Summary0001125: XDEBUG not working with Zends Zray
DescriptionIf you disable the Zend debugger and use Xdebug instead.
The following Problems occure:
The Debug session will always start @ zray.php
If you disable zray it's the same.

What zend does with there debugger: They seem to disable zray for the debug session. So it could be a zend problem or a xdebug feature/workaround.
Steps To Reproduce- Install ZendServer 8
- Install xdebug (pecl)
- Disable the zend debugger and add the extension.
- Listen for incomming debug requests
- Create a file index.php add a breakpoint
- Reload the page it will not break @ index.php -> It looks like zray is loaded before any request on the same host (localhost) with the same php.ini and thats a problem for xdebug.
TagsNo tags attached.

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 [^]

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

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)

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.
