Understand commonly used PHP web server software

Explore commonly used software for PHP web servers

With the rapid development of the Internet, PHP has become a very popular programming language. The PHP language has the advantages of being easy to learn, high development efficiency, and cross-platform, so it is widely used in the development of various Web applications. In the process of building a PHP server, it is very important to choose suitable software.

This article will introduce some commonly used PHP web server software and provide specific code examples.

1. Apache
   Apache is an open source web server software with the characteristics of stability, reliability and excellent performance. It supports multiple operating systems, such as Windows, Linux, etc., and is perfectly compatible with PHP. The following is a simple Apache configuration example:

<VirtualHost *:80>
    ServerName mydomain.com
    DocumentRoot /path/to/mydomain
    <Directory /path/to/mydomain>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
    ErrorLog /path/to/mydomain/error.log
    CustomLog /path/to/mydomain/access.log combined
</VirtualHost>

2. Nginx
   Nginx is a high-performance web server, especially suitable for handling high concurrent requests. Compared with Apache, Nginx has lower resource consumption and faster response time. The following is a simple Nginx configuration example:

server {
    listen 80;
    server_name mydomain.com www.mydomain.com;
    root /path/to/mydomain;
    index index.php;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ .php$ {
        include fastcgi_params;
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
    }
}

3. PHP-FPM
   PHP-FPM (FastCGI Process Manager) is a tool for managing PHP processes. It works with web servers such as Nginx or Apache to distribute PHP's task of processing requests to multiple PHP-FPM processes through the FastCGI protocol. The following is a simple PHP-FPM configuration example:

[www]
user = www-data
group = www-data
listen = /var/run/php/php7.4-fpm.sock
listen.owner = www-data
listen.group = www-data
listen.mode = 0660

pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

4. MySQL
   MySQL is a popular relational database management system that can be used with PHP to achieve data storage and Retrieve. The following is a simple MySQL connection example:

<?php
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "mydatabase";

$conn = new mysqli($servername, $username, $password, $dbname);

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

$sql = "SELECT * FROM users";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "Name: " . $row["name"]. " - Email: " . $row["email"]. "<br>";
    }
} else {
    echo "0 结果";
}

$conn->close();
?>

In addition to the software listed above, there are many other PHP web server software to choose from, such as LiteSpeed, Lighttpd, etc. Each software has its own characteristics and applicable scenarios. Choosing the right software based on actual needs is very important for the stability and performance of the website.

To sum up, building a PHP web server requires choosing appropriate software that can provide stable and efficient services. This article provides some commonly used PHP network server software and gives specific code examples. I hope it will be helpful to readers when selecting and configuring server software.
