Help with plugin array and option settings

That's actually what I'd expect to see if the stristr() was never matching anything. Maybe try this:

...
$fp = fopen("output.txt", "w"); 
fwrite($fp, "User Agent: '" . $user_agent . "'\n"); 
for ($i=0;$i<$n;$i++) {
fwrite($fp, "bots[$i]: '" . $bots[$i] . "'\n"); 
if (strstr($user_agent,$bots[$i])) 
{
    fwrite($fp, "Matched.\n"); 
    banned_redirect('www.google.com.cn/search?hl=zh-CN&q=crystal+light+centrum&meta=');
}
} 
    fwrite($fp, "\nNothing matched.\n"); 
}
