创建个PHP文件丢到你网站随便地方访问，访问后不会出现结果，等待个20秒左右关闭页面，就会自动执行了，执行以后除非重启PHP服务或者直接重启服务器，不然会一直嗨下去

    <?php
    //设置脚本运行不超时
    set_time_limit(0);
    //即使浏览器关闭还继续运营
    ignore_user_abort(true);
    //睡眠5秒
    sleep(5);
    //要监控的网址
    $cronurl = 'https://www.baidu.com/';
    //开始get监控
    httpGet($cronurl);
    //这里还可以无限加httpGet("网址");一次性多嗨几个
    //获取当前文件的访问url
    $url="http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
    //开始get自己，简称自嗨，达到无限循环的效果
    httpGet($url);
    //发起GET模拟请求
    function httpGet($url) {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_TIMEOUT, 30);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_HTTPHEADER,array('Accept-Encoding: gzip, deflate'));
        curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate');
        curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (iPhone; CPU iPhone OS 8_0 like Mac OS X)        AppleWebKit/600.1.3 (KHTML, like Gecko) Version/8.0     Mobile/12A4345d Safari/600.1.4");
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 3);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        $output = curl_exec($ch);
        curl_close($ch);
        return $output;
    }
