Sorry, I misread you. I thought you were referring to replacing the
second '&', not the first one. I didn't even spot that the two boolean
expressions were being combined with a bitwise operator (which I agree
is wrong).
For reference, the function in question was:
function is_even($num){
return (is_numeric($num)&(!($num&1)));
}
