If you can access the "field" (element would be a better word in my
opinion), you can save/store it in some variable.
Suppose you have some array (created from XML, or whatever):
$someArr = array();
$someArr[0] = array(22,55,99);
$someArr[1] = array("Joe","Will","Smith");
etc.
Now, if you need to store, say, the second element in $someArr[1],
simply do so:
....yourcode.....
$rememberMe = $someArr[1][1]; // Will contain "Will"
....yourcode.....
If that doesn't help you, post a more detailed description of your problem.
