'instance' : 'static' : 'standalone'; }; $cls = Closure::bind($closure, null, 'A'); $cli = Closure::bind($closure, new A, 'A'); echo $closure() . PHP_EOL; // standalone echo $cls() . PHP_EOL; // static echo $cli() . PHP_EOL; // instance ?> ---- Server IP: 87.106.1.137 Probable Submitter: 188.108.65.208 ---- Manual Page -- http://php.net/manual/en/class.closure.php Edit -- https://master.php.net/note/edit/111982 Del: integrated -- https://master.php.net/note/delete/111982/integrated Del: useless -- https://master.php.net/note/delete/111982/useless Del: bad code -- https://master.php.net/note/delete/111982/bad+code Del: spam -- https://master.php.net/note/delete/111982/spam Del: non-english -- https://master.php.net/note/delete/111982/non-english Del: in docs -- https://master.php.net/note/delete/111982/in+docs Del: other reasons-- https://master.php.net/note/delete/111982 Reject -- https://master.php.net/note/reject/111982 Search -- https://master.php.net/manage/user-notes.php
