Everybody knows that IIS FastCGI is a great way to run PHP applications on IIS. We've been making great

lol, are you sure "everyone knows"? Seems like no one knows...

# Jonathan Puddle said on October 12, 2007 7:58 AM:

That said, I am really thrilled to try this out. Good work!

Yes, I'd say a lot of people know :) There has been a great deal of talk and excitement around this, but this post is really about the straight facts to help people get started.

I have no problem running applications such as phpBB with php5ISAPI.dll ? Can you tell me why fast cgi is better?

# Mike Volodarsky said on October 27, 2007 2:01 AM:

Hi John,

The main reason why ISAPI is not an adequate solution is the lack of thread safety in many popular PHP extensions.  The PHP core itself is thread safe, and so are some of the extensions, so its possible that some applications will work correctly in the ISAPI environment.  However, many production environments do experience instability with the ISAPI.  You can read more about this in my original post: http://mvolo.com/blogs/serverside/archive/2006/09/29/Making-PHP-rock-on-Windows_2F00_IIS.aspx.

Thanks,

Mike

I found out about this my just searching through the 2003 Updates Database. I was really surprised to see this option for IIS, now I can work more efficiently instead of having to run Linux or Apache! This is really cool. Great way to mix up scripting and application on one server instead of many.

Some 6 months ago I tried FastCGI in Vista 64-bit. It was quite painful; I think I ultimately got it to work... or almost to work, but I wouldn't want to try it again. Is PHP / FastCGI is as mature as x86 version?

# Antonio said on January 6, 2008 3:06 PM:

Several PHP Apps required Apache "mod_rewrite". We can read about several PHP Apps at http://www.iis.net/phpapps, but not a word about this requirement. I read about some 3rd solutions like "IIS Mod-Rewrite Pro" that we have to buy. There is a Microsoft Solution? I don't want to use in our Production Server a 3rd solution but how can we use Fastcgi/PHP5 with some real Apps like DRUPAL without "mode_rewrite"?

Should I remove or disable ISAPI before enabling FastCGI? I'm running IIS7 on Vista Business.

# Mike Volodarsky said on March 6, 2008 8:52 PM:

You dont need to do that, although, it is recommended - it can help avoid creating confusing handler mapping configuration where you may be accidentally using Isapi instead of FastCGI and visa versa.

FastCGI is a more reliable way to host PHP applications so you should theoretically never install the ISAPI. If you follow the installation instructions in one of the linked articles, it will walk you through installing PHP with FastCGI without using the PHP Windows installer which may generate ISAPI configuration.

Thanks,

Mike

Mr  Program Manager  you have so many errors in links and text that I doubt IIS7 will work under your "management" Server 2006 what that means dude?

# John Wielki said on March 22, 2008 1:00 PM:

I just installed Vista SP1. I want to enable PHP, using the instructions on IIS.net. The instuctions say that FastCGI is included in SP1. When I go into IIS manager and click "Handler Mappings", then click "add module mapping" (which is in the instructions), the dropdown list of modules does not contain an entry for fastCGI. I have rebooted a couple of times, and Vista says that its version is SP1, but I don't see the fastcgi module. Am I doing something wrong?

# Mike Volodarsky said on March 24, 2008 10:39 AM:

Hi mumu,

Thanks for spotting the "Windows Server 2006" typo, I fixed it.  All other links are working - what other errors did you see?

As far as your other concern, IIS 7.0 is "working" pretty well so far, be sure to try it :)

Thanks,

Mike

Thanks for the efforts to get PHP and IIS7 to be good neighbors; I am trying to get PHP 5.2.3 ro work on IIS7 I still have an issue getting PHP to work on my Vista Business installation - using the fastCGI or the IIS-ISAPI modules as suggested by bill's blog on IIS.net. From localhost i call mytest.php, - then the page just hangs... - and no IIS error apge or HTTP40X.X error returns any suggestions?

# Mike Volodarsky said on April 30, 2008 6:22 PM:

Coolhand,

Can you get a simple hello world php script working, or does it also hang?

Be sure that you are creating the FastCGI mapping to php-cgi.exe, not php.exe. If you configure a random process that doesnt support FastCGI to be used with FastCGI, it may exibit hanging.

If it doesnt help, post on forums.asp.net and we'll help you more.

Thanks,

Mike
