ookla speed test mini upload calculation failing

My boss wanted me to setup this mini speed test tool to be used by our clients in testing our mobile internet speeds; Download and upload.
Details on how to download and setup the tool here

I managed to setup the tool successfully but i however ran into a small problem.
The download calculation was working fine, but the upload calculation that uses a script called "upload.php" was failing.

The tool would only stop at calculating the download speed, the upload icon would highlight but the calculation simply wouldn't happen.


For my particular case, the problem was that my Apache2 configuration was never set to recognize php scripts and that's why when ever i would run that file in a browser e.g "http://x.x.x.x/mini/speedtest/upload.php" instead of the script returning the value "size=500", it would return the source code, just like a text file.
And whenever i would run the script directly on the server, it would execute successfully.


Edit the Apache configuration file (i.e. "httpd.conf ") to be able to parse PHP files. Add the lines below:

AddType application/x-httpd-php .php
AddType application/x-httpd-phps .phps
AddType application/x-httpd-php3 .php3 .phtml
AddType application/x-httpd-php .html

Restart Apache

e.g. ./httpd -k restart

I tested again by calling the script in the browser and it executed successfully and returned the value "size=500"

I tested my mini speed test server and it was working OK:
