/**
* What is proxy mode? I am very busy, busy no time to talk to you, then you want to find me, first find my agent,
* The agent always has to know what the agent can do to do something, that is, two people have the same interface,
* Although the agent can not work, but the agent of the people to work ah.
*/
For example, Simon Qing find pan Jinlian, that pan Jinlian embarrassed reply ah, how to, find that the king of the agent, performance in the program when this:
Define a type of woman first:
/**
* Define a type of woman, Wang and pan Jinlian all belong to this type of woman
*/
Interface kindwomen{
What can a woman of this type do?
Public function Makeeyeswithman (); Throw a wink.
Public function Happywithman (); Happy what? You know that!
}
/**
* Define a pan Jinlian is what kind of person
*/
Class Panjinlian implements Kindwomen {
Public Function Makeeyeswithman () {
Echo ("Pan Jinlian-wink");
}
Public Function Happywithman () {
Echo ("Pan Jinlian is doing that with a man ...");
}
}
and set an ugly king:
/**
* The man is old and clever, she is too old, a man can not see,
* But she has wisdom and experience, she acts as a kind of woman's agent!
*/
Class Wangpo implements Kindwomen {
Private $kindWomen;
/**
* She can be the agent of any woman in Kindwomen, as long as you are of this type
* By default, it is the agent of Pan Jinlian
* @param null| Kindwomen $kindWomen
*/
Public function __construct ($kindWomen = null) {
if (Is_object ($kindWomen) | | $kindWomen instanceof kindwomen) {
$this->kindwomen = $kindWomen;
}else{
$this->kindwomen = new Panjinlian ();
}
}
Public Function Makeeyeswithman () {
$this->kindwomen->makeeyeswithman (); Wang is such a big age, who watch her wink?!
}
Public Function Happywithman () {
$this->kindwomen->happywithman (); I am old, can not do, let the young replace
}
}
Two heroine are on the pitch, the hero should appear:
/**
* Define a Simon Qing, the Hungry Ghost in the man's color
*/
Class Ximenqing {
/**
* This is written in the margin of the river: Simon Qing was pan Jinlian with a bamboo stick knocked a bit is it, obsessed with,
When the king saw it, she began to set up two good deeds, and she was the agent of Pan Jinlian.
* After a lot of facilitation payments, let's assume that:
If there is no king in the middle of the strings, these two shameless can become? It's hard to say!
*/
Public Function __construct () {
Call the King.
$wangPo = new Wangpo ();
Then Simon Qing said, I want to and Pan Jinlian happy, and then the king will arrange the Simon Qing lost chopsticks that play:
$wangPo->makeeyeswithman (); See no, although on the surface when Wang is doing, actually cool is pan Jinlian
echo "<br><br><br><br>";
$wangPo->happywithman ();
echo "<br><br><br><br>";
Adaptation of History, chia by Simon Qing hook away:
$jiaShi = new Jiashi ();
$wangPo = new Wangpo ($jiaShi); Let her be the agent of Chia.
$wangPo->makeeyeswithman ();
echo "<br><br><br><br>";
$wangPo->happywithman ();
echo "<br><br><br><br>";
}
}
/*
* That is a living example, through the agent to achieve a certain purpose, if really remove the link between Wang, is directly west
* Menqing and Pan Jinlian, estimated that it is difficult to achieve Wu song kill sister-in-the-death incident.
* Then we'll think about it, is there any type of woman in the margin? Yes, Lu Junyi's wife Chia (with the solid housekeeper fornication
The name: "If", then we also let the King do her proxy:
*/
Sketch out the Jia:
Class Jiashi implements Kindwomen {
Public Function Makeeyeswithman () {
Echo ("Chia-wink");
}
Public Function Happywithman () {
Echo ("Chia is happy ...");
}
}
Ximen Qing Zhangjia: see above class ximenqing
New Ximenqing ();
The results of the operation are as follows:
Pan Jinlian Wink
Pan Jinlian is doing that with a man.
Chia Wink
Chia is happy ...
