PHP 4.1.0 or higherPHP 5
ae_redir function uses two arguments:
- distination URL or relative path
- optional argument — boolean flag for sending 301 permanent redirect
301 permanent redirect is used by search engines (like Google) to associate different
URLs with the same page(and pagerank)
<?php
function ae_redir($uri, $isperm=false)
{
if ($isperm)
header("HTTP/1.1 301 Moved Permanently");
if ((substr($uri, 0, 5) != 'http:') &&
(substr($uri, 0, 6) != 'https:'))
header("Location: http://".$_SERVER['HTTP_HOST'].$uri);
else
header("Location: {$uri}");
}
function ae_redir_die($url, $isperm=false)
{ ae_redir($url, $isperm); exit(); }
?>
Usage example:
<?php
// Example 1:
ae_redir("http://www.apple.com");
// Redirect to www.apple.com and continue executing code
...
// Example 2:
ae_redir("https://www.gmail.com");
// HTTPS redirects are also supported
...
// Example 2:
ae_redir("http://www.microsoft.com", true);
// Send permanent redirect to www.anyexample.com
// For example, you could register www.microsoft-another-domain.com
// and put this code to index.php to tell search engines
// that www.microsoft-another-domain.com is just another domain for
// microsoft.com
...
// Example 3:
ae_redir_die("http://www.anyexample.com");
// Redirect to www.anyexample.com and stop executing
...
// Example 4:
ae_redir_die("/error.php?msg=error");
// Redirect to yoursite.url/error.php?msg=error and end program
?>

Most of the time you should use ae_redir_die() function to avoid execution of superfluous code.
