> when failing, as opposed to 0 and -1 in
   PHP/FI 2.0, respectively. The new behaviour allows for more
   logical code, like <VAR
CLASS="literal"
>$fp = fopen("/your/file") or
   fail("darn!");</VAR
>. Because PHP/FI 2.0 had no clear rules
   for what functions should return when they failed, most such
   scripts will probably have to be checked manually after using the
   2.0 to 3.0 convertor.
