How to check if an integer is within a range?


Is there a way to test a range without doing this redundant code:

if ($int>$min && $int<$max)

?

Like a function:

function testRange($int,$min,$max){
    return ($min<$int && $int<$max);
}

usage:

if (testRange($int,$min,$max)) 

?

Does PHP have such built-in function? Or any other way to do it?


Solution

  • Tested your 3 ways with a 1000000-times-loop.

    t1_test1: ($val >= $min && $val <= $max): 0.3823 ms

    t2_test2: (in_array($val, range($min, $max)): 9.3301 ms

    t3_test3: (max(min($var, $max), $min) == $val): 0.7272 ms

    T1 was fastest, it was basicly this:

    function t1($val, $min, $max) {
      return ($val >= $min && $val <= $max);
    }
