ListGetAt is a really cool ColdFusion function. Is great for grabbing values from a comma separated list (or any other delimited list)! I use this function a lot instead of the explode function. They essentially do the same, but using this function removes 1 step. Instead of first exploding the then getting the value for your array key. For the seasoned PHP coder and everyone else, the position will always start at 1 NOT 0. Also, the default delimiter is a ','(comma).
The Function:
function ListGetAt($list,$position,$delimiter=",")
{
$bit = explode($delimiter,$list);
return $bit[($position-1)];
}
Usage:
Using the ListGetAt function is quite easy!
<?php
$list = "apples,oranges,grapes";
echo ListGetAt($list,1);
?>
The resulting out put would be: apples
<?php
$list = "apples+oranges+grapes";
echo ListGetAt($list,2,"+");
?>
The resulting out put would be: oranges
