第一个文件
<?php require('../class/connect.php'); //引入数据库配置文件和公共函数文件 require('../class/db_sql.php'); //引入数据库操作文件 require('../data/dbcache/class.php'); //引入栏目缓存文件 $link=db_connect(); //连接MYSQL $empire=new mysqlquery(); //声明数据库操作类 $editor=1; //声明目录层次 $ids=array(); $ids=explode(",",$_GET['id']); foreach($ids as $id){ $sql=$empire->query("select * from {$dbtbpre}ecms_yue where id = '".$id."'"); //查询数据表 require('template/yue.temp.php'); //导入模板文件 } db_close(); //关闭MYSQL链接 $empire=null; //注消操作类变量 ?>
第二个文件
<?phpwhile($r=$empire->fetch($sql)) //循环获取查询记录{?> { "songid": <?=$r[地址]?>, },<?php}?>
上面是一段 php 循环 代码 2个文件
http://localhost:82/e/song/?id=1322
连接是这样! 程序是帝国cms
在数据表中有个 音乐库 ! 下有2个 字段 歌手 和 标题
=$r[歌手]?> =$r[歌手]?>
通过访问上面那个个 地址 来获取 百度 音乐地址
歌手 和 标题 直接 通过ID /?id=1322 向帝国cms 来获取 歌手 和 标题的值
下面我模拟下 获取方式
<?phpwhile($r=$empire->fetch($sql)) //循环获取查询记录{?> { "songid": <?=$r[地址]?>, "songurl": 然后在这输出音乐地址, },<?php$url='http://box.zhangmen.baidu.com/x?op=12&count=1&mtype=2&title=<?=$r[歌手]?>$$<?=$r[歌手]?>'; $lines_string=file_get_contents($url); eregi('<title>(.*)</title>', // 抓去前面部分 eregi('<title2>(.*)</title2>', // 抓取后面部分 就是MP3的文件名 $lines_string,$title); echo htmlspecialchars($title[0]); }?> // 注 要 去掉百度的音乐连接 就是不要百度的 !要其他站的 ! // 百度的的后面多个 乱码 播放不了! // 在去掉wma 格式!就要MP3 的! 随机输出1条 数据! // 只输出一条 页面刷新几次 输出结果也换换 !地址有多的话 最好把歌词ID 也菜下来
上面代码 我乱写的! 乱写的!
我不会写PHP 额! 只能来这了!

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
