Bug #11448 Updated: str_replace

ID: 11448 Updated by: rasmus Reported By: a2zofciv2@hotmail.com Old-Status: Bogus Status: Closed Bug Type: Unknown/Other Function Operating system: PHP Version: 4.0.5 Assigned To: Comments: Uh, Jani, of course you can use a function there. But the function will get evaluated to produce a string which becomes the argument to str_replace(). That's just the way it works. The function will be called every time. If you don't want it called, add the appropriate logic to not call it by checking for the match first with a strstr() call. Previous Comments: --------------------------------------------------------------------------- [2001-06-13 10:57:59] sniper@php.net Where does it say you can use function as the replacement? You have to set it to variable first. --------------------------------------------------------------------------- [2001-06-12 19:07:10] a2zofciv2@hotmail.com the following line: $line = str_replace("pattern", Pattern(),$line); where Pattern() is a function that returns a string. Pattern executes everytime this code line is encountered, even if "pattern" is not a match on $line. so if i loop through a file running that line, the function Pattern() will execute every single time, match or no match. (my) common sense says this function should only execute when a match is found. Is this a bug? I didn't know about it and something like this could seriously affect performance of a program. Also I don't think the modules or any other of your requirements are relevant for this issue. --------------------------------------------------------------------------- ATTENTION!
