sort by multiple conditions using uasort() php

I have array of json objects and I want to sort it ascending and also put the null values in the end. following is the code I tried. Both uasort() is working perfectly fine individually but When I put them one after another, it just sort the array based on the latest function.

How can I sort the array in ascending order and also put null values at the end of that ascending sorted list?


uasort($arr, function($a,$b) { 
        return $a->score > $b->score ? 1 : -1; 
    });

uasort($arr, function($a) {
     return ( is_null($a->score==NULL) OR $a->score == "") ? 1 : -1;
});

Use one comparison function that tests both conditions.

uasort($arr, function($a, $b) {
    if ($a->score === $b->score) {
        return 0;
    }
    if ($a->score === NULL || $a->score === "") {
        return 1;
    }
    if ($b->score === NULL || $b->score === "") {
        return -1;
    }
    return $a->score > $b->score ? 1 : -1; 
}
