[PHP] Variable name as a string

[ioannes]

Could someone tell me how to get the name of a variable as a string.  
This would be useful in form submission with multiple check-boxes to 
match against database records.  At the moment I use ${"var".$ID[$x]} or 
someting like that to go through all the possible matches, but it would 
be quicker to explode the name of a checkbox like a string like cb_1 to 
match to record 1 etc.

There is some reason I do not use the value of the check box, but I can't 
remember it now!
