It is a concept of accessing the features of one class from another class. If we inherit the class features into another class, we can access both class properties. We can extends the features of a class by using 'extends' keyword.
<?php
class a
{
function fun1()
{
echo "rookienerd";
}
}
class b extends a
{
function fun2()
{
echo "SSSIT";
}
}
$obj= new b();
$obj->fun1();
?>Output:
<?php
class demo
{
public function display()
{
echo "example of inheritance ";
}
}
class demo1 extends demo
{
public function view()
{
echo "in php";
}
}
$obj= new demo1();
$obj->display();
$obj->view();
?>Output:
