How to prevent includes from attempting redefinitions

[Tim Tyler]

I import library routines using include(...);

However, importing library routines that themselves use other library routines
easily leads to repeated declarations - which give errors of the form:

``Fatal error: Cannot redeclare method_name() (previously declared in
/usr/local/home/httpd/vhtdocs/timtyler/php/table_highlight _border.inc.php :2)
in /usr/local/home/httpd/vhtdocs/timtyler/php/table_highlight _border.inc.php
on line 11''

Should I try setting flags - and doing things conditionally?

What is the best approach for working around this issue?

Try include_once() that way PHP will keep track of if it has included
the file already and won't try again.

You can use include_once() or else perform your includes from within the
parent calling script (as opposed to having one include inside another
included function/script), place what you want to include at the very
begining of your script
