. https://www.jetbrains.com/phpstorm/help/validating-the-configuration-of-a-debugging-engine.html which also came out fine.
The last possible resort is the xdebug log file:

Guerrilla almost 9 yearsIt's making me do this for every single file individually, it won't let me just set mapping for the top level folder. Any ideas?
-
iainp999 almost 9 yearsHey - just set it at the root folder and all other files should be relative to that.

Osama Salama almost 9 yearsThanks Andrew, This is all true, and became my standard practice when working with new php projects, Cheers

Buttle Butkus about 8 yearsFor this, I would suggest using ssh tunneling. That way you keep your firewall in place and still can do the remote debugging. It will work even if you don't have access to the firewall/router settings. It was a bit tricky to set up though. You have to pay careful attention to the tutorials.

Shardj over 3 yearsI think I meant where's the value for ${PHP_IDE_CONFIG} supposed to come from however it's been two years so I can't be sure. Currently I have PHP_IDE_CONFIG="serverName=docker" set within my docker container to allow for cli debugging

MADforFUNandHappy over 3 years@DanielW. docker-compose can use the values from an .env file or you export the variable before you call docker-compose up
