How to sort this array based on percentage in descending order i tried with this code but it is not working

usort($post_result, array($this, "myfunction"));  
function  myfunction($a, $b)
{
return strcmp($a->percentage, $b->percentage);
}

Read the php manual for usort() and you will figure it out how to change it that it works for you :D If not show us your attempts and where you are stuck and what you don't understand — Rizier123

Try this:

usort($post_result, function($a, $b) {
    if($a['percentage']==$b['percentage']) return 0;
    return $a['percentage'] < $b['percentage']?1:-1;
});
