detect an odd or even number function

Is there a php function to detect an odd or an even number?

There is now (see below). Just use the modulus. Like

PHP Code:


		
			
function is_even($a){

    $even = True;

    if ($a % 2 != '0'){

        $even = False;

    }

    return $even;

}

// example

for ($i=0;$i<=1000;$i ++){

      if (is_even($i){

           echo $i . ' is an even number.<br />';

      } else {

           echo $i ' is an odd number.<br />';

      }

}
