note 116525 added to function.extract

Note that extract() will only create or overwrite variables in the current scope, so <? function test(){ $a=Array('b'=>1,'c'=>2); extract($a); } test(); exit("$b"); ?> will produce no output, whereas <? function test(){ global $b; $a=Array('b'=>1,'c'=>2); extract($a); } test(); exit("$b"); ?> will output 1. ---- Server IP: 87.124.126.49 Probable Submitter: 2.31.64.172 ---- Manual Page -- http://php.net/manual/en/function.extract.php Edit -- https://master.php.net/note/edit/116525 Del: integrated -- https://master.php.net/note/delete/116525/integrated Del: useless -- https://master.php.net/note/delete/116525/useless Del: bad code -- https://master.php.net/note/delete/116525/bad+code Del: spam -- https://master.php.net/note/delete/116525/spam Del: non-english -- https://master.php.net/note/delete/116525/non-english Del: in docs -- https://master.php.net/note/delete/116525/in+docs Del: other reasons-- https://master.php.net/note/delete/116525 Reject -- https://master.php.net/note/reject/116525 Search -- https://master.php.net/manage/user-notes.php
