| + | Each feature proposed for deprecation is voted separately. Each vote requires a 2/3 majority, independently of whether it is a language or standard library change. All votes refer to deprecation in PHP 7.2 and removal in the next major version (presumably PHP 8.0). | ||

| - | 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. | + | * No |

| Proposed action: As ''each'' is typically called within loops, throwing a deprecation warning for every call is likely not advisable.

| ===== Backward Incompatible Changes ===== | ===== Backward Incompatible Changes ===== | ||
| Line 161: | Line 212: | ||
| 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.
