When you call http_build_query() method with array which contain one object, http_build_query don't call Ā«__toStringĀ» method 

Test script:

class foo {

        public function __toString()
                return "bar";

$params = array();
$params['a'] = 'b';
$params['foo'] = new foo();

$query = http_build_query($params);

var_dump($params, $query);

Expected result:

Actual result:

Is there any progress information available for this bug? It's pretty annoying since it means you always have to roll your own alternative to http_build_query.

I can confirm the behavior: <>. However, I'm
not sure whether this qualifies as bug in PHP (it seems to be more
like a feature request).

Anyhow, you could simply cast the object to string manually, see

After having had a closer look at the implementation and the
documentation of http_build_query(), the behavior is not a bug,
but rather by design. The query string is build from arrays as
well as objects *recursively*. Example #4[1] demonstrates how that
works for nested objects.

Changing the behavior would be too much of a BC break for a small
gain (avoiding the manual cast to string). The documentation could
be improved however, to point out the behavior more clearly.
Therefore I'm changing to "Documentation problem".
