Hi, I've been looking for what this operator "->" does, but I can't seem to find a reference to it, only people using it in come and I can't make out what its doing, an explanation would be appreciated.

The -> is used with object methods/properties, example:

class foo{
  function bar(){
    echo 'Hello World';
  }
}

$obj = new foo;
$obj->bar(); // Hello World

It's for classes.

-> operator access properties and methods of an object.

Probably you should read PHP OOP introduction: http://php.net/manual/en/language.oop5.php

Expanding on sarfraz's answer to demonstrate how to access properties:

class foo{
  public $value = "test"; 
  function bar(){
     //// code
  }
}

$obj = new foo;
$obj->bar();
echo $obj->value;     //displays "test"
