回答1:

Use the following approach:

$marks = array
(
    3 => 2, // skill => eligible marks
    63 => 6,
    128 => 3
);

// $arr is your initial array of student data
$student_ids = [];
$marks_count = count($marks);
foreach ($arr as $k => $items) {
    // if number of marks coincide
    if (count($marks) != count($items)) continue;

    foreach ($items as $item) {
        if (!isset($marks[$item['skill_id']]) 
                || $marks[$item['skill_id']] >= $item['gd_score']) {
            continue 2;
        }
    }
    $student_ids[] = $k;
}

print_r($student_ids);

The output:

Array
(
    [0] => 24
)
