what does "->" means?

[kenchix1]

I see some codes with "->" symbol, what does it mean?

something like :

$variable->blahblah

or

$variable=$variable->functionname($variable)

im confused.

It's for object oriented programming.

Meaning that
$variable=$object->functionname($variable)

The variable is set to the return value of functionname in the object.

do a google search for "php oop tutorial" and you should find some info on object oriented programming in PHP :)
