I have a Docker container with xdebug in it, when I run the script I need to form the Docker container I receive from PhpStorm the following message:

Cannot parse server name for external Xdebug connection.
To fix it create environment variable PHP_IDE_CONFIG on the remote server.
Windows: set PHP_IDE_CONFIG="serverName=SomeName"
Linux / Mac OS X: export PHP_IDE_CONFIG="serverName=SomeName".

but I have already set those environment variables as you can see in the screenshot here:

xdebug.log

Here is the xdebug section from my phpinfo(): enter image description here enter image description here

And these are my settings for PhpStorm:

enter image description here

Environment from phpinfo():

enter image description here

PHP Variables from phpinfo():

enter image description here enter image description here enter image description here

I also tried to export env variables with and without quotes but the result was the same...

With quotes:

XDEBUG_CONFIG="remote_host=192.168.1.110"
PHP_IDE_CONFIG="serverName=docker-server"

Without quotes:

XDEBUG_CONFIG=remote_host=192.168.1.110
PHP_IDE_CONFIG=serverName=docker-server

The result from ifconfig en1 inet command from my MacOS where I'm running Docker and PhpStorm

You can also check the following files in cases needed:

Any help will be much appreciated!

Update:

Seems that if I add

environment:
  XDEBUG_CONFIG: "remote_host=192.168.1.110"
  PHP_IDE_CONFIG: "serverName=docker-server"

into my php service located inside docker-compose.yml it solves the issue but leaves me with a big question.

Since I have:

env_file:
  - ./etc/environment.yml
  - ./etc/environment.development.yml

and inside ./etc/environment.development.yml I have:

XDEBUG_CONFIG="remote_host=192.168.1.110"
PHP_IDE_CONFIG="serverName=docker-server"

And since it is not ignored and I can see that those Env variables are set even before I add environment property into my php service, why xdebug is only triggered when I have set the environment property? It feels like duplication for me to have it in both places and I prefer to have it inside ./etc/environment.development.yml rather than docker-compose.yml.

    1) Do you really have DBGp Proxy running on your computer? It's simply not needed especially for local Docker... You may have configured it .. but do you actually use it? have you actually installed it etc. Better not to touch it if you do not know how exactly it works. 2) What web server you are using? nginx I guess... If so -- try configuring the server name there 3) "I also tried to export env variables with and without quotes but the result was the same.." It has to be with. Commented May 3, 2018 at 13:21
  • 4) What the full phpinfo() output is? I'm after _SERVER / ENVIRONMENT parts only -- need to check if server name is visible there. 5) So far xdebug log says that it's connected to some IDE, most likely PhpStorm... so overall it's good .. just that part left. Commented May 3, 2018 at 13:21
  • What exactly do you mean if I really have DBGp proxy running? That is a setting inside PhpStorm and as far as I know, you need that in order to debug remote php servers. The reason I tried both with and without double quote is because of that bug. I'm familiar with remote debugging and I do it many times, but I now testing docker and want to switch over docker completely and while remote debugging works for me everywhere is not working with my docker instance.

  • @LazyOne I updated my original post to include Environment and PHP Variables section. Everything seems to be fine to me. The thing is that xdebug is connected to PhpStorm, but PhpStorm complains that "Cannot parse server name for external Xdebug connection." Commented May 3, 2018 at 17:17
  • 1) "What exactly do you mean if I really have DBGp proxy running? That is a setting inside PhpStorm and as far as I know, you need that in order to debug remote php servers." This means that you do not know how it works and when it's needed. Do not use it as you do not need it. See this if you wish to know when you may use it: confluence.jetbrains.com/display/PhpStorm/… Commented May 3, 2018 at 18:02

After some more digging,

I saw the following difference:

When I use env_file directive I had the following in my environment.development file:

XDEBUG_CONFIG="remote_host=192.168.1.110"
PHP_IDE_CONFIG="serverName=docker-server"

which resulted in: enter image description here

Notice the double quotes around the value.

When I was removing env_file directive and put the following:

environment:
  XDEBUG_CONFIG: "remote_host=192.168.1.110"
  PHP_IDE_CONFIG: "serverName=docker-server"

Then I had this in phpinfo(): enter image description here

So in the end what I did was, I removed environment directive and put back the env_file directive and inside environment.development file I removed the double quotes around the value, so now it looks like that:

XDEBUG_CONFIG=remote_host=192.168.1.110
PHP_IDE_CONFIG=serverName=docker-server

And now it works fine :)

I filled a bug report in PhpStorm youtrack.

Just to complete this, you can set this env variable directly in PHPStorm in the config of the CLI Interperters. Just take care to remove the double quotes too.
Thanks for sharing this with up. For me just putting ` environment: - PHP_IDE_CONFIG=serverName=docker-server` did the fix. you don't really need env_file, just remove the quotes.

I had the same issue with double quotes but in docker-compose. First version was wrong, removing double quotes solved it:

    environment:
      - PHP_IDE_CONFIG="serverName=local"
      - PHP_IDE_CONFIG=serverName=local
