Flow3 Debugging

Question

I'm currently evaluating Flow3 for an upcoming project. The AOP Pattern and Dependency Injection would be just ideal for our purpose.

Now what I can't figure out is how to debug some results in a controller Action.

public function testAction() {
    $beans = $this->coffeeBeanRepository->findAll();
    var_dump($beans); // doesn't work, browser crashes
}

What I've tried:

• Debugging with PHPStorm and XDEBUG (this is how I do it usually)
• var_dump / print_r / print

Answer 1

You want to use FLOW3's var_dump, which deals with some of the recursion that comes from deeply nested objects and causes your browser to cache:

\TYPO3\FLOW3\var_dump()

XDebug can be tricky in FLOW3 because FLOW3 creates proxy classes for your classes in order to make all the AOP magic happen. Still, I know the developers here are using xdebug_break() successfully in PHPStorm on their FLOW3 projects, so it's definitely doable.

Answer 2

Xdebug is not so tricky, your cached PHP files must be used to debug purpose, if you need to debug MyController, search for a MyController_Original in the cache directory and put your break point in this file.

You can also use debugproxy.php to improve the usage of xDebug with Flow: https://github.com/sandstorm/debugproxy

Answer 3

In the newest version of Typo3 Flow you have to use:

\TYPO3\Flow\var_dump('test');
