Special caracters in if statement

[common]

Hi all

 

I have the line of code which forms part of creating zip files,  but I just want to know what some of the characters mean:

  1.) ->

  2.) ::

 

can some one help me pls!

 

if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true)

 

Thanks

Ooh, welcome to Object Orientated Programming, I'd suggest this tutorial (http://www.killerphp.com/tutorials/object-oriented-php/) It will explain everything you need to know about the scope resolution operators ( -> ) and ( :: )

[rwwd]

-> is pointing to the class instance name and :: is virtually the same thing, though the link provided will more than likely answer your question.  As getputdelete says, welcome to OOP, once you get your head around it, it's quite interesting.

 

Have fun!

 

Cheers,
