It is not an error message, it is a *warning*.

It is pointless and confusing for people accustomed to writing PHP code to
put the RHS into parentheses here.

Look closely at that warning. This approach is not going to work reliably
because the HTTP request URI does not need to have anything to do with the
file path of the resource. In fact, there does not even need to be a real
file for a URI, the served content could have been generated entirely by PHP
(and usually is). As a result, in those cases filemtime() returns FALSE …

> print(date("F j, Y - h:i A", $last_modified));

… which date() converts to 0 (UNIX epoch) – as it expects an int (UNIX
timestamp), not a boolean value, for the second argument – and formats that
accordingly to “December 31, 1969” (not “January 1, 1970 - 12:00 AM”
probably because of timezone issues), which is then send to stdout by
print(). (You should use “echo” instead, unless in an expression where you
need “print”’s return value. Think sh, not perl.)

(I am in UTC+2 now because of European Summer Time, and date.timezone is set
to “Europe/Zurich”; the latter would account for the one-hour advance.)

You might be looking for filemtime(__FILE__) instead.
