Deprecations for PHP 8.7
The RFC proposes to deprecate the listed functionality in PHP 8.7 and remove it in PHP 9 (except where otherwise noted).
array_search_range()
This RFC proposes a new core function named array_search_range().
Native Immutable Collections — "vec", "set" and "tuple"
PHP's array is a single, mutable type that serves as an ordered list, an
associative map, a record and a set at once. That versatility means an array
type decla...
Strict Namespace Resolution
Inside a namespace, PHP resolves an unqualified function or constant name in the current namespace first, then falls back to the global namespace. Unqualified c...
Direction-Aware Property Resolution
PHP 8.4's asymmetric visibility (private(set) / protected(set)) is enforced by re-checking set access on every write: each assignment to an asymmetric property ...
Extension Methods
This RFC proposes extension methods: the ability to declare additional methods for an existing class or interface from outside its definition, resolved at call ...
Scalar Extension Methods
The Extension Methods RFC lets code declare additional methods for existing classes and interfaces, resolved only where PHP would otherwise raise an undefined-m...
Extension Method Autoloading
The visibility RFC draws a line it inherits from every other use statement: importing is not loading. use extension Vendor\Name; grants visibility, but the decl...
Extension Method Visibility (use extension)
The Extension Methods RFC gives extensions load-gated visibility: once a file declaring extension Target { } has executed, its methods are resolvable from anywh...
Catchable MemoryError for predictably oversized allocations
When a PHP program requests an allocation whose size the engine can compute before doing any work, the request ends in an uncatchable fatal error. Examples incl...
str_mask()
In modern web development, obfuscating or masking sensitive user data (such as credit card numbers, phone numbers, email addresses, and national IDs) is a daily...
#[\Deprecated] for interfaces
The #[\Deprecated] attribute was introduced in PHP 8.4 (deprecated_attribute) and could be used to emit deprecation warnings when calling a function (or class m...
Explicit fallthrough for ''switch''
This RFC proposes to add a fallthrough; marker to switch to prevent accidental fallthrough, helping to avoid bugs while making intentional fallthrough visible a...
URI/URL Path Segment Support
Sometimes, accessing path segments rather than the whole path as string is needed. When this is the case, splitting the path to segments manually after retrieva...
Add ReflectionAttribute::getCurrent()
Attributes were first introduced in attributes_v2 in PHP 8.0, with the current syntax adopted shorter_attribute_syntax_change. Userland attributes provide a way...
#[\NonExhaustive] marker
The elevator pitch for the RFC. The first paragraph of this section will be rendered slightly larger to give it emphasis.
Add str_iter() for UTF-8 code-point iteration
PHP does not currently expose a small shared primitive for iterating over a string as UTF-8 code points. This RFC proposes such a primitive in the form of str_i...
Add FILTER_VALIDATE_STRLEN for UTF-8 code point length validation
This RFC treats code-point length validation as part of PHPs built-in validation baseline rather than as a specialized text-processing feature.
SORT_STRICT Flag
This RFC proposes SORT_STRICT, a new flag that enables deterministic, type-aware sorting without sacrificing PHP's flexibility with mixed-type arrays.
Allow __sleep() to return null or no value to delegate to default serialization
The __sleep() and __wakeup() magic methods have been part of PHPs object serialization model since early versions.
However, they have long served multiple unr...
#[\NotSerializable] attribute
PHP already has a robust engine-level mechanism for forbidding serialization of certain types (e.g., closures, internal classes). This RFC proposes exposing tha...
Function composition operators
In object-oriented code, composition generally means one object having a reference to another. In functional programming, composition generally means sticking ...
Who Can Vote (2024)
The original voting RFC allowed two audiences to vote, but because the original VCS account system has fallen out of use new accounts are not being added there,...
Deprecate FFI non-static methods
FFI::new(), FFI::type(), FFI::cast() support static and non-static access, which is very confusing. This issue has been proposed to be amended in the RFC that h...
Change the default of $characters in mb_trim function
We found a problem with $characters, the second argument of mb_trim. This RFC will be a proposed solution to that problem.
is_json
This RFC introduces a new function called is_json() to validate if an string contains a valid json.
Short Closures
Callables syntactically have few ways of passing them around.
This RFC is supposed to introduce unified short way of creating closures from callables
and reduce...
Property type-hints
With the addition of type-checked function return values in PHP 7, we are one step closer to PHP being a gradually-typed language. This RFC proposes to close th...
Invoke __callStatic when non-static public methods are called statically
The _ _callStatic magic method should be invoked when non-static public methods are called in a static context.
