[Blackjack] What we have to do ?

We have to create the game in php using Javascript and HTML or simply create a PHP library ?

I think is most useful to create an application but I don't understand your blackjack rules explanation and contest goals.

from the rules:


from the other contests they have done here, you are not supposed to have any output. it doesnt say in the rules, but if this applies, the blackjacklib file should do the only output that happens

Correct...your script does not output anything. You simply interface with the library.

We have to create an interface for playing black jack and we must use the blackjacklib.php ?
True ?

No...you will make a script that automatically plays the game of blackjack and it must interface with the dealer (the library). Your script must follow all the rules on the rules page.

Maybe this will help:

Use PHP as a programming language, not a web scripting lanugage, to create an artificial intelligence that plays the game of blackjack using the rules specified on the page. Your script takes no input from the user, and uses the library interface to perform actions like hitting and standing.

If you download the library, there's a file included in the .zip named miniplay.php. You're supposed to make a similar script, except that you need to make it decide (much) better on what to play.
