In PHP, when you use traits in a class, you may encounter situations where the same method is defined in multiple traits. To avoid method conflicts, PHP provides a mechanism to resolve them using the `insteadof` and `as` keywords. This allows you to deduplicate methods when they are inherited from different traits.
Here’s an example demonstrating how to deduplicate traits:
<?php trait TraitA { public function display() { echo "From TraitA"; } } trait TraitB { public function display() { echo "From TraitB"; } } class MyClass { use TraitA, TraitB { TraitB::display insteadof TraitA; // Use display from TraitB TraitA::display as displayFromA; // Alias display from TraitA } } $obj = new MyClass(); $obj->display(); // Outputs: From TraitB $obj->displayFromA(); // Outputs: From TraitA ?>
