I encountered a problem after upgrading from 5.1.4 to 5.4.0 on PHP 7.4. I am unable to retrieve PUT data, which is always empty, but reverting back to version 5.1.4 resolves the issue. Currently, the project is using the ContentType application/x-www-form-urlencoded.

var_dump($_SERVER['HTTP_CONTENT_TYPE']);
var_dump($this->request->getPut());
exit;

The Result:

string(33) "application/x-www-form-urlencoded"
array(0) {
}

I looked into the code for both 5.1.4 and 5.4.0 and found the issue seems to be with the getPatchPut() function.

getPatchPut in 5.4.0:

I'm not sure if version 5.4.0 no longer supports application/x-www-form-urlencoded, or is there a way to make PUT work under x-www-form-urlencoded?

This has been resolved in #16520
