RE: [PHP] Picking random numbers

> OK I want to pick 5 random numbers from 1 to 200. Easy. > They must all be different. Not so easy. <? srand ((double) microtime() * 1000000); while (count($selectednumbers) < 5) { $randomnumber = rand(1, 200); if (!in_array($randomnumber, $selectednumbers)) { $selectednumbers[] = $randomnumber; } } //$selectednumbers is now an array with 5 items between 1 and 200. ?> This should work well enough to give you the general idea ... sorry if it doesn't, I grabbed some old code and modified it so I didn't embarrass myself too much by posting spaghetti code. :) Jason -- Jason Murray jasonm@melbourneit.com.au Web Developer, Melbourne IT "Work now, freak later!"
