It's documented (I've translated a week ago.) <manual> Since PHP 4.0.4, the results returned by preg_grep() are indexed using the keys from the input array. If this behavior is undesirable, use array_values() on the array returned by preg_grep() to reindex the values. </manual> ----- Original Message ----- From: <alanjc45@yahoo.com> To: <php-general@lists.php.net> Sent: Sunday, November 04, 2001 8:35 PM Subject: [PHP] 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?
