[TYPO3-english] print_r worries

Hey there.

The hint was not to use anything that prints output but a breakpoint provided by xdebug. Whatever you want to do, you most likely want to "just look a bit around". Besides the one property you currently expose through print_r there are a lot of other things you might want to see. What do you do currently? Adjust print_r until either having found the desired values or having reached $GLOBAL? Since I have an IDE connected to xdebug, I haven't used print_r a single time.

What's the reason for print_r at all?
Do you need to be reminded about property names or getter and setter methods of your objects? Use proper type hinting and an IDE being aware of that, you most likely can just go on coding with "->[ctrl+space]" without even starting a PHP process. There's nothing better than having an IDE complaining about type incompatible method calls *before* trying to execute that part of a script.
Do you want to know about attributes of arrays? Use xdebug and have almost everything in one single view, starting with $GLOBALS[TSFE] if you need to.

So really, you should start using xdebug and an IDE that provides you with type hinting.

But if you really want to keep using your browser output for debugging (and I call everything debugging that isn't regular production ready requests) you should use:
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump().

Hi,

Since '97 I solely use Linux and as editor vim.

I tried Eclipse and Netbeans but all those UIs seem to bloated for me and change constantly. You always have to adopt to a changed interface.

Tried the "xdebug_var_dump()" which comes with xdebug but this yields the same problems. I will give the DebuggerUtility::var_dump() a try.


there is an xdebug interface for vim but I am not very used to it. This
could result in a discussion: I think debugging and just doing some
print_r's while developing are two different things. Altough I try to
use Test-Driven-Development in recent projects in comes out that this
approach is quite complicated when extending some existing code. At
least harder than for developing something new.



greetings,
Bernhard
