I'm currently trying to fix a Mockery bug and, while deep in the code, I came across a piece of code which gets eval'd. Mainly to understand better what's going on, I wanted to step debug it. I first set a breakpoint before the eval call and then tried to step into the eval'd code, but that didn't work out, Netbeans just moves along to the next line.

What *did* work, is setting a xdebug_break() call inside of the code that will be eval'd - and BAM! it works! Netbeans picks up the signal and everything works just as with regular code - you can view the values of the variables, step in, step out and step over code.

Xdebug is full of awesome.

Happy hackin'!

I'm currently working on some Symfony2 bundles and I have one Netbeans project for the main Symfony2 app and one project for the bundle. The bundle files are completely separated from the app and they are just linked (ln -s) together. It works great, except for the case when I need to debug some part of the bundle's code with Netbeans + xdebug. The debugger starts for the "main" project, which is the Symfony2 app, but setting breakpoints with Netbeans (y'know, by clicking the line number) for the bundle doesn't really work, as those are in the other project and not in the debugged one, rendering the whole debugging useless.

The solution is pretty easy actually: instead of setting breakpoints with Netbeans, use xdebug_break() where you want the break to happen and it will happily be caught by the IDE. After the break happened use the "Step into" (F7) functionality to see what's going on.

I've spent this weekend hacking on some unit tests for Zend\Dojo and I ran into an issue where I need Xdebug to, well, debug. Note, that this is not for debugging a Zend Framework application, but for debugging Zend Framework itself. I am using Netbeans + Xdebug to debug regular code, but debugging unit tests was something completely new for me. Turns out, it's not entirely different from "regular" debugging.

Greatest help to figure out this was Raphael Dohms' blog post "Debugging PHPUnit tests in Netbeans with Xdebug". Almost worked out fine, but Netbeans complained about a missing index file and the autoload of files was... not really working. After a bit of poking around, the solution was to go to File -> Project Properties -> Run Configuration and set the "Index File" to /path/to/zend_framework_2/tests/_autoload.php - no more missing index file and the autoload works too!

Starting the debug session stays the same as explained in Raphael's post: click "Debug project" (CTRL+F5), go to the terminal and just type something like:

robert@odin:~/www/zf2/tests$ /path/to/phpunit-debug Zend/Dojo/DojoTest.php

Netbeans will pick up the connection and debugging can start!

Happy hackin'!
