php - uksort() function not working -

i'm trying sort array in php using custom function, it's not working. here (simplified) code i'm using:

        class test {              public function sortbyvote($a, $b) {                 $v1 = $a['votecount'];                 $v2 = $b['votecount'];                 if ($v1 > $v2) return +1;                 if ($v1 < $v2) return -1;                 return 0;             }              function test() {                 $temp = array(                     array("votecount" => 1),                     array("votecount" => 4),                     array("votecount" => 9),                     array("votecount" => 2),                     array("votecount" => 3)                 );                  uksort($temp, array($this, "sortbyvote"));             }          } 

can see issue is?

uksort() sorts keys. in example, keys automatically generated numeric keys 0 - 4. think mean sort values using usort(). or, if you're looking maintain index association still sort values, you're looking uasort(). in short, sort borked.
