    <?php
    $n = 25;
    function Res()
    {
        $n = 15;
        echo "$n";
    }
    Res();
    echo "$n";
    ?>
    1. 25
    2. 15
    3. 1525
    4. Error
    5. None of these

First when the function is called variable n is initialised to 15 so 15 is printed later the global value 25 is printed.
