Simple class using php

hello I'm new to PHP and I need help to understand the basics of PHP class.

I want to have example of a class that uses private public protected and static.

and how do they work..

Thanks in advance.

Oh I forgot how to extends also. I'm talking about the parent 开发者_StackOverflowand child something or what.. Thanks again.

Definitely agree with everyone else. You should read up on the 550 million online PHP manuals including the links provided in other answers. In the meantime, you get this:

class one {
   private $name;
   const ONE = 'ONE';

   // php magic function.  allocate memory for object upon instantiation
   // called with new
   public function __construct($name = null) {
      $this->init($name);
   }

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

   // php magic function called when object variable is accessed in a string context
   public function __toString() {
      return __CLASS__ . ': ' . $this->name;
   }

   // static functions can be called without instantiation
   public static function con() {
      echo self::ONE;
   }

   private function init($name) {
      $this->name = $name;
   }
}


// two cannot overwrite method init() -- it is private.
// two has no access to $name.  It is private in one and not visible to two
class two extends one {
   // protected methods can be overwritten
   protected function name() {
      return parent::name();
   }
   // so can public methods
   public function __toString() {
      return __CLASS__ . ': ' . $this->name();
   }
}

// static method call; no instantiation needed
echo one::con() . "\n"; // ONE
// public methods can be called by child class
echo two::con() . "\n"; // ONE
$one = new one('uno');
echo "$one\n"; // one: uno
$two = new two('dos');
echo "$two\n"; // two: dos
$one->name(); // bork! No public access to this method
