I'm trying out to figure this line of code.
if ($POST[$p] == $POST[$p.'initvalue'])
what does the $p.'initvalue' mean? Please help!
If $p contained the string "wibble" then it would test to see if ($POST['wibble']==$POST['wibbleinitvalue']). It's just the same string concatenation operator that's used everywhere else that strings are joined together.
Ohhh! It's a concatenation. Now I get it! Thanks!!!
