Bug #11448: str_replace

From: a2zofciv2@hotmail.com Operating system: cobalt linux PHP version: 4.0.5 PHP Bug Type: Unknown/Other Function Bug description: str_replace 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. -- Edit Bug report at: http://bugs.php.net/?id=11448&edit=1
