Find a file containing a class (based on __autoload), but don't include it

Question

I am using Composer to load PHP dependencies. Given the name of the class I want to find path of the file where this class is defined, but don't include it.

Example:

echo get_file_for_class('Carbon\\Carbon');

Output:

vendor/briannesbitt/Carbon/src/Carbon/Carbon.php

Thanks!

You could use the Reflection Class. http://php.net/manual/en/class.reflectionclass.php

$reflector = new ReflectionClass('Carbon\\Carbon');
echo $reflector->getFileName();

There are some additional useful class methods you could also play around with, to determine its parent, if it inherits from one, or its start line.

$reflector->getParentClass();
