-==== (binary) cast and b"" literals ==== 
- 
-The binary cast and binary string literals were originally introduced as forward-compatibility features for PHP 6. Currently they behave identically to ordinary (string) casts and ordinary string literals. Given that PHP 6 has been dead for years and it is unlikely that it will be resurrected in the same form, it is time to remove these forward-compatibility tokens. 
- 
-Proposed action: Throw a compile-time deprecation whenever binary casts or binary string literals are used.

 Proposed action: Throw deprecation notice if error handler has five or more arguments. Otherwise, do not pass the ''$errcontext''. This prevents circumvention with ''func_get_args()''. Proposed action: Throw deprecation notice if error handler has five or more arguments. Otherwise, do not pass the ''$errcontext''.

 The motivations for removing this functionality are similar to those of ''$php_errormsg'', so it would seem reasonable to deprecate them at the same time. However, unlike ''$php_errormsg'' there exist no //simple// alternatives to ''$http_response_header''. The [[http://php.net/get_headers|get_headers]] function returns only the headers, but not the response body. Getting both requires, to my knowledge, a combination of ''fopen()'', ''stream_get_contents()'' and reading the ''wrapper_data'' from ''stream_get_meta_data()''. The motivations for removing this functionality are similar to those of ''$php_errormsg'', so it would seem reasonable to deprecate them at the same time.
