"->" When only we use it?

[pplNet]

Hi all,

I am totally confused about this thing "->"....

I know it appear during we call records like

$resource->field

we also use it in class method.

 

But in some cases I saw ppl use it in Array...

So, what is the meaning of "->"???

when we use it?

how we use it?

 

I found this from Joomla code

$arr[$i]->$key;

 

Please explain if anyone know.

 

Thanks for everyone!

That's probably because $arr is an array of objects.

[BlueSkyIS]

that's what i was thinking. then $key is a method for that object.

 

$object->obj_variable_or_function

 

$array_key=>$value
