sort 2dimension array with associative key

[phprookie72]

I have an array as follow

$data=array('team1'=>array('w'=>0,'l'=>1,'t'=>0,'pts'=>0', team2'=>array('w'=>1,'l'=>0,'t'=>0,'pts'=>3), 'team3'=>array('w'=>0,'l'=>0,'t'=>1,'pts'=>1) )

 

I would like to sort the data useing pts key in descending order, how would i go about doing that?

thanks.

foreach ($data as $team => $value) $tmp[] = $value['pts'];
array_multisort($data, SORT_DESC, SORT_NUMERIC, $tmp, SORT_DESC, SORT_NUMERIC);
