Edit report at https://bugs.php.net/bug.php?id=81508&edit=1 ID: 81508 Comment by: McCullough1980Alice at gmail dot com Reported by: mintobit at gmail dot com Summary: http_build_query returns empty string given ArrayIterator as input Status: Open Type: Documentation Problem Package: URL related Operating System: Linux PHP Version: 7.4.24 Block user comment: N Private report: N New Comment: 've reimplemented http_build_query to leave empty objects/arrays in the returned query string (suffixed by an '=' symbol). I've enhanced it a bit from the default functionality as well, so all-in-all: Maintains empty objects and arrays Changed the default enc_type to RFC3986 (relevant to the ages) Added a key-value separator argument (ability to override the default '=') Removes numeric indices for numerically-indexed key-value pairs I have not tested this in a production environment (no idea about performance or bugs), and it is not optimized, but very well spelled out.

My brain likes to bundle them together. Presumably it's the same underlying change affecting both. ------------------------------------------------------------------------ [2021-10-05 18:33:36] salathe@php.net > Calling get_object_vars() on an ArrayObject instance will now ... The quoted section from the migration guide references ArrayObject, but makes no mention that the change also applies to ArrayIterator. ------------------------------------------------------------------------ [2021-10-05 16:00:28] requinix@php.net > Calling get_object_vars() on an ArrayObject instance will now always return the > properties of the ArrayObject itself (or a subclass).

The third bullet point is the one that affects http_build_query(). ------------------------------------------------------------------------ [2021-10-05 15:28:03] mintobit at gmail dot com Description: ------------ Have not found anything related here https://www.php.net/manual/en/migration74.incompatible.php. Would appreciate if somebody can explain why this happened: wondering if this is expected and should be documented. Test script: --------------- <?php $array = [ ['ids' => [1,2,3,4]], ['key' => 1] ]; var_dump(http_build_query(new ArrayIterator($array))); Expected result: ---------------- string(92) "0%5Bids%5D%5B0%5D=1&0%5Bids%5D%5B1%5D=2&0%5Bids%5D%5B2%5D=3&0%5Bids%5D%5B3%5D=4&1%5Bkey%5D=1" Actual result: -------------- string(0) "" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81508&edit=1
