    Set the p GET variable for setting total loops<br/>
    For example, run:<br/>
    <code><?php
    $n = rand(5 ,100);
    echo( '<a href="'.$_SERVER['PHP_SELF'] . "?p=$n".'">' . $_SERVER['PHP_SELF'] . "?p=$n" . '</a>' ); ?></code> to get <?php echo $n; ?> iterations.<br/>
    Default is 10.
    <hr/>

    <?php
        // get the user GET value
        $p = (int) @$_GET['p'];
        // is p is not set then loop 10 times
        if ($p == '') { $p=10; }

        for ($i=1; $i <= $p; $i++) {
            echo "Hello $i<br/>";
        }

    ?>
