 Hello

Say I have a welcome page and 2 other pages, a.htm and b.htm.

How can I guide visitors, alternately to a and to b?

Cheers

Geoff

Put a gun to their head?

Not enough information, and not sure it is a good idea.

Do you mean alternated links from one visitor to the next? if so that
would require recording the which link was last presented on the server.

Or do you mean alternate for a single visitor upon subsequent visits?
That would require a persistent cookie.

A much simpler method would be a link randomizer.

<?php

$links = array('a.html','b.html','c.html','d.html');
$last=count($links)-1;
$link=$links[rand(0,$last)];

echo "<a href=\"$link\">Mystery Tour</a>";

?>

Thanks Joanathan,

when I use the above I get

Mystery Tour"; ?>

I must be missing something?

Cheers

1) your server must support php

2) the page is named with a ".php" extension (normally for most server
setups)

3) attention to the escaped quotes

echo "<a href=\"$link\">Mystery Tour</a>";
^ ^
or concatenate with single quotes

echo '<a href="' . $link . '">Mystery Tour</a>';

Or simply

echo "<a href='$link'>Mystery Tour</a>";

HTML also allows single quotes, which avoids both the ugly escaping and
concatenations in the script.
