Starting Google App Engine Web Server - php

Question

I'm going through the helloworld tutorial for Google App Engine using PHP (https://developers.google.com/appengine/docs/php/gettingstarted/helloworld). After getting the application set up and ready to go the tutorial tells me to start the web server included with the Google App Engine SDK using the command: google_appengine/dev_appserver.py --php_executable_path= helloworld/. How exactly do I start the web server and where do I put that command in?

Answer 1

After you install the SDK on your machine you'll have a google_appengine directory. I run Windows so mine is located at:
C:\Program Files (x86)\Google\google_appengine
Inside that directory is a python script called "dev_appserver.py" which is what the tutorial wants you to run. Your local machine should also have PHP installed and the script is looking for the location to that since it would be something you'd install yourself.
You'll execute this script from whatever local command line application your OS has (shell for Linux, terminal in Mac, Command Prompt or Powershell in Windows).
I execute mine from the folder one level above my GAE application is stored. To ensure you can properly execute this command, run it with no parameters and you should see this:
python "C:\Program Files (x86)\Google\google_appengine\dev_appserver.py"

dev_appserver.py: error: too few arguments
My command to get this working properly was:
python "C:\Program Files (x86)\Google\google_appengine\dev_appserver.py" --port 8082 --admin_port 8083 --php_executable_path "C:\Program Files (x86)\NuSphere\PhpED\php54\php-cgi.exe" helloworld\
I got this output in Powershell and was able to hit the local url and see "Hellow, World!"

The Google cloud SDK comes with a Launcher in which you could add project files and examine the logs in the GUI. I used python code here but it should behave the same with php.
Go to Google App Engine Launcher -> Select File -> Add Existing Application -> Browse and select the root directory of your PHP/Python/Java/Go application -> Add -> Click Run button -> Click Logs
