GTFS Realtime PHP

composer require lowa/gtfs-realtime-php

to install the package and all dependencies. This command will load all packages and update your autoloader to use the package.

Include [MainDirectory]/vendor/autoload.php in the head section of your application code to use all required classes in simple way.

Explaination

This is a simple wrapper for GTFS-Realtime in PHP modified to be compatible with Google library. The gtfs-realtime.proto was edited to match with proto3 definitions.

• Step 1: Remove all 'optional' labels since all fields are optional
• Step 2: Remove all 'required' labels since all fields are optional
• Step 3: Remove all 'extensions' ranges, see https://developers.google.com/protocol-buffers/docs/proto3#any
• Step 4: Remove all explicit default values, see https://developers.google.com/protocol-buffers/docs/proto3#default
• Step 5: Set first value in all enums to PROTO3_DEFAULT_[VARNAME] = 0 to supply implicit default value, see https://developers.google.com/protocol-buffers/docs/proto3#default

Then, using protobuf you can generate all the files of this repo.
