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

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
