Migrating from PHP 5.5.x to PHP 5.6.x

Plese notice that default POST data parsing has changed.
php 5.5 with "foo=bar&baz" received
  "foo" => "bar"
and php 5.6 with same input receives:
  "foo" => "bar",
  "baz" => ""

Tested via curl --data 'foo=bar&baz' http://localhost

It can create a problem when earlier json came without correct content-type header.
e.g. {"foo":"bar"} in php 5.5 $_POST was
and in php 5.6 will be
  "{\"foo\":\"\bar\"}" => ""

Tested via curl --data '{"foo":"bar"}' http://localhost
