将数组从JavaScript传递给PHP然后再传回JavaScript

I need to pass an array from one page to a PHP page to get it to write it to a file, then another page has to access that file an array in the second page.

我需要将一个数组从一个页面传递到一个PHP页面以使其将其写入文件，然后另一个页面必须在第二个页面中访问该文件和一个数组。

So far i have an array in JavaScript loaded with all the info I need:

到目前为止，我有一个JavaScript数组加载了我需要的所有信息：

JavaScript code:

JavaScript代码：

$.ajax({
        url: 'woepanel.php',
        type: 'POST',
        dataType: "json",
        data: vars,
     });

PHP code:

PHP代码：

<?php
$datap = array(json_decode($_POST['data']));
file_put_contents('var.txt', print_r($datap, true));
?>

As for the page pulling I'm unsure on how to accomplish this..

至于页面拉动我不确定如何完成这个..

Best way is to use proper JSON both ways, i.e. you need to stringify the JSON before sending it, as otherwise it would be passed as a regular URL param, so:

最好的方法是两种方式使用正确的JSON，即你需要在发送之前对JSON进行字符串化，否则它将作为常规URL参数传递，因此：

javascript:

JavaScript的：

$.ajax({
    url: 'woepanel.php',
    type: 'POST',
    dataType: "json",
    data: JSON.stringify(vars),
 });

php:

PHP：

$json = file_get_contents('php://input');
$array = json_decode($json);

Are you sure that the array contains the "data"-key? Try this

你确定该数组包含“数据”键吗？尝试这个

$.ajax({
url: 'woepanel.php',
type: 'POST',
dataType: "json",
data: {
    "data" : vars
  },
});
