How to install and configure PHP on Windows

When developing web pages, PHP is usually an essential programming language. However, in order for PHP to run properly, we need to install and configure the corresponding software on the server.

This article will introduce how to install and configure PHP on the Windows operating system so that you can easily develop web pages.

1. Download PHP

First, we need to download the corresponding compressed package from the PHP official website. Open the official website (https://www.php.net/downloads.php), select "Windows downloads" on the download page and select the corresponding version, such as PHP 8.0.0. Then, select the "VC15 x64 Non Thread Safe" version. Once the download is complete, unzip it to the folder where you want to install PHP.

2. Install Apache

Before installing PHP, we need to install the Apache server first. Visit the Apache official website (https://httpd.apache.org/) to download the corresponding version, such as Apache 2.4.46. After the download is complete, run the installation file and follow the instructions to install.

After the installation is complete, open the Apache configuration file httpd.conf. This file is usually located in the conf folder under the installation directory. Find the following two lines of code and uncomment them (that is, remove the "#" in front):

LoadModule php_module "path/php7apache2_4.dll"
AddHandler application/x-httpd-php .php

It should be noted that the path should be the path pointing to the php7apache2_4.dll file in the bin folder under the PHP installation directory.

3. Configure PHP

Find the php.ini-development file in the PHP directory, copy it and rename it to php.ini. Then, open the php.ini file and find the following lines of code:

;extension_dir = "ext"
;extension=mysqli

Remove the comments from these two lines of code and replace The "ext" after extension_dir is changed to the path of the ext folder in the PHP installation directory.

Then, copy and rename the php.ini-recommended file in the PHP installation directory to php.ini, and open the php.ini file again. Find the following two lines of code:

;display_startup_errors = On
;display_errors = On

Change the value of these two lines of code to Off, that is:

display_startup_errors = Off
display_errors = Off

4. Test PHP

In the htdocs folder in the Apache installation directory, create a file named test.php. Enter the following code in the test.php file:

Save and close the test.php file. Then, use your browser to access the address where the test.php file is located (for example, http://localhost/test.php). If you see the configuration information of PHP, it means that PHP is installed and running normally.

5. Summary
