<?php
if($_GET['pass'])
{
$usrinput = $_GET['pass'];
}
else
{
$usrinput = $_GET['newpass'];
}

$output = strlen($usrinput); // periksa panjang dari pass
function CheckForUPcase($text, $limit = .1)// periksa apakah ada uppercase
{
$len = strlen($text);
$upperCaseCount = 0;
for($i = 0; $i < $len; $i++)
{
$chr = $text[$i];
$intVal = ord($chr);
if($intVal >= 65 && $intVal <= 90)
{
if(++$upperCaseCount / $len >= $limit) { return true; } } } return false; } function CheckSPCHAR($usrinput) // periksa special karakter { if(!eregi("^([a-z0-9])*$",$usrinput)) { return true; } else { return false; } } function CheckNum($usrinput) // periksa numeric { if(eregi("[0-9]",$usrinput)) { return true; } else { return false; } } //CheckForUPcase($usrinput); if(CheckNum($usrinput)==true&&CheckForUPcase($usrinput)==true&&CheckSPCHAR($usrinput)==true&&$output>='8') { echo '<img src="images/usecure.gif" width="186"/> 
Uber Secure! (Best)'; }elseif((CheckForUPcase($usrinput)==true&&CheckSPCHAR($usrinput)==true&&$output>='8')||(CheckNum($usrinput)==true&&CheckSPCHAR($usrinput)==true&&$output>='8')||(CheckNum($usrinput)==true&&CheckForUPcase($usrinput)==true&&$output>='8')||(CheckNum($usrinput)==true&&CheckForUPcase($usrinput)==true&&CheckSPCHAR($usrinput)==true)) { echo '<img src="images/secure.gif" width="186"/>
