I came close to giving up on migrating web sites from Windows Server 2019 Datacenter to Windows Server 2022 Datacenter under Azure as I couldn't get PHP to work.
- Web Platform Installer in IIS hasn't installed anything successfully! It told me that it hadn't installed PHP when it had at least installed it partially.
- I therefore installed PHP Manager for IIS from a download as well as URL Rewrite.
- Using PHP Manager to get phpinfo crashed FastCGI and I couldn't seem to solve the issue. Eventually, I found a suggestion that you should run
.\php.exe -info
in PowerShell from the PHP installation directory. This revealed an issue with the Visual C++ Redistributable, solved by downloading and installing:
Microsoft Visual C++ Redistributable Latest Supported Downloads
I offer this in case others hit the same problem.
