using PHP inside HTML tags
Question
I'm in the middle of learning PHP right now and I'm stuck on this:
<?php
$links= array();
links[0]="https://www.google.co.in/";
links[1]="http://www.reddit.com/";
$n= rand(0,1);
$select= $links[$n];
?>
<body>
<a href="<?php echo $select; ?>">Random</a>
</body>
I want the page to redirect to either google or reddit randomly, but I don't understand what the problem is. Any solutions?

Missed $ for links variable ...Change code as
links[0]="https://www.google.co.in/";
links[1]="http://www.reddit.com/";
to
$links[0]="https://www.google.co.in/";
$links[1]="http://www.reddit.com/";

<?php
$links= array();
$links [0] = "https://www.google.co.in/";
$links [1] = "http://www.reddit.com/";
$n = rand (0, 1);
$select = $links [$n];
header ("Location: $select");

If you want to redirect automatically:
1- Use HTML META tag
<meta http-equiv="refresh" content="0;URL='<?php echo $select; ?>'">
2- or use PHP Header
header("Location: $select");
exit();
Full code:
<?php
$links= array();
$links [0] = "https://www.google.co.in/";
$links [1] = "http://www.reddit.com/";
$n = rand (0, 1);
$select = $links [$n];
header("Location: $select");
exit();
?>

<?php
$links = array(

"http://www.reddit.com/",
// ...
);
$randomLink = $links[rand(0, count($links)-1)];
header("Location: {$randomLink}");
exit();
