What does this php construct mean: $html->redirect(“URL”)?

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"

  • would this be the same as saying bar($value)? – Mankind1023 Aug 06 '10 at 14:55
  • No... bar($value) is not really useful without having $object=new foo(); and calling $obj-bar() which is a method, whereas $value is a member/field of the class. – Chris Aug 06 '10 at 23:36
