PHP and Ajax: Integrating third-party Ajax libraries

Integrating third-party Ajax libraries in PHP can enhance web page interactivity. Simply load the library and set options to integrate. Using libraries like jQuery, developers can asynchronously fetch dynamic content from the server and populate it into HTML elements, enabling efficient and user-friendly applications.

PHP and Ajax: Integrating third-party Ajax libraries

Introduction

Ajax (Asynchronous JavaScript and XML) is a powerful technology that allows developers to update parts of a web page without reloading the entire page. PHP is a popular server-side language that can be used to integrate Ajax libraries.

Integrating third-party Ajax libraries

To integrate a third-party Ajax library, you need to load the library and set some options. For example, to integrate jQuery, add the following code:

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

Practical case: Using Ajax to get dynamic content

The following code demonstrates how to use Ajax to get dynamic content from the server , the content will be populated into the HTML element:

<?php
// 建立数据库连接
$db = new PDO('mysql:host=localhost;dbname=ajax_demo', 'root', '');

// 获取动态内容
$results = $db->query('SELECT * FROM news');

// 编码数据为 JSON
$data = json_encode($results->fetchAll(PDO::FETCH_ASSOC));

// 返回 JSON 响应
header('Content-Type: application/json');
echo $data;
?>

<script>
// 使用 jQuery 向服务器发送 Ajax 请求
$.ajax({
    url: 'ajax_get_news.php',
    method: 'GET',
    success: function(data) {
        // 填充 HTML 元素
        $('#news-container').html(data);
    }
});
</script>

Note: Please make sure to place ajax_get_news.php in the same directory as the HTML file.
