sorting mulidimensional array by value?

[zander1983]

I have an array and when i do a print_r(), i get this:

 

Array ( [0] => Array ( [path] => 1 [order] => 2 ) [1] => Array ( [path] => 2 [order] => 2 ) [2] => Array ( [path] => 3 [order] => 1 ) )

 

I want to sort it so that the array with an order of 1 is at the front, i.e. that last array in this case. I tried asort but that didnt do anything...

got it, i used this:

 

<?php
     // Sort the multidimensional array
     usort($results, "custom_sort");
     // Define the custom sort function
     function custom_sort($a,$b) {
          return $a['some_sub_var']>$b['some_sub_var'];
     }
?>
