I currently have PHP 5.3.1 installed on a Windows 2003 Server (under IIS).
It is running as ISAPI currently.
phpinfo() shows this particular build:
PHP Extension Build API20090626,TS,VC9
On the php windows download page here:
They show these different options for installing the latest version:
PHP 5.3 (5.3.8)
VC9 x86 Non Thread Safe (2011-Aug-23 12:26:18)
- Zip [14.93MB]
- Installer [38.31MB]
- Debug Pack [7.91MB]
VC9 x86 Thread Safe (2011-Aug-23 12:01:10)
- Zip [15.06MB]
- Installer [38.43MB]
- Debug Pack [8.25MB]
Which of these versions is the correct version that I should upgrade to, given my current version?
How do I actually do the update? Once installed, how do I point IIS to use the new version of PHP and not the old one? I assume I can leave the old one in place (to be safe) in case I can't get the new one working, so I'd rather not delete it unless it is absolutely necessary.
I'm also open as to running this as FastCGI instead of ISAPI, if that would result in better and more stable performance. If FastCGI is a better way to go,
Thanks for help on this!
