[PHP] T_PAAMAYIM_NEKUDOTAYIM

[Unknown Unknown]

I was working with objects, and suddenly i got this error:
*Parse error*: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM in *
D:\Apache\Apache(re)\Apache2\htdocs\Include.php* on line *11*
is this like a bug in PHP or is it a valid error?
thanks in advance
