note 85109 deleted from function.array-unique by cmb

Note Submitter: soapergem at gmail dot com ---- Here's another solution for returning an array that only includes repeated values. There is one given below but it only works on numerically indexed arrays; this one is more comprehensive since I used the foreach iterator. Also, this one preserves keys--in that the returned result contains a distinct list of repeats (storing only the first instance it encounters of each duplicate value). <?php function array_repeated($array) { if ( !is_array($array) ) { return false; } $duplicates = array(); foreach ( $array as $key => $val ) { end($array); $k = key($array); $v = current($array); while ( $k !== $key ) { if ( $v === $val ) { $duplicates[$key] = $v; break; } $v = prev($array); $k = key($array); } } return $duplicates; } ?>
