note 73077 added to function.mt-rand

a better (and likely faster) way to generate a random 6-digit hex string: <?php $num = mt_rand ( 0, 0xffffff ); // trust the library, love the library... $output = sprintf ( "%06x" , $num ); // muchas smoochas to you, PHP! return $output; ?> The mt_rand function won't give you a number outside the bounds you asked for -- no need to and-off the top bits -- and the sprintf function has params for length-padding & hexidecimal output. It's likely faster because most of the work is being done by the wicked fast C functions that PHP sits on top of, though YMMV in that dept. ---- Server IP: 64.71.164.2 Probable Submitter: 66.92.14.106 ---- Manual Page -- http://www.php.net/manual/en/function.mt-rand.php Edit -- https://master.php.net/note/edit/73077 Del: integrated -- https://master.php.net/note/delete/73077/integrated Del: useless -- https://master.php.net/note/delete/73077/useless Del: bad code -- https://master.php.net/note/delete/73077/bad+code Del: spam -- https://master.php.net/note/delete/73077/spam Del: non-english -- https://master.php.net/note/delete/73077/non-english Del: in docs -- https://master.php.net/note/delete/73077/in+docs Del: other reasons-- https://master.php.net/note/delete/73077 Reject -- https://master.php.net/note/reject/73077 Search -- https://master.php.net/manage/user-notes.php
