Description:
------------
C standard is to use -I to add an include path for header files. There are also the environment variables CPATH, C_INCLUDE_PATH and CPLUS_INCLUDE_PATH.

Other languages follow suit. Python uses the PYTHONPATH environment variable. Perl uses PERL5LIB *and* -I, and also has a runtime 'use lib' too.

PHP's current only way of doing it is to set the config itself (I didn't see anything about environment variables in the docs on include_path), which usually involves getting the config and manually merging the extras. 

Setting include paths is a much more common operation than the procedure to do so would suggest; it would be very helpful for this boilerplate code (get, merge, set) to be performed by PHP itself as a result of an option. -I is a good idea because it's established by C already, and hence maintains consistency. It would also be useful to honour an environment variable and possibly also a runtime function, just to make it easier.

While I agree somewhat with your sentiment

You can use php --define include_path=/path/to/your/stuff or shorter, -d include_path=/path/to...

You could also do this entirely in PHP, by reading the environment and using set_include_path().

You can also use environment variables in the INI files[1].
