Hi,
okay i was bored and was tryign to make a matrix like thing, with green text and marquees and used PHP for() loops abd stuff and random number generators..
but whenever i run it on local system everything crashes  internet explorer's memory usage goes to unbelivavble amounts (INTO GB!!!!) eventually stops responding and everything just crashes.
the script:
PHP Code:
<?php
/* ********************************
Random String Generator
- used for forgot password script.
***********************************/
function assign_rand_value($num)
{
// accepts 1 - 36
switch($num)
{
case "1":
$rand_value = "0";
break;
case "2":
$rand_value = "1";
break;
case "3":
$rand_value = "2";
break;
case "4":
$rand_value = "3";
break;
case "5":
$rand_value = "4";
break;
case "6":
$rand_value = "5";
break;
case "7":
$rand_value = "6";
break;
case "8":
$rand_value = "7";
break;
case "9":
$rand_value = "8";
break;
case "10":
$rand_value = "9";
break;
case "11":
$rand_value = "10";
break;
case "12":
$rand_value = "11";
break;
case "13":
$rand_value = "12";
break;
case "14":
$rand_value = "13";
break;
case "15":
$rand_value = "14";
break;
case "16":
$rand_value = "15";
break;
case "17":
$rand_value = "16";
break;
case "18":
$rand_value = "17";
break;
case "19":
$rand_value = "18";
break;
case "20":
$rand_value = "19";
break;
}
return $rand_value;
}
