<?php
session_start();
ob_start();
require('connect.php');
	
if(isset($_POST['doe'])){
	
	$query = mysql_query("SELECT * FROM login WHERE tijd"); 
	$result = mysql_num_rows($query); 
	while($object = mysql_fetch_object($query)){ 
		$tijdlaatst = $object->tijd;
	}
	$tijdnu = time();
	
	if($tijdnu >= ($tijdlaatst + 10)){
	
	
	mysql_query(" --- `login` (tijd) VALUES ('$tijdnu')") or die(mysql_error()); 
	
	$made = rand(0,100);
	echo "You succesfully commited the crime and made $$made!";
}

	echo "You have to wait 2 minutes before you can commit a crime!";
