PHP - Interfaces and Traits

Find the error in this code snippet:

trait A { public function run() { return 'A'; } } trait B { public function run() { return 'B'; } } class C { use A, B { B::run insteadof A; A::run as runA; } public function run() { return 'C'; } }

ANo error, code is valid.

BCannot alias trait method when class has same method name.

CConflict resolution must use 'override' keyword.

DClass method run() conflicts with trait methods.

Step-by-Step Solution

Solution:

Step 1: Analyze trait conflict resolution and aliasing
The class resolves conflict by using B::run instead of A::run and aliases A::run as runA.
Step 2: Check class method with same name
The class defines its own run() method, which overrides trait methods as expected.
Final Answer:
No error, code is valid. -> Option A
Quick Check:
Class method overrides traits; aliasing allowed [OK]

Quick Trick: Class methods override traits; aliasing trait methods is allowed [OK]

Common Mistakes:

Thinking aliasing conflicts with class methods
Expecting 'override' keyword for conflict resolution
Assuming error due to method name duplication
