For web developers, installing PHP is an essential step, and PHP 5.6 version is the version currently used by most websites. This article will introduce how to download and install PHP5.6 in Windows systems.

Find the line "PHP 5.6.x VC11 x64 Non Thread Safe" and click the download link to download.

2. Right-click on the php.ini file and select "Edit" to open the file.
3. In the opened php.ini file, find the "extension_dir" field, uncomment and set the value to the directory where the PHP extension module is located. In this example, set it to "extension_dir = "c:\php\ext"" (note that "c:\php" is changed to the path of your PHP folder).
4. In the opened php.ini file, find "extension=mysqli" and "extension=openssl", uncomment and save.

Make changes as follows:

AddType application/x-httpd-php .html

4. Add the following code at the end of the code:

DirectoryIndex index.html index.php

5. Save and exit httpd .conf file.

Step 4: Test PHP
