Thank you for reporting the issue. We are looking into it.

@Jen7714 - I see there were updates to Php.exe https://github.com/Azure/app-service-announcements/issues/108. Looks like php.exe is not on the path anymore in Azure

[pragnagopa]

We have identified the root cause. This is a regression and we are working on the fix. As a temporary workaround, please follow instructions here: https://github.com/Azure/azure-functions-host/wiki/Using-a-custom-version-of-Python and copy Download PHP 5.6 (or whichever version you want) from here https://windows.php.net/downloads/releases/php-5.6.36-Win32-VC11-x86.zip instead of python to site\tools.

@pragnagopa
Executing where php.exe outputs D:\Program Files (x86)\PHP\v5.6\php.exe, so PHP.exe is included in PATH.

And I tried the workaround (deploying PHP runtime to D:\home\site\tools ), but nothing is changed.

@hihorika - Yes. When you run the command from kudu console it is available. But is removed when function app is loaded.
I have verified the workaround of copying php to site\tools works. Can you please share you app name either here or indirectly?

[hihorika]

@pragnagopa I succeeded to work php function using the workaround you mentioned.
Thanks!

And I hope that php function works without the workaround.
