Answer 1

Try ReflectionClass::getFileName - Gets the filename of the file in which the class has been defined. http://www.php.net/manual/en/reflectionclass.getfilename.php

Example:

$reflector = new ReflectionClass("\Geocoder\HttpAdapter\HttpAdapterInterface");
echo $reflector->getFileName();

Or you may use this:

$loader = require './vendor/autoload.php';
echo $loader->findFile("\Geocoder\HttpAdapter\HttpAdapterInterface");

The first method try to load class and return loaded class path. The second method return path from composer database without class autoload.
