php - Is there a way to count integers in an array less than a given point without a foreach loop? -

is possible count integers in array match criteria (e.g. less n) without foreach loop?

$arr = range(0,100); // not consistent 0,1,2,3...100.  1,1,3,5,25,6,10,100. $n = 20; echo countlessthan($n,$arr); // can work without loop? echo countlessloop($n,$arr); // works, of loop  // can make work without loop? function countlessthan($n,$arr) {     $count = ?; // number of items in $arr below $n     return $count; }  // works, loop function countlessloop($n,$arr) {     $count = 0;     foreach($arr $v) {         if ($v < $n) $count++;     }     return $count; } 

one generic method can use of array_filter function creates array of elements meeting criterion (given function name)

for example count number of elements in array bigger 3 1 can run

function test($x){  return $x>3;  }  $data = array( 1,2,3,4,5 ); echo count( array_filter( $data, 'test' ) ); 

which prints

2 

but - without restrictions on criterion and/or array - solution use loop "under hood" (and provided answer loops, using language predefined functions).
