Can someone explain ($this->varname) to me..

How and what does this mean in php: ($this->varname)

I can't seem to find this by searching Google, because the "->" are
removed from my search query.

Cheers,

-> is used when referring to a classes inner workings. $this is a
special variable used within a class to refer to itself.

Example:
----------------------------------------
class Example{
var $classVariable = "Something";

function testFunction(){
echo "I'm just a simple function.";
}

function show(){
$this->testFunction();
}
}

$c = new Example;
$c->testFunction(); // Returns I'm just a simple function.
$c->show(); // Returns I'm just a simple function.
echo $c->classVariable; // Returns Something
------------------------------------------

Hope that clears thing up for you.

To be more precise: it refers to the containing object (instance of a
class). A reference to a class itself would normally be something like
self::$varname.

My new ISP's newsserver sucks. Anyone recommend a good one? Paying for
quality is certainly an option.

$this->varname refers to a class variable (property) which is available to
any function (method) within that class. This is not to be confused with
$varame which refers to a variable whose scope is limited to the current
method.

$this->function() refers to another function (method) within the same class,
as opposed to function() without $this->) which refers to a non-class method
which exists in global scope.

Basically $this-> is used within a class method to refer to something else
which exists within the same class.
