result.php

<html>
    <meta charset="UTF-8">
    <body>
        <?php
            $input = $_REQUEST["Input"];
            $count = 0;
            for ($i = 0; $i < $input; $i++)
            {
                $x = $input % 10;
                if ($x % 2 == 0)
                {
                    $count++;
                }
                $input = (int)($input / 10);
            }
        ?>
        Числото <?php echo $_POST["Input"]; ?> съдържа <?php echo $count ?> четни цифри.
    </body>
</html>

Change to:

<html>
    <meta charset="UTF-8">
    <body>
        <?php
            $input = str_split($_REQUEST["Input"]);
            $input_length = count($input);
            $count = 0;

            for($i = 0; $i < $input_length; ++$i){
                if($input[$i] % 2 === 0){
                    ++$count;
                }
            }
        ?>
        Числото <?php echo $_POST["Input"]; ?> съдържа <?php echo $count ?> четни цифри.
    </body>
</html>
