You made a mistake: $licz < $numofletters , but it must be $licz <= $numofletters <?php function random_letters ($numofletters) { if (!isset($numofletters)) $numofletters = 10; // if $numofletters is not specified sets to 10 letters $literki = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'R', 'S', 'T', 'U', 'W'); $ilosc_literek = count($literki); for ($licz = 0; $licz < $numofletters; $licz++) { $rand = rand(0, $ilosc_literek-1); $vercode = $vercode.$literki[$rand]; } } ?> ---- Server IP: 212.124.37.9 Probable Submitter: 78.50.217.225 ---- Manual Page -- http://www.php.net/manual/en/function.rand.php Edit -- https://master.php.net/note/edit/83702 Del: integrated -- https://master.php.net/note/delete/83702/integrated Del: useless -- https://master.php.net/note/delete/83702/useless Del: bad code -- https://master.php.net/note/delete/83702/bad+code Del: spam -- https://master.php.net/note/delete/83702/spam Del: non-english -- https://master.php.net/note/delete/83702/non-english Del: in docs -- https://master.php.net/note/delete/83702/in+docs Del: other reasons-- https://master.php.net/note/delete/83702 Reject -- https://master.php.net/note/reject/83702 Search -- https://master.php.net/manage/user-notes.php
