PHP Installing a PHP environment on Windows


HTTP services normally run on port 80, but if you have some application installed like Skype which also utilizes port 80 then it won't start. In that case you need to change either its port or the port of the conflicting application. When done, restart the HTTP service.

Download, Install and use WAMP

WampServer is a Windows web development environment. It allows you to create web applications with Apache2, PHP and a MySQL database. Alongside, PhpMyAdmin allows you to manage easily your databases.

WampServer is available for free (under GPML license) in two distinct versions : 32 and 64 bits. Wampserver 2.5 is not compatible with Windows XP, neither with SP3, nor Windows Server 2003. Older WampServer versions are available on SourceForge.

WampServer versions:

Providing currently:

  • Apache: 2.4.18
  • MySQL: 5.7.11
  • PHP: 5.6.19 & 7.0.4

Installation is simple, just execute the installer, choose the location and finish it.

Once that is done, you may start WampServer. Then it starts in the system tray (taskbar), initially red in color and then turns green once the server is up.

You may goto a browser and type localhost or to get the index page of WAMP. You may work on PHP locally from now by storing the files in <PATH_TO_WAMP>/www/<php_or_html_file> and check the result on http://localhost/<php_or_html_file_name>

Install PHP and use it with IIS

First of all you need to have IIS (Internet Information Services) installed and running on your machine; IIS isn't available by default, you have to add the characteristic from Control Panel -> Programs -> Windows Characteristics.

  1. Download the PHP version you like from and make sure you download the Non-Thread Safe (NTS) versions of PHP.
  2. Extract the files into C:\PHP\.
  3. Open the Internet Information Services Administrator IIS.
  4. Select the root item in the left panel.
  5. Double click on Handler Mappings.
  6. On the right side panel click on Add Module Mapping.
  7. Setup the values like this:
Request Path: *.php   
Module: FastCgiModule  
Executable: C:\PHP\php-cgi.exe  
Name: PHP_FastCGI  
Request Restrictions: Folder or File, All Verbs, Access: Script
  1. Install vcredist_x64.exe or vcredist_x86.exe (Visual C++ 2012 Redistributable) from

  2. Setup your C:\PHP\php.ini, especially set the extension_dir ="C:\PHP\ext".

  3. Reset IIS: In a DOS command console type IISRESET.

Optionally you can install the PHP Manager for IIS which is of great help to setup the ini file and track the log of errors (doesn't work on Windows 10).

Remember to set index.php as one of the default documents for IIS.

If you followed the installation guide now you are ready to test PHP.

Just like Linux, IIS has a directory structure on the server, the root of this tree is C:\inetpub\wwwroot\, here is the point of entry for all your public files and PHP scripts.

Now use your favorite editor, or just Windows Notepad, and type the following:

header('Content-Type: text/html; charset=UTF-8');    
echo '<html><head><title>Hello World</title></head><body>Hello world!</body></html>';

Save the file under C:\inetpub\wwwroot\index.php using the UTF-8 format (without BOM).

Then open your brand new website using your browser on this address: http://localhost/index.php
