Hi, If you are hosting PHP on IIS6 the best bet is to use IIS FastCGI with Non thread safe VC6 build of PHP. You can use the below resources to configure PHP on IIS6: 1. http://learn.iis.net/page.aspx/247/using-fastcgi-to-host-php-applications-on-iis-60/ 2. http://www.php.net/manual/en/install.windows.php You can also use Microsoft Web Platform Installer and everything will be configured automatically. Details at http://blogs.iis.net/donraman/archive/2009/10/07/installing-php-on-windows.aspx. Windows bits are available at windows.php.net. So use that to download PHP. PHP5.2.13 is the latest build and hence using it is a good idea because there will be good amount of bug fixes and it is supported by community too meaning if you find a bug, you can file it on bugs.php.net and get it fixed. Any other version will require you to move to 5.2.13 and see if the problem is re-occurring with it also. Thanks, Don. -----Original Message----- From: Todd Oberly [mailto:taoberly@xxxxxxxxxxxxxx] Sent: Friday, April 02, 2010 6:06 PM To: php-windows@xxxxxxxxxxxxx Subject: Windows binaries Hi, Does anyone know why there isn't a VC9-compiled binary for PHP 5.2.13 ? The PHP application I'm using isn't currently compatible with PHP 5.3.x, so I need a 5.2 build, but it will also be running in IIS 6. What is my best option? Use the VC6 x86 Thread Safe build of 5.2.13, use the older VC9 x86 Thread Safe build of 5.2.12, or use something else? (BTW, what is the difference between the Windows binaries at www.php.net vs. the binaries from windows.php.net ? GCC builds vs. VS?) Do the security fixes in 5.2.13 always win out over stability? (This feels like an FAQ, but I couldn't find anybody else asking the same question...) Thanks for your insights!
