Help with a Foreach() Loop

[cooldude832]

This is my array: (n represents a counting number of array values

 

$page[$currentpage][n]:

                                1

                                2

                                3

                                4

$currentpage is produced from a get var in the URL

I then say foreach($page[$currentpage] as $value)

 

it works fine if the limit isn't messed with manually, but when a users makes $limit into a different number outside the limits of $page[$currentpage] or to a string my foreach errors out.  Is there a way to say if it will error out don't do it without testing the var $currentpage. 

like:

foreach($n as $v) or die ('error');
