[FX.php List] Current function

[Anders Monsen]

Hi Joel,

I think I see what you mean. So, it would be something like this  
instead, perhaps?

foreach($resultAcct['data'] as $key=>$current);
	$recordDetails = explode('.',$key);
	$recid = current($recordDetails);
	$nameFirst	= $current['Name_first'];

Either way it does seem like I use about the same amount of code in  
any of the options. I might be confusing the issue for myself by using  
the current function and naming a variable $current.

I've always wondered what the  [41.6] => Array referred to, so thank  
you clarifying this. It now make a heck of a lot more sense how we're  
able to get the $recid, $modid in the list() function, and why the  
above piece works. Previously I was just looking for something that  
worked; now I have a much better understanding of WHY it works.
