Traits in php are the mechanism for reusing the code in a single inheritance.

Trait is as similar as a class, but only focus to group functionality in a consistent way to fine grained. We can not instantiate a Trait . It is for reducing some limitations of single inheritance for reusing group of methods easily in different independent classes in a different class hierarchies.

We can do Multiple Traits insertion into a class by listing all in the use statement, and separated them by commas.Please note that If we insert two Traits having method with the same name, then a fatal error is produced.

Example

class BaseClass{
    function getReturnType() {
        return 'BaseClass';
    }
}
trait traitSample {
    function getReturnType() {
        echo "TraitSample:";
        parent::getReturnType();
    }    
}

class Class1 extends BaseClass {
    use traitSample;   
}

$obj1 = new Class1();
$obj1->getReturnType();//TraitSample:BaseClass
