note 56189 added to function.include

When many files need to include the same file then you might end up with an error saying class/function already defined... To avoid this, you can use the following trick: Add the following in your include file (NOTE: give a unique defined name for each include file): if (!defined("GLOBALS_DEFINED")) { define("GLOBALS_DEFINED", 1); //... Place code and definitions here } // End of if (!defined(... For example: ----------------------- globals.php <?php if (!defined("GLOBALS_DEFINED")) { define("GLOBALS_DEFINED", 1); class CMessages { //... Place code here } // End of class definition } // End of if (!defined(... ?> ----------------------- test.php <?php include("globals.php"); //... Place Code here ----------------------- main.php <?php include("test.php"); include("globals.php"); //... Place Code here ?> ----------------------- ---- Manual Page -- http://www.php.net/manual/en/function.include.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+56189 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+56189&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+56189&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+56189&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+56189&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+56189&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+56189&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+56189&report=yes Search -- http://master.php.net/manage/user-notes.php
