Reproduce code: --------------- Interactive mode enabled $string = "He had had to have had it"; $newstring = str_replace("had", "foo", $string, $count); print "$count changes were made.\n"; changes were made. $count = 0; $newstring = str_replace("had", "foo", $string, $count); echo $count; 3 (Note: due to ambiguity in the manual, I tried using $count and &$count as I wasn't sure which was correct - both failed to work) Expected result: ---------------- I would have expected either a warning, "Unknown variable $count", or, otherwise, for PHP to create $count and set it to the right value. Actual result: -------------- $count didn't get set ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24281&edit=1
