If you have an array with NULL values but if you want to remove the NULL values from that array without loop. In PHP array_filter function helps to remove all null values from array.

$result1 = array_filter($example1, function($value) {
			  return !is_null($value);
			});
print_r($result1);

The Output as follows:

Array
(
[0] => 100
[1] => Priya
