PHP - Header Location not working on mobile?

Question

Expample Link: http://link.bisnis-id.com/?go=google

<?php if(isset($_GET['go'])) { ?>
<?php $link_id = $_GET['go']; ?> <!-- output = google -->

<!-- Short explanation: "google" is generating a link for google website -->
<?php $link_url = "https://www.google.com"; ?>

<?php header("Location: $link_url"); ?>
<?php exit; ?>
<?php } ?>

That link will redirect to https://www.google.com , but It is not redirecting when I access on mobile browser.

Answer 1

You can't output even a single output before the header.Also you should have only one starting and ending for this header.You can use ob_start() to. use the code below

    <?php if(isset($_GET['go'])) { 

     $link_id = $_GET['go'];
    $link_url = "https://www.google.com";
    header("Location: $link_url");
     exit;
   } 
?>

Hope this helps you

Answer 2

You do not have to break the PHP block.

Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP.

<?php if(isset($_GET['go'])) {
    $link_id = $_GET['go']; //output = google 

    //Short explanation: "google" is generating a link for google website 
    $link_url = "https://www.google.com"; 

    header("Location: $link_url");
    exit;
