Summary	0000958: XDebug doesn't breakpoint at code called by preg_replace (Might affect other functions)
Description	If you make preg_replace call a function when replacing some text, any breakpoint set in the function isn't honoured.
Steps To Reproduce	In this code, place a breakpoint in line 5 ("echo $txt") and another in line 8 ("return 'h';"). Execution stops at line 5, but not at line 8. <?php $txt="AaAaAaAaAa"; $txt=preg_replace(array('/[a-z]/e'), array("replace(\"$1\")"), $txt); echo $txt; function replace($txt) { return 'h'; } ?>
Tags	Doesn't Break

derick 2013-10-09 18:36 administrator ~0002573	I've had a look at this and I can see what is wrong. Requires hackyness for preg replace and "regexp code" in filename checks.

derick 2017-03-19 22:15 administrator ~0004236	I had a look at this again, and the /e modifier is no longer available in PHP 7.x for preg_replace - instead, you need to use preg_match_replace. As this is sort of a new feature, which would only apply for PHP 5, I have decided not to add this new "hacky" functionality that relies on string matching a filename.
