dynamic function calls!

[dreadkhan]

I need a hand in implementing dynamic function calls.

I would like to keep an array of strings, that map to function names like...

global $myarray[3]

$myarray[0] = "function1"

$myarray[1] = "function2"

$myarray[2] = "function3"

this is for an irc bot, where i would have a help command return this array of available commands. then when you send a command, have it call that function.

so when someone in irc says.. function1

it would iterate throguh the available strings in this array, realize that function1 exists and attempt to invoke a function called...function1.

so basically, given a string that represents the name of a function, how can i invoke that function?

I also need to have the ability to check if the function exists, is a try catch that best way to accomplish that?

Call(), check the help file.

[dreadkhan]

Call(), check the help file.

thats incredibly useful, thank you.

how can i check if a function exists before using Call()?

if the function doesn't exists @error will be set to 0xDEAD.

That error code is win.

[monoceres]

That error code is win.

MsgBox(Call(Eval("")),"Win!",Hex(@error*65536+@extended,8))

I wouldn't call staying up at 2 am when you should be sleeping free time.

lol that is an awesome error message.. even when you don't WANT to see one... lol

Sets @error to 0xDEAD and @extended to 0xBEEF if the function does not exist or invalid number of parameters.

0xBEEF... WTF hahahaha SWEET i never noticed that before

and
