PHP is kind of convenient to build web pages that have common header and footer. This is the technique we normally use when coming to building corporate web sites to maintain same look and feel over the entire websites. For example in the following piece of code (index.php), it shows you how it’s used.
The index.php
<?php
$page = $_REQUEST['p'].”.inc.php”;
include “header.inc.php”;
include $page;
include “footer.inc.php”;
?>
<?php
$page = $_REQUEST['p'].”.inc.php”;
include “header.inc.php”;
include $page;
include “footer.inc.php”;
?>

Juiry Zaytsev, someone who has used Prototype for almost a year for building dynamic web apps, has experienced many stupid questions raised on the Prototype discussion IRC channel. According to Juiry, that Prototype is only used at about 15% by most developers.

In a full-fledged Object Oriented Programming language such as Java, method overloading is the technique that you could use to create few functions or methods that having the same names but taking different arguments or parameters. Such as follows, the method findUser(), findUser(String), findUser(String, String) in Java.
public class Users
{
public Collection findUser()
{
// the findUser() is a method that returns
// all users in a java.util.Collection object
}
{
public Collection findUser()
{
// the findUser() is a method that returns
// all users in a java.util.Collection object
}
public Collection findUser(String name)
{
// the findUser(String) is a method that returns the users matched
// by the specified name,
// result returned in a java.util.Collection object
}
public Collection findUser(String firstMame, String lastName)
{
// the findUser(String,String) is a method that
// returns the users matched by the specified
// first and last name, results returned in a java.util.Collection object
}
}
