__set() & __get() Magic Methods

In the below example class Foo uses set and get methods while class Bar uses the magic methods. To summarise set and get, basically if you are trying to access a property of an object (and it has a get method) the name of the property you are requesting is passed into the get method and it can handle it how it wants. set works the same but it is only called when you attempt to assign a value to a member variable. The only difference being set takes two paramemters, the variable its setting and the value. 




class Foo{

    private $name;
    private $age;

    public function setName($name){
        $this->name = $name;
    }

    public function getName(){
        return $this->name;
    }

    public function setAge($age){
        $this->age = $age;
    }

    public function getAge(){
        return $this->age;
    }

}

$foo = new Foo();
$foo->setName("Dougal");
$foo->setAge(10);

echo $foo->getName(). " is " . $foo->getAge(). " years old\n";

class Bar{

    private $name;
    private $age;

    public function __set($var, $val){
        $this->$var = $val;
    }

    public function __get($var){
        return $this->$var;
    }

}
$bar = new Bar();
$bar->name = "Dougal";
$bar->age = 10;

echo $bar->name . " is " . $bar->age. " years old";
?>

what is interface in php? how it is use?

An Interface is like a template similar to abstract class with a difference where it uses only abstract methods. In simple words, an interface is like a class using interface keyword and contains only function declarations(function with no body). An Interface should be implemented in the class and all the methods or functions should be overwridden in this class. for eg: interface InterfaceName{ function fun1(); function fun2(a,b); } class ClassName implements InterfaceName{ fuction fun1(){ function implementation....... } fuction fun2(a,b){ function implementation....... } }

PHP Redirect

1. 
      header( 'Location: http://www.yoursite.com/new_page.html' ) ;
   
   ?>

   Change the code on the redirect page to be simply this. You need to replace the URL above with the URL you wish to direct to.
2. Be sure that you do not have any text sent to the browser before this, or it will not work. Your safest bet is to simply remove all content from the page but the redirect code.
   

   
   
   
      //this will NOT work, the browser received the HTML tag before the script
   
   
      header( 'Location: http://www.yoursite.com/new_page.html' ) ;
   
   ?>
