The results of this are run through array_unique, so only arrays with unique signatures are left. array_intersect_key will take the keys of the unique items from the map/unique function (since the source array's keys are preserved) and pull them out of your original source array. Share I...
<?php // input data $arr = array( array('field1-1', 'field1-2'), array('field2-1', 'field2-2'), array('field3-1', 'field3-2'), array('field4-1', 'field4-2'), ); // some basic validations on input data if (empty($arr) OR (!isset($arr[0])) OR (empty($arr...
