Question

Trying to make this script go random. I tried variations of this string $banner_no = rand(1,$max)-1;

<div id="header_banner_ad">
    <?php
        $fcontents = join ('', file ('FILENAME'));
        $s_con = split("~",$fcontents);
        $banner_no = rand(1,(count($s_con)-1));
        echo $s_con[$banner_no];
    ?>
</div>

I’m not entirely sure what to do.

If you wan’t to select a random element from an array you could use array_rand()

Example:

$random = array_rand($s_con);
echo $s_con[$random];
