Maybe request_body_populate_globals?Another option for the name: `populate_multipart_form_data()`.I avoided the term "multipart" because the function technically also works for application/x-www-form-urlencoded requests. It's less necessary for the reasons outlined in my previous email, but it would allow for consistent handling of such requests for all HTTP methods. Some people on GitHub voiced that they would prefer an INI setting. Therefore I will create an RFC accordingly.I know this issue comes up enough because it’s confusing to developers that there’s not a `$_PUT`, etc., but I’m not a fan of introducing something new that populates globals. While I’ve never used `application/x-www-form-urlencoded` data for `PUT` requests (because I don’t think it’s a proper content-type for the semantics of `PUT`), I do see how this content-type could be used with `PATCH`, and I also don’t want to rule-out use cases of it for `PUT` or any other HTTP method. In the past, I’ve used something like the following to solve this: parse_str(file_get_contents('php://input'), $data); I haven’t looked up how any of the frameworks solve this, but I would be willing to bet they also do something similar. Rather than implementing functionality to populate globals, would you be interested in introducing some new HTTP request functions. Something like: http_request_body(): string http_parse_query(string $queryString): array `http_request_body()` would return the raw body and would be the equivalent of calling `file_get_contents('php://input')`. Of special note is that it should _always_ return the raw body, even if `$_POST` is populated, for the sake of consistency and reducing confusion. `http_parse_query()` would be the opposite of `http_build_query()` and would return a value instead of requiring a reference parameter, like `parse_str()`. While these don’t address the confusion users face by not having a `$_PUT` superglobal, I’d prefer not to overload the superglobals. Maybe we can update the documentation to encourage use of these new functions instead of the superglobals? We also might want to introduce something like `http_query_string(): string` that always returns the raw query string, instead of requiring use of the superglobal `$_SERVER['QUERY_STRING']`. Cheers, BenAs a userland/library developer I *much* prefer this approach, but *please* also include `http_uploads()` (name/signature TBD), returning an array of file uploads using a structure akin to what $_POST (or http_parse_query) gives, based on the field name, rather than the current scenario where the presence of square brackets radically changes the structure of the $_FILES array. My initial thought was that perhaps the leaf entities in said array could be a subclass of SplFileInfo referencing the uploaded temporary file, with additional read-only properties for the extra upload-related attributes - but really the important thing is just having a sane, consistent structure. Having an object rather than an array with constant keys would be a nice addition, but is much less important. Cheers StephenI also like Ben's suggestion. It avoids adding more magic globals, but also is still simple and straightforward to use in an easily composable fashion. Based on the Content-Type header of the request, it would allow for: $formData = http_parse_query(http_request_body()); $jsonData = json_decode(http_request_body()); ... Whatever other body parsers. While you should probably not call it exactly like that, it means "take body string, pass to mime-appropriate body parser" is an easy pattern, and one that can also be easily mocked for testing.
While I like not adding more Superglobals, it seems like we are adding more and more functions to retrieve the different parts of a Request-Object...
So when we are at it: Why don't we introduce exactly that? A Request-Object that has all the methods. And which is immutable.
And one method `request(): \Request`I deliberately didn't call it `getRequest` (or `get_request`) to not confuse people why there isn't also a `post_request` or `put_request` or ... you get the picture)
One additional function in global namespace and then we can use one of the request-objects that are already out in the wild. I don't think there's a need to invent the wheel again.
The advantage might be that no matter how many calls to `request()` you will always get the same result. The Request as it came in.
Just my 0.02€
