## Install PHP
-From http://windows.php.net/download, pick **VC9 x86 Non Thread Safe** of the latest PHP version and click "Installer" to download the PHP installer.
+Recently, a handy tool called [PHP Manager for IIS](http://phpmanager.codeplex.com/) has made installation of PHP on Windows easy.
-**NOTE**: We chose the "Non Thread Safe" version because we'll run PHP as a FastCGI process through IIS. FastCGI ensures a single threaded execution environment so thread safety checks are not required. This provides significant performance gains over using the thread safe version of PHP.
-
-Once finished downloading, run the installer to get PHP up and running.
-
-When prompted, select **IIS FastCGI** for the web server setup. When asked for which items to install, expand the Extensions tree and check **LDAP** and **Multi-Byte String**. You'll probably need one or both of these in the future, so it's a safe option to install them. LDAP is required for retrieving data from an Active Directory server, for example.
-
-Now we need to set up Handler Mappings in IIS to support PHP scripts.
-
-Open up Internet Information Services (IIS) Manager and click on the second node that appears on the tree to the left.
-
- * Click Handler Mappings
-
-**NOTE**: If you already see an entry for PHP, continue to "Configure FastCGI in IIS" below.
-
- * Click Add Module Mapping located on the right hand Actions bar
- * Enter ***.php** into the Request path field
- * Select FastCGIModule from the Module dropdown menu
- * Enter **"C:\Program Files (x86)\PHP\php-cgi.exe"** (including the quotes) into the Executable (optional) field
- * Enter **PHP** into the Name field
-
-You can also do the same via the command line. Run these commands if you prefer to do it the CLI way:
-
- C:\windows\system32\inetsrv\appcmd set config /section:system.webServer/fastCGI /+[fullPath='"c:\Program Files (x86)\PHP\php-cgi.exe"']
- C:\windows\system32\inetsrv\appcmd set config /section:system.webServer/handlers /+[name='PHP_via_FastCGI',path='*.php',verb='*',modules='FastCgiModule',scriptProcessor='"c:\Program Files (x86)\PHP\php-cgi.exe"',resourceType='Unspecified']
-
-## Configure FastCGI in IIS
-
-There's some best practice configuration we need to apply to FastCGI so that our websites will run optimally.
+ * [Download PHP Manager for IIS](http://phpmanager.codeplex.com/releases/view/69115)
+ * Run and install to enable PHP Manager support in IIS (make sure it's x86 or x64 depending on your Windows version)
+ * From [http://windows.php.net/download](http://windows.php.net/download), pick **VC9 x86 Non Thread Safe** of the latest PHP version and click "Zip" to download PHP.
- * Click FastCGI Settings in the IIS Manager
- * Click the PHP entry that appears in the list, and click Edit in the right hand Actions panel
- * Look for InstanceMaxRequests and change the value to **10000**
- * Look for ActivityTimeout and change the value to **900**
- * Look for RequestTimeout and change the value to **900**
- * Click the (Collection) field and press the ... button that appears to the right
- * Click Add when the dialog box appears
- * On the right, enter **PHP_FCGI_MAX_REQUESTS** for the entry to the Name field
- * On the right, enter **10000** for the entry to the Value field
-
-Again, like adding the handler mappings, the same procedures can be done using the command line:
-
- C:\windows\system32\inetsrv\appcmd set config -section:system.webServer/fastCgi /[fullPath='"c:\Program Files (x86)\PHP\php-cgi.exe"'].instanceMaxRequests:10000
- C:\windows\system32\inetsrv\appcmd set config -section:system.webServer/fastCgi /[fullPath='"c:\Program Files (x86)\PHP\php-cgi.exe"'].ActivityTimeout:900
- C:\windows\system32\inetsrv\appcmd set config -section:system.webServer/fastCgi /[fullPath='"c:\Program Files (x86)\PHP\php-cgi.exe"'].RequestTimeout:900
- C:\windows\system32\inetsrv\appcmd set config -section:system.webServer/fastCgi /+"[fullPath='"c:\Program Files (x86)\PHP\php-cgi.exe'].environmentVariables.[name='PHP_FCGI_MAX_REQUESTS',value='10000']"

-The [official guide configuring IIS for PHP applications is available](http://learn.iis.net/page.aspx/771/configure-and-optimize-the-microsoft-web-platform-for-php-applications/) for reference.
