PHPStorm，Docker和调试

Question

I'm trying to debug php code with PHPStorm. I'm on a Mac with docker. I configured xdebug on docker using:

zend_extension="/usr/local/lib/php/extensions/no-debug-non-zts-20151012/xdebug.so"
xdebug.remote_enable = 1
xdebug.remote_connect_back=1
xdebug.idekey = "PHPSTORM"

Then I open the listening on PHPStorm, set the cookie in the browser and then load a page setting a break point in the corresponding point. It happens that, PHPStorm detect an incoming connection, and asks me to accept the connection. I click on accept, the debug fills with the variables and after 1 second, the connection stops and the debugging session ends.

What am I doing wrong?

Answer 1

I was not able to get xdebug.remote_connect_back=1 to work for me.

Instead, you need to provide the IP address of the docker host. Since the docker 18.03 release, you can reference the host.docker.internal DNS entry from within running docker containers.

You should try the following:

1. Remove the xdebug.remote_connect_back=1 line. The default value is 0.
2. Add xdebug.remote_host=host.docker.internal

The rest of your steps sound correct.
