Hello $variable, whats your name?

I would like to know if there is a way to determine the name of a variable. Example: I have the variable $firstname, with a value of Jon I want to be able to echo name_of_variable : value_of_variable; So the user would see firstname : Jon I want to be able to do this without knowing what variables will be passed to the PHP script in advance. Any help is appreciated in advance. <Jon> =============================== And shepards we shall be For thee, my lord, for thee For thou hath descended forth from thy hands That our feats may swiftly carry out thy command We will flow a river forth unto thee And teaming with souls shall it ever be... =============================== http://jcampbell.blacklightning.net
