What are the advantages of PHP and MySQL? Why is it so popular?

As one of the most commonly used technologies in web development, PHP and MySQL are favored because of their collaborative advantages. PHP is a language widely used for server-side script programming, and MySQL is an open source relational database system. The combination of the two can realize the development of dynamic web pages. Next, we will introduce the advantages of PHP and MySQL respectively, and demonstrate the powerful effect between them through specific code examples.

First let’s look at the advantages of PHP:

1. Easy to learn and use: PHP syntax is simple, flexible, easy to learn and use, and is suitable for beginners to get started quickly.
2. Cross-platform: PHP supports multiple operating systems, including Windows, Linux and macOS, enabling cross-platform application development.
3. Powerful function extension: PHP has a wealth of built-in functions and third-party extension libraries, which can meet various needs, such as text processing, image processing, network communication, etc.

The following is a simple PHP code example that implements a simple web page counter:

Then let’s look at the advantages of MySQL:

1. Stable and reliable: MySQL is a mature relational database management system with high stability and safe and reliable data.
2. Powerful performance: MySQL can handle large-scale data storage and query, has efficient read and write performance, and is suitable for applications of all sizes.
3. Flexibility: MySQL supports a variety of data types and query statements, and can meet various data processing needs, such as addition, deletion, modification, and query operations.

The following is a simple MySQL code example to create a user table named users:

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(50) NOT NULL,
    email VARCHAR(50) NOT NULL
);

Finally, we will show the combination of PHP and MySQL Application to implement a simple user registration function:

connect_error) {
    die("连接失败：" . $conn->connect_error);
}

$name = "Alice";
$email = "alice@example.com";

$sql = "INSERT INTO users (name, email) VALUES ('$name', '$email')";

if ($conn->query($sql) === TRUE) {
    echo "新记录插入成功";
} else {
    echo "Error: " . $sql . "
" . $conn->error;
}

$conn->close();
?>

The above are the advantages and specific code examples of PHP and MySQL. The collaborative advantages between them make Web development more efficient, flexible and reliable, so they are highly praised. favor. I hope this article can help readers better understand and use PHP and MySQL.
