note 92868 added to language.variables.scope

For nested functions: This is probably obvious to most people, but global always refers to the variable in the global (top level) variable of that name, not just a variable in a higher-level scope. So this will not work: <?php // $var1 is not declared in the global scope function a($var1){ function b(){ global $var1; echo $var1; // there is no var1 in the global scope so nothing to echo } b(); } a('hello'); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 65.46.73.222 ---- Manual Page -- http://www.php.net/manual/en/language.variables.scope.php Edit -- https://master.php.net/note/edit/92868 Del: integrated -- https://master.php.net/note/delete/92868/integrated Del: useless -- https://master.php.net/note/delete/92868/useless Del: bad code -- https://master.php.net/note/delete/92868/bad+code Del: spam -- https://master.php.net/note/delete/92868/spam Del: non-english -- https://master.php.net/note/delete/92868/non-english Del: in docs -- https://master.php.net/note/delete/92868/in+docs Del: other reasons-- https://master.php.net/note/delete/92868 Reject -- https://master.php.net/note/reject/92868 Search -- https://master.php.net/manage/user-notes.php
