Nice code keep up the good work

 

What does this restock alerter do?

Forgive me, I'mnot a programmer so I can't just read the code and figure it out. But the title makes it sound very interesting.

 

Seems like it just refreshes the page continuously and checks against a list to see if the shop has restocked, when it does it will alert you and ask you to reload the page in order for it to check again. Basically if you are a "legit" player this might come in handy since you don't have to refresh the page continuously, instead it alerts you when the shop does restock.

 

Well I hate to sounds like I'm trying to devalue your hard work, but isn't this just a weak autobuyer?

 

Thanks for the reply... sounds very cool. So, uh, how would someone use it?

 

I put it on my php server... looks like the script checks for a restock but I can't really see the use of it... Whenever the script alerts you it should be too late for you to get any of the items.
Correct me if thats wrong...

 

How do we convert this into a program?

 

...It already is a program. Someone already explained how to run it. Try reading. "boredhacker2" isn't a great name for you if you don't even know what PHP is.

 

Okay.
This is really what i looked for.
can somebody tell me how to put this into a program or how to run it ...
sorry i'm a noob in such things.

 

What exactly are you looking for?

 

For a restock alerter. But i dont know how to use it.

 

You have to upload the php script onto a webhost and then go to the php page you uploaded

 

And how i can use it then?
:S
im just looking for a program that shows me if a shop restocks
