It's been a while since I've studied PHP but I recently started studying Classes (refer to here) and I was wondering what $this is.

And could someone explain the following code to me:

class SimpleClass
{
// member declaration
public $var = 'a default value';

// method declaration
public function displayVar() {
echo $this->var;
}
}
?>

The part that really throws me off is $this->var;


And one more question, what exactly does "Instanciating object" mean?

Hopefully Bigbob or Randy can answer my questions

I havnt done classes in php, but have in java.

This usualy refers to this class.
class SimpleClass
{
// member declaration
public $var = 'a default value';

// method declaration
public function displayVar() {
echo $this->var;
}
}
?>
so the method is saying echo the variable var that is in this class.

Do you understand Example 19.1 ?

EDIT :
Instanciating object i belive is refering to an instance of an object.
$myVar = 3;
Here you have an instance of a variable.

When you use a class, your creating an object, and that object is an instance of that class.
Do you follow?

All that makes perfect sense, your more help than php.net
Thanks


EDIT: Here is an even bigger challenge, what exactly is going on here -


class A
{
function foo()
{
if (isset($this)) {
echo '$this is defined (';
echo get_class($this);
echo ")n";
} else {
echo "$this is not defined.n";
}
}
}

class B
{
function bar()
{
A::foo();
}
}

$a = new A();
$a->foo();
A::foo();
$b = new B();
$b->bar();
B::bar();
?>


and here is an example of that output:
$this is defined (a)
$this is not defined.
$this is defined (b)
$this is not defined.

I seen that example there , heres a breakdown of it.
<?php
class A
{
function foo()
{
if (isset($this)) {
echo '$this is defined (';
echo get_class($this);
echo ")n";
} else {
echo "$this is not defined.n";
}
}
}
Creates a class file, called A, and gives it a function, foo. Foo will echo wether this class is an object or not.

class B
{
function bar()
{
A::foo();
}
}
Creates a class B, with its own function, bar, which calls foo() from class A, but dosnt create an object of it.

$a = new A();
Creates an object of class A, and stores it into $a.
$a->foo();
Uses the object $a and calls the function foo().

A::foo();
Calls the function foo, from class A, but dosnt create an object of it.


$b = new B();
$b->bar();
B::bar();
Same for these ones.
?>


$a = new A(); |=| Creates the object
$a->foo(); |=| Calls the function foo, of object $a ($this is defined (a))
A::foo(); |=| Calls the function foo, without making an object ($this is not defined.)

A little bit of extra stuff that you can probably guess.
get_class($this);
Will return the object name
n new line character.

I'm not sure if this is PHP related but I'm guessing it is. How do you make a url that ends with a / instead of a .html or .php?

Example:
www.test.com/articles/1121

Those numbers 1121 might just be the name of the folder and in that folder if there's any file named 'index' that page will automatically be loaded.

That make sense?

Well the name of the file needs to be index followed by an extension; examples:
index.htm
index.html
index.php
index.aspx
etc...

there is also some order to which what files run first (maybe alpahbetcial extention).

eg.
index.php
index.html
in the same directory, index.html will run instead of index.php. Hopefully my shortend example makes sense.
