note 98811 added to language.variables.scope

Please note for using global variable in child functions: This won't work correctly... <?php function foo(){ $f_a = 'a'; function bar(){ global $f_a; echo '"f_a" in BAR is: ' . $f_a . '<br />'; // doesn't work, var is empty! } bar(); echo '"f_a" in FOO is: ' . $f_a . '<br />'; } ?> This will... <?php function foo(){ global $f_a; // <- Notice to this $f_a = 'a'; function bar(){ global $f_a; echo '"f_a" in BAR is: ' . $f_a . '<br />'; // work!, var is 'a' } bar(); echo '"f_a" in FOO is: ' . $f_a . '<br />'; } ---- Server IP: 69.147.83.197 Probable Submitter: 188.158.165.233 ---- Manual Page -- http://www.php.net/manual/en/language.variables.scope.php Edit -- https://master.php.net/note/edit/98811 Del: integrated -- https://master.php.net/note/delete/98811/integrated Del: useless -- https://master.php.net/note/delete/98811/useless Del: bad code -- https://master.php.net/note/delete/98811/bad+code Del: spam -- https://master.php.net/note/delete/98811/spam Del: non-english -- https://master.php.net/note/delete/98811/non-english Del: in docs -- https://master.php.net/note/delete/98811/in+docs Del: other reasons-- https://master.php.net/note/delete/98811 Reject -- https://master.php.net/note/reject/98811 Search -- https://master.php.net/manage/user-notes.php
