PHP Traits

This lesson is part of PHP · All levels

Summary

Trait is a set of methods that can be inserted into several different classes with the use keyword, thus overcoming the limitations of single inheritance in PHP. Traits like a piece of code shared that copies its method to the user class. If there is a conflict of method names, the class can choose which one to use with the keyword insteadof.

Key points

Trait allows sharing methods to multiple classes without inheritance.
The keyword use in the class is used to include the trait.
Traits cannot be instantiated with new and not referred to as parent.
The method of collision is solved by insteadof and renaming using as.
