PHP：标头重定向，简单数组shuffle后[关闭]

Question

Ive got this simple php code:

<?php
  $links = array('http://link1.com', 'http://link2.com',);
  shuffle($links); 
  header("Location: $links[0]");
  exit;
?>

I want to randomize redirect link, using this simple array. Ive got two different servers on two different hostings. It works fine on one of these hosting and on localhost apache, but doesnt work on the second hosting. What might be the issue? Different php settings? Array and shuffle works, because I can echo te links, but there is a problem with header.

Do you have Try putting:

   session_start() 

at the beginning of your file? This worked for me a while ago
