Sorting objects in array

I have an array of objects containing a number of values. The values are set correctly and the data inside this array is also shown in correct way accoring to the order of objects.

What i would want now ii that the order is changed. In this particular example according to the objects 'Point' value, so the objects with the highest Pointvalue is first and so on...

What I tried to do was finding the object with the highest value, push it in the array and unsetting the original value. And with array_slice getting the relevant array elements in the end.

I also succeeded in the first part, but the problem is I keep finding the same object, so i somehow doesn't remove it from the array.

$max = $obj[0];
    for ($j =0; $j<count($obj)-$j; $j++) {
        for ($i=0; $i<count($names); $i++) {
            if ($max->Point < $obj[$i+1]->Point) {
                $max = $obj[$i+1];
            }
        }
        if ($max->id == $obj[$j]->id) {
            unset($obj[$j]);
        }
        array_push($obj, $max);
    }

I'm not sure you can see through the code and what I'm trying to do, but hopefully someone can and either show my mistake(s), or show others way to accomplish the same?

Try using the usort() function. It allows you to sort the array according to a comparison function that you define.

function lower_points($a, $b) {
    if ($a->Point == $b->Point) return 0;
    else if ($a->Point > $b->Point) return -1;
    else return 1;
}

usort($array_of_objects, lower_points);
