Scheduled for release on November 20, 2025, PHP 8.5 is poised to significantly improve the development experience. Rather than dramatic shifts, this update prioritizes practical enhancements aimed at simplifying daily tasks, improving syntax clarity, and providing smarter debugging tools. PHP 8.5 continues PHP’s trajectory of steady, developer-focused improvements.
Major New Features in PHP 8.5
1. Pipe Operator (|>)
The pipe operator introduces function chaining with a left-to-right syntax inspired by functional programming languages, making code more readable and maintainable:
$result = 'Hello World' |> strtoupper(...) |> str_shuffle(...) |> trim(...);
2. New Array Functions: array_first() and array_last()
These simple but powerful functions enable quick access to array elements, simplifying common array operations:
$users = ['Alice', 'Bob', 'Charlie']; $firstUser = array_first($users); // 'Alice' $lastUser = array_last($users); // 'Charlie'
3. CLI INI Diff Tool
A valuable debugging tool, the new command clearly shows differences between current INI settings and the default values, facilitating easier debugging:
php --ini=diff
4. Final Property Promotion
Allows marking properties as final directly in constructors, streamlining code for immutable properties and clearly signaling immutability intent:
class User {
public function __construct(final public readonly string $name) {}
}
5. Attributes on Constants
PHP attributes can now decorate constants, allowing additional metadata and improved maintainability, such as deprecation notices:
#[\Deprecated] const OLD_CONSTANT = 42;
6. #[\NoDiscard] Attribute
Functions and methods marked with #[\NoDiscard] emit a warning when their return values are ignored, helping prevent subtle errors:
#[\NoDiscard("Check the return value for processing errors")]
function bulk_process(array $items): array { ... }
Additional Enhancements
- Persistent cURL handles, improving HTTP request performance.
- New introspection functions for PHP build dates and error handlers.
- Enhanced stack trace clarity.
- Locale direction check support (
locale_is_right_to_left).
Lifecycle and Support Timeline
- Active Support: Until December 31, 2027.
- Security Support: Until December 31, 2029.
