Note Submitter: woodspire@hotmail.com ---- This is an addendum to joelith at cyberone dot com dot au's note. First of all, here is the correct code for your example: ... $temp = explode('.', $test); ... There was a variable name error. Also, you may have never heard of the modulus operator, but it's quite simpler with it. Ex: $test = 5 % 2; // $test = 1; $test = 4 % 2; // $test = 0; So, the easiest way to find if a number is even or odd is the following: $test = $number % 2; if ($temp == 0){ // even } else{ //odd }
