But the seemingly fastest way contains a pitfall for beginners who just use it because it is fast and fast is cool ;) Walking through an array with next() will cut of the first entry, as this is the way next() works ;) If you really need to do it this way, make sure your array contains an empty entry at the beginning. Another way would be to use <?php while ($this = current($array) ){ do_something($this); next($array); } ?> There is an impact on speed for sure but I did not test it. I would advise to stick with conventional methods because current(),next() in while loops is too error prone for me. ---- Manual Page -- http://www.php.net/manual/en/control-structures.while.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+50900 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+50900&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+50900&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+50900&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+50900&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+50900&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+50900&report=yes Search -- http://master.php.net/manage/user-notes.php
