Even if an array has only one value, it is still an array and foreach will run it.

<?php
$arr[] = "I'm an array.";

if(is_array($arr))
{
    foreach($arr as $val)
    {
        echo $val;
    }
}
?>

The above code outputs:
I'm an array.
-------------------------------------
So if I use:

$query = "Select answer from answers where studentID='A123456789'"; 
$result = mysql_query($query,$connection) or die(mysql_error());
while($row = mysql_fetch_assoc($result))
{
	foreach($row as $answer)
	{
		echo $answer . "\n";
	}
}
I thought I would be able to print out each array element, but I am not getting any output.  Has anyone got a better idea?
