Cpanel Cron作业未完全运行我的php代码

我有一个cron作业设置来运行一个php脚本，该脚本将抓取一个站点，获取数据并放入mysql数据库。如果我只是导航到url，代码工作正常。对于每个新记录，我都会收到“New Record Created Successfully”（新记录创建成功）消息，这些记录都在我的数据库中。但是当我的cron运行它时，我只得到数据库连接的“connectedsuccessfully”消息。似乎没有别的办法。我的参赛脚本如下

<?php

//nba spider

require 'simple_html_dom.php';

//Upload a blank cookie.txt to the same directory as this file with a CHMOD/Permission to 777
function login($url,$data){
    $fp = fopen("cookie.txt", "w");
    fclose($fp);
    $login = curl_init();
    curl_setopt($login, CURLOPT_COOKIEJAR, "cookie.txt");
    curl_setopt($login, CURLOPT_COOKIEFILE, "cookie.txt");
    curl_setopt($login, CURLOPT_TIMEOUT, 40000);
