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=gbk" />
<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。
