PHP only supports single inheritance, but with the use of traits, we can achieve multiple inheritance.
A trait in PHP is like a set of reusable functions that you can add to different classes. It's a way to share code between classes without using regular inheritance.
Lets take an example:-
1. Declare Trait
We can declare a trait with the trait keyword:
<?php
trait Trait1 {
public function method1() {
echo "Method 1 from Trait1!";
}
}
trait Trait2 {
public function method2() {
echo "Method 2 from Trait2!";
}
}
?>
Above we have declared two traits.
2. Use of Trait
To use a trait in a class, use the use keyword:
<?php
trait Trait1 {
public function method1() {
echo "Method 1 from Trait1!\n";
}
}
trait Trait2 {
public function method2() {
echo "Method 2 from Trait2!\n";
}
}
class MyClass {
use Trait1, Trait2;
}
$obj = new MyClass();
$obj->method1(); // Output: Method 1 from Trait1!
$obj->method2(); // Output: Method 2 from Trait2!
?>
I hope You understand the concept of traits.
