Chris,

Thank you very much. urlencode/urldecode works. It never occured to me to
use this technique with the POST method, but it works and solves this issue
of getting back exactly what you preset a form variable to be.

Interestingly, htmlentities doesn't seem to work for me as 

htmlentities($a) is not equal to htmlentities($_post['q1']) 

It seems like it should work (as all characters with entity equivalents
should be translated), but it doesn't for me even exploring the various
quoting options of this function.

My issue is that I have no idea of what people are going to put into the $a
string.  It may contain entities or not.  All I need to know is if I got
back the exact same string after posting which is where I ran into this
issue.

On a side note,It also seems to me that the "text" form elements are going
to present special issues like the one mentioned by Rahmin since you are not
dealing with preset values.  

Thanks again for your help.

Mike
