How to become familiar with php environment construction

Before we learn and use PHP, we need to set up a PHP environment first. However, for beginners, this can be a very challenging process. This article will provide you with some useful suggestions and tips to help you get familiar with setting up a PHP environment more easily.

1. What is PHP environment?

First let us understand what the PHP environment is. Simply put, a PHP environment is a system in which components such as a PHP parser, database, and Web server are installed and configured on a server.

2. Choose an operating system that suits you

Before building a PHP environment, you need to choose an operating system that suits you. Generally speaking, Windows, Mac and Linux are common operating systems. Which operating system you choose depends on your personal preferences and practical needs.

Of course, Linux is the most popular server operating system because it is stable, secure and free, and it offers a wide variety of free software solutions.

3. Understand the PHP version

Before installing PHP, you need to know the PHP version you want to use. If your application or website requires a specific PHP version, you must install that version. However, if you are new to PHP, it is recommended that you use the latest version of PHP as it usually contains more features and better performance.

4. Download PHP

Downloading is the first thing to do before completing the environment setup. Now, you can download PHP from the official website or other reliable websites. You can find Windows and Linux versions on the Select PHP version page.

For Windows, you can use software packages such as XAAMP, WAMP or EasyPHP, which integrate components such as PHP, web server and database, which can greatly simplify the installation and configuration process. For Linux/UNIX operating systems, you need to download and install the binary file or source code corresponding to PHP, compile and install it.

5. Install the Web Server

Installing the web server is very important because it distributes web requests to the PHP interpreter and sends them back to the client, thereby sending the web application to the client. . Apache is the most widely used web server, but other popular web servers such as NGINX can also be used.

6. Install the database

Usually, web applications need to interact with the database to store and retrieve data. MySQL is one of the most commonly used databases, MSSQL and Oracle are also popular. You can download and install the database on the official website.

7. Configure PHP

After the installation is completed, you need to configure PHP. Use an editor to open the php.ini file for configuration. It may be necessary to disable some PHP extensions or enable others to meet your application needs. You can also configure settings such as PHP's error reporting and logging.

8. Test PHP installation

After completing the above steps, you need to test whether the installation was successful by creating a PHP file and accessing it in a web browser.

Create a PHP file on your web server and save the following code as "myphp.php":

phpinfo();
? >

Now, use a web browser to access the file. If you see a bunch of information, including the PHP version, congratulations, you have successfully installed and configured the PHP environment.

The above are the basic steps for establishing a PHP environment.
