Note Submitter: fierojoe@fierojoe.com ---- I could not find a good way to search an array of associative arrays and return the key of the found array, so I created this function to do it. It's very handy to search through the results of a mysql_fetch_assoc(). <?php $a = array( array('id' => 1, 'name' => 'oranges'), array('id' => 2, 'name' => 'apples'), array('id' => 3, 'name' => 'coconuts'), ); function _array_search($s, $a) { for($i=0; $i <= count($a); $i++) { if (in_array($s, $a[$i])) { return($i); break; } } return(FALSE); } //returns key 0 for the second element, 'id' => 1 echo _array_search(1, $a); //returns key 2 for the second element, 'id' => 3 echo _array_search(3, $a); //returns key 1 for the second element, 'id' => 2 echo _array_search(2, $a); ?>
