How to identify if given number is there in a given array range?

I have an array which stores numbers. The count of numbers varies time to time. There is another variable which a holds number, and I need to find out in which range $num falls. In the above case $num falls under 64. (Bigger than 32 and less than 64)

$ar = array(0, 32, 64, 96, 128, 160, 192, 224);

$num = 44;

How do I crack this?

Solution 
  • $ar = array(0, 32, 64, 96, 128, 160, 192, 224);

$num = 44;

$range = min(array_filter($ar, function($i) use($num) {
    return $i > $num;
}));

var_dump($range);
