How to use traits in PHP
What is Traits?
Traits are a mechanism for code reuse in single inheritance languages such as PHP. A Trait is supposed to reduce some boundaries of single inheritance by enabling a developer to reuse units of techniques freely in several impartial training dwelling in unique type hierarchies. The semantics of the mixture of Traits and classes is described in a way that reduces complexity and avoids the typical issues related to a couple of inheritance and Mixins.

echo 'World is Wide';
}
}
class MyHelloWorld extends MainClass {
use FirstTraits;
}
$o = new MyHelloWorld();
$o->sayHelloTeam();
Benefits of Using Traits
1. Reduces code duplication.
2. Prevents complicated types of inheritance that may additionally non-sensible inside the consumer software context.
3. Creation of simple, clear and concise traits to combine with functionality the place required.
Drawbacks of Using Traits
1. Use of traits numerous from the single accountability principle, which is indispensable for some software built.
2. Due to common sense duplication or source code and method conflicts, PHP traits are now not capable to comply with all the strategies of a class.
Difference between Traits and Interfaces in PHP
The main difference between the Traits and Interfaces in PHP is that the Traits define the authentic implementation of each technique within every class, so many classes implement the equal interface but having exclusive behavior, while characteristics are simply chunks of code injected in a category in PHP.
