Description:
------------
http_build_query(array()) returns NULL. According to the documentation, the return type of http_build_query is string.

This can be considered a documentation problem, but I think it would be better to change the function so that it always returns a string.

Reproduce code:
---------------
./php.exe -r "echo gettype(http_build_query(array()));"



Expected result:
----------------
string


Actual result:
--------------
NULL
