In a class what does var do?

[dave_merwin]

In the following sample what does var do?

class someclass {

var $something;

} 

Does it instantiate the variable?

Wouldn't you just say the following to make it exist?

class someclass {

$something;

} 

I am really confused.

You declare variables that way. By doing that outside you make the variable accessible from any method inside the class:

class Something {

var $something;

function Something($something)
{

$this->something = $something;

}

function somethingElse()
{

//look i can access that variable from here
return $this->something;
}

} 

Silly

I'm sorry, but I just got the anthology (PHP ANTHOLOGY). I do not understand your example. To save you all the hard work... is this correct?

Class = stores many functions and methods
Function = does one thing
Method = the way that thing is done

My comments are in your code.

class Something {

var $something; //Make teh variable accesable?

function Something($something)
{

$this->something = $something; //This version of teh var something is something?

}

function somethingElse() //new function
{

//look i can access that variable from here
return $this->something; //stop the script and get $something?
}

} 

Is that right?
