Hi.
In our project it had often happened that someone debugged the code on the local PC and then forgets to remove calls to debugbreak() when committing files to the repository and so we got problems on the staging server (luckily not in production). Quick googling didn't get me any ready-to-go solutions. So I wrote a tiny simple script that can be used as pre-commit hook for TortoiseSVN and whose only task is to remove the calls to debugbreak. Maybe it'll be useful for someone else, so I'm putting it on github - https:/ /github.com/ruslanbes/remove-debugbreaks (remove space between / / )

P.S. Alternative solution is to write somewhere in your application's bootstrap files:

but I prefer to have clean code in the svn.

I thought if the debugger is not running (no debug session cookie set), debugBreak is ignored? So on a live server, it should do nothing?

if debugger is not installed on your life server, debugbreak() function _is_ not available and therefore each call to debugbreak will raise error in php.

What ruslanbes suggests is correct -- it's safe to define your own debugbreak if function is not defined, or wrap each call with similar check.
BTW did you try regular breakpoints & initiate debugger from the IDE or from the browser's debugger toolbar?
In this case you'd not need debugbreak at all.

Wrapping each call has the primary downside that when another dev checkouts your code and suddenly gets a debug-stop it could be really annoying. )
And sometimes it's hard to use other methods (like in iframe or in the middle of the chain of redirects)

why each? Can you add your own wrapper function and call it instead of debugbreak?
