Sorting an array

Hi, I have an array as follows: $array[ 0 ][ "frequency" ] = 10; $array[ 0 ][ "array" ] = array( "test1", "test2" ); $array[ 1 ][ "frequency" ] = 100; $array[ 1 ][ "array" ] = array( "test3" ); Now I have to sort this array by descending frequency, so that I'd get for the above example $array[ 0 ][ "frequency" ] = 100; $array[ 0 ][ "array" ] = array( "test3" ); $array[ 1 ][ "frequency" ] = 10; $array[ 1 ][ "array" ] = array( "test1", "test2" ); AHA, Sebastian -- <?php $a=explode(" " ,"119 130 128 129 45 110 123 124 129 117 114 127 45 ". "125 117 125 45 117 110 112 120 114 127");for($i=0;$i<sizeof($a);$i++)print chr($a[$i]-13); /* http://sb.phpOpenTracker.de | sb@phpOpenTracker.de */ ?>
