External variables in a function I needed to access dynamically-created variables from an included file within a helper function. Because the list of $path_* variables I needed to access from the other file is itself dynamic, I didn't want to have to declare all possible variables within the function, and I was concerned at the overhead of declaring =all= members of $GLOBALS[] as global. However the following code worked for me: function makePath($root, $atom) { $pos = strrpos($atom, '/'); if ($pos === false) { global ${'path_'.$atom}; $path = ${'path_'.$atom}; } else { global ${'path_'.substr($atom, 0, $pos)}; $path = ${'path_'.substr($atom, 0, $pos)}; } if ($path) return ($pos === false) ? $root.$path : $root.$path.substr($atom, $pos + 1); else return NULL; } Regards, ::Leigh http://www.else.co.nz/ ---- Server IP: 203.89.181.186 Probable Submitter: 118.93.33.219 ---- Manual Page -- http://www.php.net/manual/en/language.variables.scope.php Edit -- https://master.php.net/note/edit/89872 Del: integrated -- https://master.php.net/note/delete/89872/integrated Del: useless -- https://master.php.net/note/delete/89872/useless Del: bad code -- https://master.php.net/note/delete/89872/bad+code Del: spam -- https://master.php.net/note/delete/89872/spam Del: non-english -- https://master.php.net/note/delete/89872/non-english Del: in docs -- https://master.php.net/note/delete/89872/in+docs Del: other reasons-- https://master.php.net/note/delete/89872 Reject -- https://master.php.net/note/reject/89872 Search -- https://master.php.net/manage/user-notes.php
