 +==== Deprecate the register_argc_argv INI directive ====
 +
 +Author: Nicolas Grekas <nicolas.grekas@php.net>
 +
 +This INI directive tells PHP whether to declare the argv & argc variables. On the CLI, phpdbg and embed SAPIs it is forced to On. It defaults to Off on other SAPIs. This setting is dangerous on HTTP SAPIs because it allows defining the value of the argv/argc variables from the query string. This is almost always unwanted and certainly unexpected. It can lead to security issues if one reads argv/argc from an HTTP apps while not being aware of this behavior.
 +
 +We propose to deprecate this INI setting and make in default to Off in PHP 8.5, then to hardcode it to Off for all non-CLI-related SAPIs on PHP 9 (while keeping it hardcoded to On for CLI-related ones).

 +
 +==== Deprecate semicolon after case in switch statement ====
 +
 +Author: Theodore Brown <theodorejb@php.net>
 +
 +It is possible to terminate ''case'' statements with a semicolon instead of the standard colon:
 +
 +<PHP>
 +switch ($value) {
 +    case 'foo';
 +    case 'bar':
 +    case 'baz';
 +        echo 'foo, bar, or baz';
 +        break;
 +    default;
 +        echo 'Other';
 +}
 +</PHP>
 +
 +This syntax is a leftover from PHP/FI 2, where nearly all lines including if conditions and case statements were terminated by a semicolon. [[https://externals.io/message/109350#109363|1]] [[https://www.php.net/manual/phpfi2.php#lang|2]]
 +
 +There isn't a need for this syntax to exist anymore, and very few PHP developers are even aware of its existence. In the top 1000 Composer packages, zero out of 35,777 total case statements are using the alternate syntax (as of 2024-11-27).
 +
 +Case statements followed by a semicolon can cause confusion, as a developer may think they behave differently in some way from regular case statements (e.g. preventing fallthrough), when they do not.
 +
 +Therefore, we propose to deprecate terminating case statements with a semicolon.
 +
 +
 +==== Deprecate the $exclude_disabled parameter of get_defined_functions() ====
 +
 +Author: Gina Peter Banyard <girgias@php.net>
 +
 +As of PHP 8.0.0, functions that are disabled via the ''disable_functions'' INI setting are simply removed from the function table.
 +As such, this parameter has no longer any effect and is pointless.
 +Therefore, we propose to deprecate it.
