I am trying to fix up this website, but I know barely any php..

Here is my code:

Unsure, but if you are using PHP4 for some reason, then class variables should be defined with var.

There is no string literal (T_STRING) on line 11 in the file you posted. Are you sure the file you posted is the one the error messsage is complaining about?