-
-## Add index.php as default document
+**NOTE**: We chose the "Non Thread Safe" version because we'll run PHP as a FastCGI process through IIS. FastCGI ensures a single threaded execution environment so thread safety checks are not required. This provides significant performance gains over using the thread safe version of PHP.
-This is good practise, so if you browse to http://localhost/silverstripe then it will automatically run index.php. IIS needs to be told which default documents should be checked for when accessing a directory in the URL.
+ * Once downloaded, unpack the contents of the zip to **C:\php**
+ * Open **Internet Information Services (IIS) Manager** and click the server node in the left panel
+ * Go to **PHP Manager**
+ * Click **Register new PHP version**
+ * Enter **C:\php\php-cgi.exe**
+ * Click **Configure error reporting** and choose **Development machine** (change to **Production machine** later if you wish. For now we set to development to test PHP is working)
-To add index.php as a default document:
+If you need to change any PHP settings, you can do so by clicking **Manage all settings** in PHP Manager.
+There is no need to edit C:\php\php.ini any longer, as it can be done from here instead.
- * Open Internet Information Services (IIS) Manager
- * Click your server name on the left when the program opens
- * Double click the **Default Document** icon
- * Verify that index.php doesn't already exist in the file list
- * Click **Add** on the right sidebar to add a new entry
- * Enter **index.php** when the dialog box pops up and hit **OK**
+The first thing you should do is make sure the date.timezone setting is correct, so open **Manage all settings**
+and scroll down to date.timezone and make sure you select your correct timezone.
## Install the SQL Server Driver for PHP

-## Configure PHP
-
-PHP is installed and works with IIS, but the configuration needs a bit of minor tweaking.
-
-Open Windows Explorer. Browse to C:\Program Files (x86)\PHP and open php.ini.
-
-Note: You may need to run Notepad as administrator (right click Notepad.exe and click "Run as administrator"). From inside Notepad, open C:\Program Files (x86)\PHP\php.ini.
-
-First of all, look for **;date.timezone** and replace it with this one (replacing Pacific/Auckland to your timezone if you're not in New Zealand).
-
- date.timezone = Pacific/Auckland
-
-Secondly, look for **display_errors** and **display_startup_errors**. Replace the Off value for each of these with **On**.
-
-Thirdly, PHP has a very low maximum file size of 2 megabytes for file uploads. Look for **post_max_size**, and **upload_max_filesize**. Change 2M and 8M respectively, to **128M**. This is important to allow large uploads from users, such as video. If you feel you don't require as much, change it to **64M** for both, which is a sensible limit.
-
-Again, look for **max_input_time**. Replace the 60 value with **900**. The reason we're doing this is to match the 900 value we set earlier in IIS.
-
-Lastly, there's one FastCGI setting we need to apply, and it's missing in the configuration by default. Look for **fastcgi.impersonate=1** and add this line below it:
-
- cgi.fix_pathinfo=1
-
-SilverStripe sites will email errors to developers which are crucial for debugging. It's also needed for any emails generated by the website. PHP needs to know where your SMTP server is located, and which port it listens on to be able to send emails.
-
-In php.ini, look for this block of code:
-
- [mail function]
- ; For Win32 only.
- ; http://php.net/smtp
- SMTP = localhost
- ; http://php.net/smtp-port
- smtp_port = 25
-
-Make sure that the SMTP and smtp_port are set to your mail server's hostname and port respectively.
-
-That should do it for the PHP configuration.
+ * Copy **php_sqlsrv_53_nts_vc9.dll** to C:\php\ext
+ * Open **PHP Manager** in IIS and click **Enable or disable an extension**
+ * Find the php_sqlsrv extension in the list and right click > Enable
+ * Restart IIS
## Test PHP installation
Now that we've got PHP configured how we want it, let's test that PHP is working correctly.
-First things first, restart IIS using IIS Manager.
-
-Create a new file using Notepad called test.php if you haven't already, inside **C:\inetpub\wwwroot**
-
-Inside the file, add this content:
-
- <?php
- phpinfo();
-
-Open a browser and point it to http://localhost/test.php
+ * Open **PHP Manager** in IIS Manager
+ * Click **Check phpinfo()** and use **Default web site**
You should receive a long page containing PHP configuration information. If you do receive this, PHP has been installed correctly through IIS. Congratulations!
The next part is to install SilverStripe and verify that it works.
