class A extends B

Prints “abcdef”
Also, from php 5.4 onwards you can use trait
trait business{
function sell(){
}
function buy(){
}
function collectMoney(){
}
}
trait human{
function think(){
}
function speak(){
}
}
class BusinessPerson{
use business;
use human;
// If you have more traits bring more
}
class BusinessWoman extends BusinessPerson{
function getPregnant(){
}
}
$bw = new BusinessWoman();
$bw ->speak();
$bw->getPregnant();
