<?php

$urls[] = "url1";
$urls[] = "url2";
$urls[] = "url3";
$urls[] = "url4";
$urls[] = "url5";

srand ((double) microtime( )*1000000);
$random = rand(0,count($urls));

header("location:" . $urls[$random]);
exit;
?>

it sometimes redirects&rotate url,sometimes just show blank page....

perhaps count($urls) needs -1
count($urls)-1

when debugging you can print out url and random number vars and see where problem lays :2 cents:

yea thats what it is you need count($urls)-1 because count returns the number of elements in teh array but the array is indexed starting at 0

nope, that can result in -1 your first suggestion was ok

replace
$random = rand(0,count($urls));
with
$random = rand(0,count($urls)-1);

using array_rand is probably more straightforward... :2 cents:

Certainly takes out some minor overhead by calling count() manually for each parse. I'd suggest this as well for something as simple-tarded as mentioned.

Code:

<?php

$urls = array(

        'http://www.google.com',

        'http://www.msn.com',

        'http://www.bing.com',

        'http://www.webcrawler.com',

        'http://www.dogpile.com',

);

header("location: ". array_rand(array_flip($urls), 1));

?>

header("location: ". array_rand(array_flip($urls), 1));

?>

Or he could just do a shuffle.

Code:

<?php

$urls[] = "url1";

$urls[] = "url2";

$urls[] = "url3";

$urls[] = "url4";

$urls[] = "url5";



shuffle($urls);



header('location: '.$urls[0]);

?>

Gotta love how's there multiple solutions to the same thing.
