PHP 8.5 vs 8.4: The Five Features That Change How You Write Code

Short summary

PHP 8.5 introduces five features that improve code readability and maintainability: the pipe operator (|>) for left-to-right data flow, clone with property overrides for immutable objects, #[\NoDiscard] attribute for important return values, standards-compliant URI parsing, and first-class closures in constant expressions. Each replaces common 8.4 workarounds, reducing boilerplate and improving code safety.

• •Pipe operator (|>) enables left-to-right method chaining instead of nested calls
• •Clone with property override simplifies immutable object withers without readonly assignment issues
• •First-class closures, URI extension, and #[\NoDiscard] attribute improve expressiveness and catch bugs earlier
