Use PHP to select an even number in the array.

I have a small algorithm that selects all the even or the technology in the array. A lot of people may, would loop this array, and I just do not loop the array can do this, the code is as follows.

function Odd ($var) {    //returns whether the input integer is odd    return ($var & 1);} function even ($var) {    //returns whether the input integer is even    return (! ( $var & 1));} $array 1 = Array ("A" =>1, "B" =>2, "C" =>3, "D" =>4, "E" =>5), $array 2 = Array (6, 7, 8, 9, ten, one,); echo "ODD: \ n ";p rint_r (Array_filter ($array 1," odd ")), echo" even:\n ";p Rint_r (Array_filter ($array 2," even "));
