note 107427 added to control-structures.for

Looping through letters is possible. I'm amazed at how few people know that. for($col = 'R'; $col != 'AD'; $col++) { echo $col.' '; } returns: R S T U V W X Y Z AA AB AC Take note that you can't use $col < 'AD'. It only works with != Very convenient when working with excel columns. ---- Server IP: 69.147.83.197 Probable Submitter: 78.22.36.128 ---- Manual Page -- http://www.php.net/manual/en/control-structures.for.php Edit -- https://master.php.net/note/edit/107427 Del: integrated -- https://master.php.net/note/delete/107427/integrated Del: useless -- https://master.php.net/note/delete/107427/useless Del: bad code -- https://master.php.net/note/delete/107427/bad+code Del: spam -- https://master.php.net/note/delete/107427/spam Del: non-english -- https://master.php.net/note/delete/107427/non-english Del: in docs -- https://master.php.net/note/delete/107427/in+docs Del: other reasons-- https://master.php.net/note/delete/107427 Reject -- https://master.php.net/note/reject/107427 Search -- https://master.php.net/manage/user-notes.php
