Answer 1

First test a hello world type php script to testyour basic installation.

Then verify the web server / php engine is running as a user which is in a group allowed to access the applicable /dev/ttyWHATEVER device file corresponding to the serial port. It would be surprising if that were true by default - you'll probably have to add it to the 'dialout' or similar group.

Add some fault checking / reporting to your code.
