php foreach loop with condition?

Question

I want to loop only if points are greater than levels. The result I want is "reward0"

The sum of points is 80 so greater than 50 but less than 100 so only one reward is required.

I tried like this but no luck.

$levels = [50, 100, 150, 200];
$points = 0;
$rewards = [];


foreach ($levels as $key => $level) {

    if($points >= $level) { 
        $rewards[] = 'reward' . $key;
    }

    // 20, 40, 60, 80
    $points += 20; 

}

return $rewards;

Please expand on no luck. Do you get an error? Is this in a function? return maybe should be print_r? Also not clear about points is 80 so greater than 50 but less than 100 — user3783243

Can you please explain the Logic clearer? I could not nderstand the logic. — Harish ST

In the above code, the execution will not enter into the if condition. That is, the if condition never becomes true. Thus $rewards array will be always empty. — Harish ST

If I understand your logic, then this is what you want,

<?php
$levels = [50, 100, 150, 200];
$points = 0;
$rewards = [];
$points = count($levels) * 20;
$rewards = array_filter($levels, function($n) use ($points){ 
    return $n < $points;
});
print_r($rewards);

If this is the logic, why we need to use foreach? We can simply discard foreach and replace it with $points = count($levels) * 20;. Right?
