How to install PHP extension in Windows system

For PHP developers, installing extensions is a very critical step, because this can add various applications to PHP to solve various problems. In this article, we will explain how to install PHP extensions in Windows systems to add more functionality to your PHP applications.

1. Download PECL extension

PECL is the abbreviation of PHP Extension Library and Application Library Center. It is a community-driven project consisting of extensions developed by PHP users. The official website of PECL is www.pecl.php.net. Download the PECL extension from this website. PECL extensions are usually provided as zip archives, so you will need to unzip them after downloading.

2. Confirm the PHP extension directory

Before installing the PECL extension, you need to confirm whether the PHP extension directory is correctly set in the INI configuration of PHP. Find the php.ini file from the PHP installation directory and open the file with an editor. Search the extension_dir keyword in the file, find the corresponding line, and confirm whether the extension directory is in the correct location. If extension_dir is set incorrectly, you need to change that setting so that PHP can load the PECL extension correctly.

3. Installing Pecl extension

The installation process of Pecl extension is very simple. You only need to perform the following steps:

a. Open the command prompt, And switch to the PHP installation directory.

b. Run cmd.exe, enter cd C:\xampp\php (the location of the folder is adjusted according to your own installation path)

c. Run php.exe -r “print_r (get_loaded_extensions())" Check the list of currently loaded extensions.

d. Use the CD command to enter the ext folder in the PHP installation directory. This folder is where all PHP extensions are saved.

e. Enter the command at the current command line interface cursor position: pecl install extension name. For example: pecl install redis

f. If you have not installed PHP in the VS environment in advance, you will be asked to select the version of the VS environment; if you already have a VS environment, you will compile and install it.

g. You may need to pay attention to entering some information during the compilation process. For example, you need to enter additional options when turning on the Opcache extension.

4. Confirm that the extension is installed

After the PECL extension installation process is completed, you need to confirm in the php.ini file whether the new extension has been loaded successfully. Find the php.ini file and open it with an editor. Find the settings for the dynamic extension library in the file and see if the new extension name has been added to it. If the new extension name has been added to the php.ini file, the new extension has been loaded successfully.

With this foundation, you can start enhancing your PHP applications with new PECL extensions.
