Redirect function with permanent 301 redirect support

abstract 
Here is an example of simple function ae_redir() for HTTP redirect. It supports relative site paths and permanent(seo-compatible) redirects. There is also function ae_redir_die() which stops execution of script after sending redirect.
compatible 
  • PHP 4.1.0 or higher
  • PHP 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)

    source code: php
    <?php 
    function ae_redir($uri$isperm=false)
    {
        if (
    $isperm)
            
    header("HTTP/1.1 301 Moved Permanently");

        if ((
    substr($uri05) != 'http:') &&
            (
    substr($uri06) != '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:

    source code: php
    <?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 

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