Case-sensitive PHP
PHP has always treated function, method, and class names as case-insensitive. That was a pragmatic early design decision, but it now creates inconsistency witho...
Deprecate Metaphone Function
This RFC proposes the deprecation of the metaphone function in PHP 8.6
Remove \0 from default trim() character mask
The trim(), ltrim(), and rtrim() functions strip whitespace (or other characters) from the beginning and end of a string. When the second parameter ($characters...
Deprecate PEAR and recommend Composer
The RFC proposes to deprecate PEAR, and to recommend Composer for installing PHP packages going forward.
Add "is_representable_as_float()" and "is_representable_as_int()" functions
This RFC proposes the addition of two new functions to PHP's standard library: is_representable_as_float() and
is_representable_as_int().
Minor version compatibility
This RFC aims to clarify and codify the rules regarding backward compatibility and userland API compatibility in PHP minor versions. Currently, there is no form...
Change behaviour of array sort functions to return a copy of the sorted array
The PHP array sort functions take the array to sort as a by-reference array to sort the array in place.
However, since PHP 5.6 these function have only ever ret...
Default expression
The only way to pass the default value to a function or method parameter is to not pass anything. This can be particularly difficult in some circumstances, beca...
Using and Mentioning Third-party Packages in PHP Documentation and Web Projects
The PHP project has had a long-standing but unwritten, vague, and inconsistently applied proscription against mentioning or using third-party PHP projects on th...
Code optimizations
According to https://github.com/php/php-src/blob/master/CONTRIBUTING.md, pull requests are only allowed for three things:
Auto-implement Stringable for string backed enums
The engine currently doesn't allow enums to implement Stringable. This RFC proposes that string-backed enums auto-implement Stringable, while still disallowing ...
Allow null as standalone type
null corresponds to PHP's unit type, i.e. the type which holds a single value.
Never For Parameter Types
Parameters in PHP are contravariant to preserve Liskov substitution. This means that if class B extends class A, then redefines a function call, the entire type...
Unwrap reference after foreach
After a foreach by reference loop, the value variable currently remains a reference to the last array element, which may result in unexpected behavior if the va...
clamp
clamp checks if a int|float value is within a certain bound. If the value is in range it returns the value, if the value is not in range it returns the nearest ...
Add http_parse_query as an alternative to parse_str
PHP offers a function for parsing query string into an array. The function, for historical reasons, has been designed to allow registering the values as global ...
Deprecate ticks
Ticks allow running a function for every N low-level tickable statements. Historically, they have been used for handling pcntl signals. However, they have outli...
debug_backtrace_depth(int $limit=0): int
Inspecting the current stack trace depth is occasionally useful for manually debugging, checking for potential infinite recursion, or for checking if code would...
println(string $data = ''): int
Printing a string followed by a newline to stdout is a commonly performed operation in many applications. Many programming languages provide a helper function t...
Wall-Clock Time Based Execution Timeout
On most platforms, PHP currently measures the request timeout based on CPU time, rather than wall-clock time, so neither sleep(), nor network or system calls co...
Strict operators directive
The rules PHP uses for type juggling with operators are complex, varying by operator as well as the types and values of the operands.
Language Constructs Syntax Changes
In 25yrs history, many language constructs were allowed in different forms depending on the context.

instanceof improvements
As currently implemented, the instanceof operator is inconsistent.
Switch expression
The switch statement has some long-standing issues that we're going to look at in this RFC.
Increment/Decrement Fixes
Intuitively, the ++ and -- operators are equivalent to add 1 to variable and subtract 1 from variable, respectively. As such, it would be expected that $a=$a+1,...
Allow function calls in constant expressions
Currently, constant expressions in declarations allow a limited set of expression types such as literals, constants, and operations.
This RFC proposes allowing ...
Switch Expression & Switch Statement Improvement
The current design of PHP's switch statement follows closely languages such as C/C++ and supports fall-through semantics by default.
The traditional switch stat...
Implement strrstr counterpart to strstr for consistency
Implement strrstr (and possibly strristr) for consistency with the strpos string functions family.
Consistent Callables
In PHP most types are consistent; a float is a float whether it is in a function, in a static method, or is a global variable. Ints, bools, resource, strings et...
Locked Classes
Object properties in PHP are primarily defined in class definitions; however, they can also be added to or removed from individual instances at any time. This R...
Kill proprietary CSV escaping mechanism
For many years, we receive bug reports regarding the strange behavior of the $escape parameter of our CSV writing and reading functions (fputcsv, fgetcsv etc.);...
Deprecate and remove continue targeting switch
In PHP, if continue is applied to a switch statement, it behaves the same as break. In other languages, it would continue the surrounding loop instead. To avoid...
Deprecate class instance deserialization in WDDX
WDDX has been designed as programming language independent data exchange format for the web1). However, PHP 4.0.0 added the ability to (de)serialize class insta...
Raise warnings for json_encode() and json_decode() issues
Whenever json_encode() or json_decode() are called, you must call json_last_error() to check if a failure occurred.
Namespaces in Core
Introduce namespaces to user-level symbols to avoid collisions with user defined symbols, decrease breaking changes due to the introduction of new symbols and t...
PDO Float Type
The PDO extension does not have a type to represent floating point values.
Arrow Functions
Anonymous functions and closures can be verbose even though sometimes they are quite simple and contain only a single expression. Additionally, importing variab...
array_change_keys()
This RFC proposes a new core function to simplify the process of changing an array's keys (re-keying).
IntlCharsetDetector
PHP's implementation of ICU is still incomplete. One of the features currently missing is a wrapping of UCharsetDetector meant to make an educated guess as to ...
Revisit trailing commas in function arguments
Arrays in PHP have long since supported trailing commas.
Function Autoloading
PHP presently offers the ability to import class-like structures (classes, interfaces and traits) via a callback (or series of them) that can be registered. Thi...
JsonSerializable New Interface method Proposal
JSON in php currently supports the Serialization of objects using the \JsonSerializable interface. However it does not support the unserialization of JSON strin...
