I'm ready to rip my hair out!

I have a form which submits to a script to generate an image using the info 
on the form.

I am trying to center the text over the image, and this application 
requires the use of variable-width fonts.  So I am using a very basic regex 
to check for an all-caps string in order to adjust the placement of the 
text in the image.

I don't know what is causing this, but the regex seems to get "stuck" 
holding a particular value.  If you type in a string in all lower case 
after changing the regex, it works fine.  It may work 10 times in a 
row.  But then after some seemingly arbitrary number of submissions, the 
value of the variable $uo in the script snippet below will not change.

I am stumped - if anyone has any insight into this I'd appreciate it.

You can view the script in action here: http://toolshed51.dhs.org/~josh/

The script prints the value of $uo preceding the input text.


Code snip:

                         $string = ${"line" . $x};
                         $string = stripslashes($string);
                         if(ereg("^([A-Z])*$", "$string"))
                                 $uo = 1;
                         } else
                                 $uo = 2;
