In PHP, a trait is a way to enable developers to reuse methods of independent classes that exist in different inheritance hierarchies.
Simply put, traits allow you to create desirable methods in a class setting, using the trait keyword. You can then inherit this class through the use keyword
Example:
trait hello {
public function message1() {
echo "Nature is precious,
";
}
}
trait world{
public function message2() {
echo "So Let us unite to preserve it";
}
}
class InUnity {
use hello;
}
class WeCan {
use hello, world;
}
$obj = new InUnity();
$obj->message1();
echo "****************
";
$obj2 = new WeCan();
$obj2->message1();
$obj2->message2();
