What environment should I install to write php files?

PHP (Hypertext Preprocessor) is a widely used server-side scripting programming language. It was developed for web development to dynamically generate web content. Before proceeding with PHP programming, we need to install an appropriate development environment, including a web server and PHP parser, etc. This article will introduce how to install an environment suitable for writing PHP files.

Step One: Install the Web Server

Before proceeding with PHP programming, we need to install the Web server. Here we recommend using the Apache server, which is a free and open source web server software that is easy to install and configure. The specific installation method is as follows:

1. Download Apache server

Go to the Apache official website (https://httpd.apache.org/) to download the latest version of the Apache server software.

2. Install Apache server

After the download is completed, we can run the downloaded installation program and select the installation path and configuration information according to the prompts.

3. Start the Apache server

After the installation is complete, we need to start the Apache server and enter "http://127.0.0.1/" or "http ://localhost/" to see the home page of the Apache server.

Step 2: Install the PHP parser

After installing the web server, we need to install the PHP parser, which converts PHP code into executable instructions. The specific installation method is as follows:

1. Download PHP parser

Go to the PHP official website (https://www.php.net/downloads) to download the required version of PHP parser device.

2. Install the PHP parser

After downloading the parser, run the installation program and select the installation path and configuration information according to the prompts.

3. Configure the Apache server to support PHP

Open the configuration file "httpd.conf" of the Apache server and add the following content at the end of the file:

LoadModule php7_module "C:\php\php7apache2_4.dll"
AddHandler application/x-httpd-php .php
PHPIniDir "C:/php"

where "C:/php" is your PHP The installation path of the parser.

4. Restart the Apache server

After the configuration is completed, we need to restart the Apache server and enter "http://127.0.0.1/" or "http ://localhost/" to see the Apache server homepage that already supports PHP.

Step 3: Write PHP files

After successfully installing the Apache server and PHP parser, we can start writing PHP files. Open a code editor (such as Notepad, etc.) and write a "hello world" PHP file, as shown below:

<?php
echo "Hello, World!";
?>

Save this code as a file with a ".php" extension. The file name can be arbitrary Pick. After saving, place the file in the root directory of the Apache server. The "htdocs" folder is the root directory. Enter "http://127.0.0.1/filename.php" or "http:// localhost/filename.php" to see the output "Hello, World!".

Summary:

Through the above steps, we can successfully install an environment suitable for writing PHP files. It should be noted that when writing PHP files, you must follow the PHP syntax specifications, otherwise it will not execute properly. In addition, for beginners, it is recommended to learn some basic PHP syntax and applications first, and then gradually deepen and improve their PHP programming level.
