php debug

[jwzumwalt]

Several months back I saw code that showed how to have all the variable information linked to a small "+" at the top left corner of a web page. I have looked in vain for this code which I think I ran accross while doing a google search for "php print array". Anyone know where I might get this code?
Thanks - jz
