PHP 5 __Get() Method
PHP __get Magic Methods
PHP is a loosely coupled programming language, so that you can use variable without declaring it. It is one of the features of a loosely coupled programming language.
In other programming languages you must need to declare the variable before using it.
Example
<?php
class Computer {
public $processer;
}
$c = new Computer();
$h=$c->processer = "Intel Core I3";
$h1=$c->color = "Black";
echo $h." ".$h1;
?>
Output
Intel Core I3 Black
If you run this code it will run properly even assign a value to undefined variable "color".
__get method
To intercept attempts to read an undefined property of any class, you create a method called _get() within your Class to give the response of undefined property.
(Two underscore in font of get) __get() method should expect a single parameter the name of the requested property. It should then return a value this value in turn gets passed back to the calling code as the retrieved property value.
Example __get method
<?php
class Computer
{
public function __get( $model ) {
echo "The requested $model of the computer
";
return "Sony Vaio E series";
}
}
$Computer = new Computer;
$a = $Computer-> model;
echo "The Computers model is $a
";
?>
Output
The requested model of the computer
The Computers model is Sony Vaio E series
In the above example, the Computer class contains no actual properties, but it does contain a _get() method. If anyone request any undefined property then it prints the requested property and returns Sony Vaio E series .
