实现任意html页面跳转代码

<?php
//本代码添加到任意html上面即可，不影响正常html的使用。
//$referer = $_SERVER['HTTP_REFERER'];
$to = $_GET['t'];
//如果不是从a站lp页面来的并且t参数不等于1024，那么就不执行js跳转
//if ($to=='1024' and $referer == "https://baidu.com") {
if ($to=='1024') {
    //当前lp所在页面地址
//    $link = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];//如果是二级域名一定要填写，如果是根域名或www那就去掉test
    $link = 'https://' . $_SERVER['HTTP_HOST'];//如果是只要主页不要后面的.php或目录，可以去掉$_SERVER['PHP_SELF']

    $togo = 'https://baidu.com';//offer链接地址
    echo '<script>
        var hUrl = "'.$link.'";
        if (hUrl!=""){
            var htxt = "Wait a second ...";
            history.replaceState(null, htxt, hUrl);
            history.pushState(null, htxt, hUrl);
            history.pushState(null, htxt, hUrl);
            history.pushState(null, htxt, hUrl);
    
            delete window.document.referrer;
            window.document.__defineGetter__("referrer", function () {
                return hUrl;
            });
            window.location.replace("'.$togo.'");
    
            location.href ="'.$togo.'";
        }
    
        </script>';
}
