Is this still a problem for you?

Hey Derick, this problem still exists. From Zend Server 8.5 and on XDebug comes bundled. If you enable Z-Ray in combination with XDebug and start a remote debug session it will always halt execution in zray.php first when using the break at first line logic.

Due to Z-Ray, the break at first line logic will render unexpected debug behaviour. Disabling the break at first line functionality, and using normal breakpoints does work properly.

If this is their auto_prepend file, or something similar through an extension, there is little I can do about this. The "break at first line" is functionality provided by an IDE - perhaps you can convince them to not stop at a first line if the file is zray.php?

No it's an iframe that runs on the same domain. The question is: because it's an iframe should I see 2 debug calls or not?

PHPStorm offers 'skip' Z-Ray functionality indeed for the Zend Debugger, just not for XDebug.

Yes, you should see two calls. PhpStorm does support multiple simultaneous debugging connections, but you need to turn that on at Languages & Frameworks ? PHP ? Debug ? External Connections ? Max. simultaneous connections.

If you increase that from 1 to something higher, you should get two debugging sessions. I would ask PhpStorm to also allow the "Ignore Z-Ray system requests" flag to work for Xdebug - they have an issue tracker at https://youtrack.jetbrains.com

Thx jvandijk for stepping in. I'm currently far away from php more in .net and javascript.

@derick:
Yes the problem is phpstorm offers to disable zray for debug sessions. I hope you can find a solution... probably talking to the guys from jetbrains or zend?

(Flipping this back to Feedback to allow @jvandijk to give feedback on the simultaneous connections setting in PhpStorm)

@jvandijk ?

I am closing this, as this does not seem to be a bug in Xdebug. Please feel free to reopen this if you can provide more information as requested.
