Hi
The whole PHP script is being executed at once and you cannot have a scope for it but if you want to simulate it behavior you can write a function like this and call it at the end of the your <?php ?> tags

function clear() {
    $vars = array_keys(get_defined_vars());
    foreach($vars as $var) {
        unset(${"$var"});
    }
}

And your code will be like this

<?php

// some php codes

clear()
?>
