Differences between Traits and Inheritance

Understand the distinctions between traits and inheritance in PHP to effectively share code among classes. Discover how traits enable horizontal inheritance to overcome single inheritance limits, when traits are preferable, and the advantages and caveats of using traits in object-oriented PHP programming.

We'll cover the following...
