php简单防盗链验证实现方法 原创
这里分析了php的简单防盗链实现方法。分享飞大家供大家参考。具体如下：
index.php页面如下：
<html> <head> <meta http-equiv="Content-Language" content="en" /> <meta name="GENERATOR" content="PHPEclipse 1.0" /> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>防盗链</title> </head> <body> <form action="check.php" method="post"> 提交信息：<input type="text" name="name" value=""/> <input type="submit" name="submit" value="提交"/> </form> </body> </html>
check.php页面如下：
$urlar=parse_url($_SERVER['HTTP_REFERER']);
print("<pre>");
print_r($urlar);
print_r($_SERVER['HTTP_REFERER']);
if($urlar['host']!="localhost"){//此处可替换成当前使用的域名
echo "验证错误！";
echo "<script>alert('连接失败');location.href='index.php';</script>";
exit;
}
print("</pre>");希望本文所述对大家php程序设计有所帮助。
