note 100737 added to function.include-once

Be aware that variable expansions in include file occurs only once (same behaviour in require_once ), for example: # test.inc <?php $b = $a; ?> # test.php <?php $a = 1; include_once('test.inc'); echo "b value is $b<br>"; $a = 5; include_once('test.inc'); echo "b new value is $b<br>"; ?> // output is b value is 1 b new value is 1 My personal policy is do not include executable code in include_once (just classes, function,etc), unless there are variables you don't expect to change over script lifetime i.e. config vars or defines ---- Server IP: 200.6.154.201 Probable Submitter: 201.242.161.67 ---- Manual Page -- http://www.php.net/manual/en/function.include-once.php Edit -- https://master.php.net/note/edit/100737 Del: integrated -- https://master.php.net/note/delete/100737/integrated Del: useless -- https://master.php.net/note/delete/100737/useless Del: bad code -- https://master.php.net/note/delete/100737/bad+code Del: spam -- https://master.php.net/note/delete/100737/spam Del: non-english -- https://master.php.net/note/delete/100737/non-english Del: in docs -- https://master.php.net/note/delete/100737/in+docs Del: other reasons-- https://master.php.net/note/delete/100737 Reject -- https://master.php.net/note/reject/100737 Search -- https://master.php.net/manage/user-notes.php
