*
* Define an algorithm skeleton in an operation, and delay some steps into subclasses so that subclasses can define certain steps of the algorithm without altering the structure of an algorithm
*
*/
Abstract class Templatebase
{
Public Function Method1 ()
{
echo "Abstract method1<br/>";
}

Public Function Method2 ()
{
echo "Abstract method2<br/>";
}

Public Function Method3 ()
{
echo "Abstract method3<br/>";
}

Public Function dosomething ()
{
$this->method1 ();
$this->method2 ();
$this->method3 ();
}
}

{
echo "TemplateObject1 method3<br/>";
}
}

Class TemplateObject2 extends Templatebase
{
