note 60243 added to language.variables.scope

Consider the files and their content below: --index.php <?php include_once("inc2.php"); include_once("inc1.php"); goer(); echo "var 1: ".$dd_myvar1.'<br>'; echo "var 2: ".$dd_myvar2.'<br>'; echo "var 3: ".$dd_myvar3.'<br>'; ?> --inc1.php: <?php $dd_myvar1 = "inc1"; ?> --inc2.php: <?php $dd_myvar2 = "inc2"; function goer() { include_once("inc3.php"); } ?> --inc3.php: <?php $dd_myvar3 = "inc3"; function roer() { die("ran roer"); } ?> opening index.php in your browser will produce: var 1: inc1 var 2: inc2 var 3: It took me a while to work out why var 3 was not showing. From this simplified example it is obvious that because the include statement in inc2.php is in a function, it will only apply to that function (taking the include function out of the function will show var3). Now, if we add roer(); as the last line to index.php and then open it in the browser then you will see: inc var 1: inc1 inc var 2: inc2 inc var 3: ran roer This may be confusing. While the variables loaded from goer could not be seen, the function loaded was available in index.php. ---- Manual Page -- http://www.php.net/manual/en/language.variables.scope.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60243 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60243&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60243&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60243&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60243&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60243&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60243&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60243&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60243&report=yes Search -- http://master.php.net/manage/user-notes.php
