The key to configuring a PHP development environment is to select the toolchain, install the necessary components and ensure normal collaboration. 1. Install the PHP interpreter and commonly used extensions. It is recommended that novices use XAMPP, WAMP or MAMP one-click integration packages, or manually install and enable php-mbstring, php-curl and other extensions through brew, apt, etc.; 2. Build a local development server, and you can use the integration package's own Apache, PHP built-in server (such as php -S localhost:8000) or Nginx PHP-FPM. It is recommended that novices use the built-in server first; 3. Configure database connections, such as using MySQL in the integration package, and test through PDO or mysqli connection; 4. Use IDE to improve efficiency, recommend VS Code, PhpStorm, etc., and configure code prompts and debugging tools to improve the development experience.

It is actually not difficult to configure a PHP development environment, but it may be a bit fascinating for beginners. The key is to choose the toolchain, install the necessary components, and ensure that they can work together properly. Let’s start from several common needs and talk about how to build it step by step.

1. Install the PHP interpreter and basic extensions

The first thing to have is PHP itself. You can choose to install it directly on the local system, or use a virtual machine or Docker. It is recommended that beginners use XAMPP or WAMP (Windows) or MAMP (Mac). These integration packages include Apache, MySQL and PHP, which can save you a lot of trouble when installing with one click.

If you prefer manual control version, you can use:

• macOS : brew install php
• Ubuntu/Debian : sudo apt install php php-cli php-mysql
• Windows : Download the official PHP package and configure environment variables

Remember to check whether commonly used extensions are enabled, such as php-mbstring , php-curl , php-gd , etc. Many frameworks rely on these.

2. Build a local development server

To write PHP, you need to run to see the effect, so you need to have a local server. There are several ways:

• Use XAMPP/WAMP/MAMP with Apache
• Use PHP built-in development server: After entering the project directory, run php -S localhost:8000
• Advanced users can consider using Nginx PHP-FPM

It is recommended that novices try using the built-in server first, it is simple without changing the configuration. For example, you wrote an index.php file and execute:

 php -S localhost:8000

Then the browser opens http://www.miracleart.cn/link/f74d6ef882234fd34400a296b1da6149 and you will see the page.

3. Configure database connections (such as MySQL)

Most PHP projects require database support. If you are using the integration package, MySQL is already included. After starting the service, you can manage the database through phpMyAdmin or log in on the command line:

 mysql -u root -p

PHP is generally used to connect to databases with PDO or mysqli. Let's give a simple example:

 <?php
$host = &#39;127.0.0.1&#39;;
$db = &#39;test_db&#39;;
$user = &#39;root&#39;;
$pass = &#39;&#39;;
$charset = &#39;utf8mb4&#39;;

$dsn = "mysql:host=$host;dbname=$db;charset=$charset";
try {
    $pdo = new PDO($dsn, $user, $pass);
} catch (\PDOException $e) {
    throw new \PDOException($e->getMessage(), (int)$e->getCode());
}
?>

If you can't connect, check whether the database service is running, whether the username and password are correct, and whether you have remote access (if it is a remote database).

4. Use IDE to improve efficiency

Although you can write PHP with Notepad, it will be much easier to use a good editor. A few commonly used ones are recommended:

• VS Code : Free, lightweight, and rich plug-ins (such as PHP Intelephense)
• PhpStorm : powerful but expensive, suitable for professional developers
• Sublime Text/Atom : Not bad, but not as popular as the first two

After configuring the code prompts, debuggers (Xdebug), and syntax highlighting, you will find that writing code is much faster.

Basically that's it. The whole process seems to have many steps, but in fact each step is not complicated. It is easy to ignore certain details, such as the wrong path, the extension is not opened, the service is not started, etc. Don't worry if you encounter problems, check the logs and Google can basically solve them.
