	public static function ds($bet){<br />		return count(explode('|', $bet));<br />	}
Copy after login

以上我的PHP代码,现在出现了注入漏洞,使用以下代码可以从网页上提交
<script type="text/javascript"> <br />var game={<br />type:"1",<br />played:"10",<br />groupId:2},<br />user="langlang",<br />aflag=false;<br /></script>
Copy after login

我想限制使用代码提交,请问怎么写?
