How to install and configure the php environment under windows

With the widespread application of PHP in Web development, more and more developers need to build a PHP environment on Windows systems. For your convenience, this article will introduce the steps to install PHP under Windows system.

1. Download the PHP installation package

First, you need to download the PHP Windows installation package from the PHP official website. On the download page, you need to select the corresponding download link and download the binary file with the corresponding number of bits according to the version of your Windows system.

2. Install Web server software

Before installing PHP, you need to install Web server software, such as Apache or IIS. Here we take Apache as an example. You can download and install it from the Apache official website.

3. Configuring Apache

After the installation is complete, you need to open the Apache configuration file httpd.conf and find the following line: #LoadModule php7_module modules/libphp7.so, remove the previous comment symbols. Then add the following configuration information to the file:

AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
LoadModule php7_module “c:/php/php7apache2_4.dll”
PHPIniDir “c:/php”

These configurations will tell Apache to use the PHP interpreter when opening PHP files and set the path to the PHP interpreter.

4. Install PHP

Extract the downloaded PHP installation package to a directory, such as C:\php.

5. Configure PHP

Open the php.ini-development file in the PHP directory and rename it to php.ini. In this file, set the following directives:

extension_dir = "C:\php\ext"

Note that the path of this extension_dir should be consistent with your actual PHP extension directory.

6. Testing PHP

After installation and configuration are completed, you can access a page containing PHP code through the browser, such as index.php. If configured correctly, you can see the PHP code running normally.

7. Other issues

If you find that the PHP code is not running properly, you can check the following aspects:

• Check whether Apache's configuration file is correct.
• Check whether the PHP configuration file is correct.
• Check whether the permissions of the PHP file are correct.

Summary:

The above are the steps to install PHP under Windows system. Although the installation may sometimes fail for some reasons, the installation steps themselves are very simple. As long as you follow the above steps one by one, you can quickly complete the work of setting up a PHP environment.
