Extract Form Field Names When They're Not Known In Advance

I have a page with a form which has automatically generated fields, (which come from mysql column names). There could be any number of these fields, and I have no way of knowing exactly what they're called. But obviously I need to know their names, in order to extract their values on the submission page.

They are either of the form c%status#, e%status# or t%status#

% is a number between 1 and 13 (inclusive)
# could be anything in the pattern 01, 02, 03, with no limit

Eg: fields could be c2status03 and e4status07, but I don't know this in advance. These would be generated on the fly from mysql.

But on the submission page I need to be able to generate the code $var1=$_POST['c2status'] and $var2=$_POST['e4status07']

Is there a way for me to somehow get these names so I can extract their values on the submission page? Or have I hit a dead end?
