 +
 +==== 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.
 +
 +==== Deprecate building ext/ldap against Oracle LDAP ====
 +
 +Author: Christoph M. Becker <cmb@php.net>
 +
 +Building ext/ldap against Oracle LDAP had been supported, and is theoretically still supported, but is apparently [[https://github.com/php/php-src/issues/15051|broken for a while]].  The Oracle LDAP implementation is part of Oracle Instant Client, and uses an older LDAP API; apparently, there are no plans for updating this.  So users are almost certainly better off to build against OpenLDAP (and if they need OCI8, to build that as shared library, and load after ext/ldap).
 +
 +Therefore we supposed to deprecate building ext/ldap against Oracle LDAP.
 +
 +It should be noted that the ``ldap_connect_wallet()`` function, [[https://wiki.php.net/rfc/deprecate_functions_with_overloaded_signatures#ldap_connect|available only as of PHP 8.3]], would also be part of the deprecation, as well as other existing Oracle LDAP specific features.
 +
 +==== Deprecate passing null to readdir(), rewinddir(), and closedir()  ====
 +
 +Author: Gina Peter Banyard <girgias@php.net>
 +
 +TODO: This assumes the last open directory stream opened with <php>opendir()</php> or <php>dir()</php>
 +we have deprecated such usages previous (see mysql and pgsql).
 +
 +
 +==== Deprecate the $context parameter for finfo_buffer()  ====
 +
 +Author: Gina Peter Banyard <girgias@php.net>
 +
 +This parameter is unused, and the only reason it exists in the first place is because the implementation of it was delegated to a "god" C function that also was handingl <php>finfo_file()</php> which does use the provided context.
 +
 +As this parameter is not useful for this function it should be deprecated.
