note 69611 added to language.variables.scope

Using the global keyword inside a function to define a variable is essentially the same as passing the variable by reference as a parameter: somefunction(){ global $var; } is the same as: somefunction(& $a) { } The advantage to using the keyword is if you have a long list of variables needed by the function - you dont have to pass them every time you call the function. ---- Server IP: 64.71.164.2 Probable Submitter: 198.151.217.26 ---- Manual Page -- http://www.php.net/manual/en/language.variables.scope.php Edit -- https://master.php.net/note/edit/69611 Del: integrated -- https://master.php.net/note/delete/69611/integrated Del: useless -- https://master.php.net/note/delete/69611/useless Del: bad code -- https://master.php.net/note/delete/69611/bad+code Del: spam -- https://master.php.net/note/delete/69611/spam Del: non-english -- https://master.php.net/note/delete/69611/non-english Del: in docs -- https://master.php.net/note/delete/69611/in+docs Del: other reasons-- https://master.php.net/note/delete/69611 Reject -- https://master.php.net/note/reject/69611 Search -- https://master.php.net/manage/user-notes.php
