I am running Laravel on the Google App Engine.
Since the App Engine runs PHP using the PHP 5.5 interpreter, I specified php55 as the runtime. The project works well on Google servers.
When I run my site on a local dev server, the SDK provides the use of runtime: php everything works fine. Changing the runtime on php55 gives me a blank page and the following error in my log:
Unable to delete function dlUnable to delete function mb_send_mail ERROR:root:php failure (255) with: stdout: Status: 500 Internal Server Error X-Powered-By: PHP/5.5.23 Content-type: text/html
I installed the latest version of the GAE SDK.
Of course, I can work with the runtime variable set in php instead of php55, but I'm still wondering why runtime: php55 does not work on localhost, and if I missed something here.
