Description: ------------ http_build_url function documentation states "The parts of the second URL will be merged into the first according to the flags argument." however, if you use the test code present in "the reproduce code" section and place it in a directory called "foo" Reproduce code: --------------- <?php var_dump(http_build_url("http://foo.com", array('path'=> 'foobar.txt'))); ?> Expected result: ---------------- I expect the function to return string(25) "http://foo.com/foobar.txt" or the documentation changed stating that the current path is going to be appended to $url (????) Actual result: -------------- however it returns string(29) "http://foo.com/foo/foobar.txt"

Sorry, actually documentation is out of date. The default value of "flags" is HTTP_URL_REPLACE|HTTP_URL_FROM_ENV which means, if there's no corresponding URL part in the first URL (in your example there's no path) it's taken from the environment. Use HTTP_URL_REPLACE as flags parameter to http_build_url and you should get your expected result.
