        case "!=": return $var1 != $var2;
        case ">=": return $var1 >= $var2;
        case "<=": return $var1 <= $var2;
        case ">":  return $var1 >  $var2;
        case "<":  return $var1 <  $var2;
    default:       return true;
    }   
}

Test:

$ops = array( "=", "!=", ">=", "<=", ">", "<" );
$v1 = 1; $v2 = 5;

foreach ($ops as $op) {
    if (num_cond($v1, $op, $v2)) echo "True  ($v1 $op $v2)\n"; else echo "False ($v1 $op $v2)\n";
}
