note 93715 added to control-structures.foreach

This is a really silly example of how you can implement foreach for objects in a really crazy way... It's not something you should use... <?php /** * Same as foreach, for objects... * * @param object|array $_collection * @param callback $_lambda * @param mixed $_data optional * @return void */ function loop($_collection, $_lambda, $_data = null) { if(is_array($_collection)) { foreach($_collection as $key => $value) { if(is_null($_data)) $_lambda($key, $value); else $_lambda($key, $value, $_data); } } elseif(is_object($_collection)) { $iter = $_collection->getIterator(); $iter->rewind(); while($iter->valid()) { if(is_null($_data)) $_lambda($iter->key(), $iter->current()); else $_lambda($iter->key(), $iter->current(), $_data); $iter->next(); } } else trigger_error('Only Accepts Objects or Arrays', E_USER_ERROR); } // and this is how to use it... $data = "some random data"; // you can place $this here loop(new ArrayObject(array(1,2,3,4)), function(&$_key, &$_value, &$_data) { echo $_key.$_value.$_data; }, $data); ?> ---- Server IP: 212.63.193.10 Probable Submitter: 81.235.227.65 ---- Manual Page -- http://www.php.net/manual/en/control-structures.foreach.php Edit -- https://master.php.net/note/edit/93715 Del: integrated -- https://master.php.net/note/delete/93715/integrated Del: useless -- https://master.php.net/note/delete/93715/useless Del: bad code -- https://master.php.net/note/delete/93715/bad+code Del: spam -- https://master.php.net/note/delete/93715/spam Del: non-english -- https://master.php.net/note/delete/93715/non-english Del: in docs -- https://master.php.net/note/delete/93715/in+docs Del: other reasons-- https://master.php.net/note/delete/93715 Reject -- https://master.php.net/note/reject/93715 Search -- https://master.php.net/manage/user-notes.php
