^Z is *not* EOF, and never was under Unix-like systems.  This is not
the problem.  You should get rid of the ^Z if it's there, though.

It's been a while since I did any fiddling with PHP, but this syntax
may not be entirely right.  The $[Table] looks ... odd, since PHP uses
something similar to Perl syntax and I'd expect a thing like
$array[$table] there.  But they may have changed things between PHP3
and now.

Start vim or emacs, then.  (There are 2 text editors:  vim and emacs.  All
others are neither powerful enough nor ubiquitous enough.)  Also have a look
at line 149.  If you have a missing ; or another missing char, that may 
cause errors to be reported on the following line instead of the line with 
the problem.  HTH anyway,
