推荐答案

PHP的快速而又肮脏的解决方案.

Quick and Dirty Solution For PHP.

每次他们访问页面时，它都会增加计数器的数量.太多次意味着页面die().您可以选择将此代码放置在仅当有人提交表单时才执行的位置.

Everytime they visit a page, it increments the counter. Too many times means the page die()s. You can choose to put this code in a spot where it will only be executed when someone submits the form.

它经常重置计数.

已知的错误:清除Cookie会破坏它，关闭cookie会破坏它.

Known Bugs: Clearing Cookies breaks it, having cookies off breaks it.

<?php

session_start();

if(!isset($_SESSION['count']))
{
   $_SESSION['count'] = 1;
   $_SESSION['first'] = time();
}
else
{
   // Increase the Count
   $_SESSION['count']++;
   // Reset every so often
   if($_SESSION['first'] < (time() - 500))
   {
      $_SESSION['count'] = 1;
      $_SESSION['first'] = time();
   }
   // Die if they have viewed the page too many times
   if($_SESSION['count'] > 100)
   {
      die("You have submitted to many times");
   }
}
