php classes

[justsomeguy]

A class with a method with a name same than it's parent class does execute the method immediatly

That's right, that's called a constructor. You can also have a destructor that gets executed when the instance gets deleted. But that syntax is with PHP 4 style classes. For PHP 5 style (which allow destructors), it looks like this:

<?phpclass MyDestructableClass {   function __construct() {       print "In constructor\n";       $this->name = "MyDestructableClass";   }   function __destruct() {       print "Destroying " . $this->name . "\n";   }}$obj = new MyDestructableClass();?>

To call a function you dont put new functionname() in front of it, if you do please correct me.

That's correct, but he was creating instances of his class, not creating or calling functions. However, he did mess up because he didn't name his constructor WWWLanguage, he only named it Language, so it's not a constructor and won't get executed on instantiation. You would have to explicitly call $var->Language() to use it.

BTW, what's the difference between public and private variables?

public variables can be directly accessed from outside of a class instance. Private variables can only be accessed by the class instance itself.

<?phpclass MyClass{   public $public = 'Public';   protected $protected = 'Protected';   private $private = 'Private';   function printHello()   {       echo $this->public;       echo $this->protected;       echo $this->private;   }}$obj = new MyClass();echo $obj->public; // Worksecho $obj->protected; // Fatal Errorecho $obj->private; // Fatal Error$obj->printHello(); // Shows Public, Protected and Private?>

Oh? Why my @&£$*! book didn't tell me about destructors then?Well, thanks.

target tag is deprecated in Xhtml strict, but I use it, simply choose transitional if you choose to use it, I always go transitional, because theres no other way to open new windows except with javascript, and too much trouble, just a note.

So it is after all? I was so used of using XHTML Strict

Only PHP 5 has destructors, PHP 4 does not.
