[php-src] Issue #20274: SoapClient::__doRequest undocumented backwards incompatible in PHP 8.5

Issue: https://github.com/php/php-src/issues/20274 Author: brainfoolong ### Description I found an undocumented backwards incompatible change that is breaking exsint SoapClient implementations?! Here, this break is not listed https://github.com/php/php-src/blob/php-8.5.0RC3/UPGRADING Here, this change is documented but not as breaking https://github.com/php/php-src/blob/ad19b3e570e0760ec55f4357ae69f989345e4d61/NEWS#L341 The signature of SoapClient::__doRequest has changed, so it triggers the following errors in userland code ``` Declaration of xxxt::__doRequest($request, $location, $action, $version, $oneWay = 0): ?string must be compatible with SoapClient::__doRequest(string $request, string $location, string $action, int $version, bool $oneWay = false, ?string $uriParserClass = null): ?string ``` Which i guess is quite common because you almost always have to override this function in SoapClient. Do i miss something? ### PHP Version ```plain PHP 8.5RC3, since PHP 8.5beta1 ``` ### Operating System _No response_
