[SOLVED] while (list(,$n_fred) - what does nothing before the comma mean?

[scanreg]

I found the following:

 

while (list(,$n_fred)

 

What does it mean when there is nothing in front of the comma for the list function? :

 

list(,$n_fred)

 

Many thanks

It just means you discard the first element in the array you are using list on.

Great, thanks
