PHP and MySQL are called the golden partners of web development because of their perfect cooperation and complementary advantages. PHP, as a popular server-side scripting language, can handle various dynamic web development needs; while MySQL is an open source relational database management system that provides efficient data storage and retrieval services. With the combination of PHP and MySQL, developers can easily build powerful, high-performance web applications.

3. Combination of PHP and MySQL
Through the combination of PHP and MySQL, developers can realize dynamic storage and retrieval of data, realizing the connection between web applications and databases connect. The following is a simple code example to illustrate the combination of PHP and MySQL:
<?php // 连接MySQL数据库 $servername = "localhost"; $username = "root"; $password = ""; $dbname = "test"; $conn = new mysqli($servername, $username, $password, $dbname); // 检查连接是否成功 if ($conn->connect_error) { die("连接失败: " . $conn->connect_error); } // 查询数据库中的数据 $sql = "SELECT id, name, age FROM users"; $result = $conn->query($sql); // 输出查询结果 if ($result->num_rows > 0) { while($row = $result->fetch_assoc()) { echo "id: " . $row["id"]. " - 姓名: " . $row["name"]. " 年龄: " . $row["age"]. "<br>"; } } else { echo "0 结果"; } // 关闭数据库连接 $conn->close(); ?>
The above code demonstrates using PHP to connect to the MySQL database, query user information in the database, and then output the query results to the web page. In this way, developers can achieve dynamic display and interaction of data, providing users with a richer and interactive web experience.
To sum up, PHP and MySQL, as golden partners in web development, have their own advantages. When used together, they can achieve efficient, stable and secure web application development. Developers can choose appropriate technologies and tools based on actual needs, make reasonable use of the characteristics of PHP and MySQL, and create web applications that satisfy users.
