If you override a method which was defined by a trait, calling the parent method will also call the trait's override. Therefore if you need to derive from a class which has a trait, you can extend the class without losing the trait's functionality:
<?php
trait ExampleTrait
{
public function output()
{
parent::output();
echo "bar<br>";
}
}
class Foo
{
public function output()
{
echo "foo<br>";
}
}
class FooBar extends Foo
{
use ExampleTrait;
}
class FooBarBaz extends FooBar
{
use ExampleTrait;
public function output()
{
parent::output();
echo "baz";
}
}
(new FooBarBaz())->output();
?>
Output:
foo
bar
baz
