data: {'key':'123'},//如果需要字符串json方式，请使用JSON.stringify(setting.data)
type: 'POST',

2.php page
<?php
$arr = get_getallheaders();//获取http头数组
//echo $arr["Token"];//输出Token
var_dump($arr);//输出整个数组
function get_getallheaders() //定义方法
{
foreach ($_SERVER as $name => $value) //循环_SERVER数组
{
if (substr($name, 0, 5) == 'HTTP_') //前5个字符是HTTP_的进入循环
{
$headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value;
//注释
//substr($name, 5)，从$name第5个字符向后截取
//str_replace('_', ' ',)下划线替换成空格
//strtolower()全部转换为小写
//ucwords()首字母转换为大写
//str_replace(' ', '-',)所有空格替换为-
}
}
return $headers; //返回前key前5个字符是HTTP_的数组
//return $_SERVER; //返回_SERVER数组
}

Are there any alternatives to PHP sessions?Apr 29, 2025 am 12:36 AMAlternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
