我编写了一个脚本，当我在浏览器中导航到它时，它的功能应该如此。这是我第一次尝试使用 cron 作业，所以我不太熟悉它们的工作方式。脚本如下。正如我所说，如果我在 Web 浏览器中导航到 url，脚本会正常工作。

测试.php

<script src="jquery.min.js"></script>
<script>
//SET UP JS VARIABLES
var allMatchedNumbers = new Array();
var matchedthingyNumbers;
var matchedthingyPlus1Numbers;
var matchedthingyPlus2Numbers;
var winningthingyNumbers = new Array();
var winningBonusNumber;
var winningthingyPlus1Numbers = new Array();
var winningPlus1BonusNumber;
var winningthingyPlus2Numbers = new Array();
var winningPlus2BonusNumber;
var thingyList;
var thingyListItems;
var thingyPlus1List;
var thingyPlus1ListItems;
var thingyPlus2List;
var thingyPlus2ListItems;
var userNumbers = new Array();
var displayCounter = 1;
var drawDate;
var thingyNumbers;
var thingyBonus;
var thingyPlus1;
var thingyPlus1Bonus;
var thingyPlus2;
var thingyPlus2Bonus;

//GET RESULTS & DATE FOR thingy, PLUS1, PLUS2 FROM THE DOM OBJECT ONLY
$(document).ready(function fetchResults(){
    $.ajax({

如果您test.php通过wget或类似方式调用，则该工具 php中没有 JavaScript 引擎。因此，页面的任何依赖于 JavaScript 的功能自然都不会运行。

有一些工具可以加载页面并在其中执行 JavaScript。它们被称为“无头”浏览器。例如，PhantomJS是一个基于 WebKit 的无头浏览器，其中包含一个 JavaScript 引擎。还有无头版本的 Firefox 等。

您将让您的 Web 服务器正常运行，并将无头浏览器指向页面的 URL，这将触发 PHP（就像浏览器已请求该页面一样）并在页。

您尝试运行的脚本包含 Javascript - 在浏览器中执行。Cron 将在服务器上执行PHP脚本，并将输出发送到任何地方（正如您将其定向到/dev/null）。

在那种情况下，没有任何东西可以解释和执行 Javascript。

您需要将 Javascript（向两个相关的 PHP 脚本发出请求）中的逻辑移植到 PHP。（您可能会运行一些服务器端 javascript 解释器/php 扩展，但在这种情况下，这似乎有点疯狂。）
