jQuery/Ajax/PHP/Json 的一个综合例子
jQuery 是一个优秀的 Javascript 框架,对 js 进行了优秀的包装,提供了许多方便的功能。jQuery 对 ajax 的包装也堪称优秀。
jQuery 可以以 json 文件传输协议来传输数据(类似 xml,而且大有取代 xml 的趋势),而网站后台代码必须与之配合使用。PHP 是用 json_encode 函数来对返回的数组数据进行编码的,但这个函数只有 PHP5.2版本以上才支持。
从网上找到一个 json 的操作类,本人在 PHP4.4.7 版本下测试通过。本人还建了个函数 function my_json_encode($phparr),使代码兼容 PHP5.2 以上版本。
示例代码(包括 json 的类包软件)可以在以下网址下载:http://www.BkJia.com/uploadfile/2012/0221/20120221090101730.rar
以下是全部代码:
PHP 文件 ajax_json.php:
//$arr = $_POST; //若以$.get()方式发送数据,则要改成$_GET.或者干脆:$_REQUEST
$arr = $_REQUEST;
$arr['append'] = '测试字符串';
//print_r($arr);
$myjson = my_json_encode($arr);
echo $myjson;
function my_json_encode($phparr)
{
if(function_exists("json_encode"))
{
return json_encode($phparr);
}
else
{
require_once 'json/json.class.php';
$json = new Services_JSON;
return $json->encode($phparr);
}
}
?>

This tutorial demonstrates how to efficiently process XML documents using PHP. XML (eXtensible Markup Language) is a versatile text-based markup language designed for both human readability and machine parsing. It's commonly used for data storage an

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
