As its name implies, NoRewindIterator doesn't invoke the "rewind" method when It reaches the end of the iterator. Let's demonstrate it by two examles. In this example the "rewind" method will be invoked after when the "foreache" reaches its end, so, we can repeat printing the same values as many times as we want: <?PHP $iterator = new ArrayIterator(['PHP', 'Python', 'Go']); foreach ($iterator as $item) { echo $item.PHP_EOL; } foreach ($iterator as $item) { echo $item.PHP_EOL; } ?> By using the NoRewindIterator, the "rewind" won't be invoked, so, we can't do as we did in previous example: <?PHP $iterator = new ArrayIterator(['PHP', 'Python', 'Go']); $iterator = new NoRewindIterator($iterator); foreach ($iterator as $item) { echo $item.PHP_EOL; } // doesn't do anything foreach ($iterator as $item) { echo $item.PHP_EOL; } ?> ---- Server IP: 45.112.84.4 Probable Submitter: 185.85.3.195 (proxied: 109.57.54.31) ---- Manual Page -- http://php.net/manual/en/class.norewinditerator.php Edit -- https://master.php.net/note/edit/124945 Del: integrated -- https://master.php.net/note/delete/124945/integrated Del: useless -- https://master.php.net/note/delete/124945/useless Del: bad code -- https://master.php.net/note/delete/124945/bad+code Del: spam -- https://master.php.net/note/delete/124945/spam Del: non-english -- https://master.php.net/note/delete/124945/non-english Del: in docs -- https://master.php.net/note/delete/124945/in+docs Del: other reasons-- https://master.php.net/note/delete/124945 Reject -- https://master.php.net/note/reject/124945 Search -- https://master.php.net/manage/user-notes.php
