Hi, I have variables called Cookie1 to Cookie35. I would like to print the values of Cookie1 to Cookie35 using for loop. Could anybody correct the below code to print the variables. =============================for($i=1;$i<34;$i++) { $x="Cookie".$i; if(isset($$x)) { echo "<p>$x:$$x</p>"; } }

for($i=1;$i<34;$i++) {

        $x="Cookie".$i;
        eval("\$y = \$$x;");

Why are you using eval? Eval is slow and is a hack... Just do: $y = $$x;

        if(isset($y))
        {
                echo "<p>$x:$y</p>";
        }

}
