Bug #18557: array_rand() with mt_srand() not giving me random values

From: naintara@ndf.vsnl.net.in Operating system: Windows 2000 Professional Server PHP version: 4.2.1 PHP Bug Type: Arrays related Bug description: array_rand() with mt_srand() not giving me random values I have an array of 26 characters. I want three random values from the array, I use the following: $rand_al = array_rand ($arralpha, 3); Prob: I get the same characters each and every time. What I am doing: First I seed the generator with mt_srand ((double) microtime() * 1000000); I fill my array $arralpha with values, and use the array_rand() function to return me random indexes $rand_al = array_rand ($arralpha, 3); On echoing the values at those indexes, I got the same values each time Workaround: The way I am handling it right now is generating random values using mt_rand(0,25) and using those random values as the array subscripts. This method gives me random values. Additional Info: mt_getrandmax() returned 2147483647. -- Edit bug report at http://bugs.php.net/?id=18557&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=18557&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=18557&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=18557&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=18557&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=18557&r=support Expected behavior: http://bugs.php.net/fix.php?id=18557&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=18557&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=18557&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=18557&r=globals
