note 91202 deleted from function.array-keys by danbrown

Note Submitter: timothy dot burgess dot 87 at gmail dot com ---- Oops sorry... this one is better! Ignore my last post. This function is almost exactly the same as the "extract_values_by_key" that was made over at the "array_search" documentation page, but allows for arrays to be returned as well and some weird bug with zeroes is eliminated (for some reason it was treating "if ($needle_key == $key)" as true when the key was "0"). For multidimensional arrays, I noticed someone created a function called "extract_values_by_key" but it didn't work as I wanted it to... so I created a recursive function of my own that gets the values within a multidimensional array with a specific key and stores them into an array in case multiple keys match the search. /* Search for values by key within multidimensional array */ //Timothy Burgess //05.29.2009 function get_values_by_key($array, $needle_key, &$out = array ()) { if (is_array($array)) { foreach ($array as $key => $value) { get_values_by_key($value, $needle_key, &$out ); if ($key == $needle_key && $key != "0") { $out[] = $value; } } } return $out; }
