what does "->" mean

[krusmal]

Hi,

 

I am new to PHP and am trying my hands on Object Oriented PHP. I need a little help on the symbol ->

 

I know how to use -> symbol. But I have seen some typical examples of it which I dont understand. Please check the following example and somebody tell me what actually it all means and what class structure it is used for:

 

Example::instance()->foo()->bar()->get()->something();

 

 

Please tell me the meaning of the multiple -> symbols in a single statement. I hope it is not a silly question.

Example::instance()->foo()->bar()->get()->something();

 

well, to put it simply it is "short" for this:

 

$example = Example::instance();
$foo = $example->foo();
$bar = $foo->bar();
$get = $bar->get();
$something = $get->something();
