preg_grep changed after php4.0.4+

It does not appear to be in the documentation yet (and only a little blurb in the NEWS file) but preg_grep has changed. Assume $file_list is an array of file names using integer keys, e.g., $file_list { 0 => "test", 1 => "filenames" } $result = preg_grep("/name/i", $file_list); Here is an example of what used to work: print_r($result) would print $result { 0 => "filenames" } So you could use $result[0] to get the value "filenames". They way it works now: print_r($result) prints $result { 1 => "filenames" } So you have to search $result for array_keys and then use the result of that on the original array. $keys = array_keys($result); and use $file_list[$keys[0]] to get the value "filenames" -or- create a for loop over $result -or- have the prescience to know the right key in $file_list to start with ;-) Is this documented somewhere? The current PHP manual on php.net & zend does not reflect this change. The change broke my script when I upgraded from 4.0.1... to 4.0.4+ Documentation could well be the achilles heel of open source. -A
