This function has a useful undocumented feature - the defaults are set in such a way that calling it with no parameters returns the full URL of the page being accessed.

If you need to access the url to the current script you should examine $_SERVER['REQUEST_URI'].

Using an undocumented feature that gives the same functionality as existing PHP library calls is reckless.

Although I've never used this function, based on the documentation it seems that the above code should also include the following:

<?php
   
if ( ! is_array( $url ) ) // Added - Randy
    // Parse the original URL
       
$parse_url = parse_url($url);
       
// allow parts to be a url Added - Randy
   
if ( ! is_array( $parts ) )
       
$parts = parse_url( $parts );
?>

To those that want to use http_build_url() without parameters to get the canonical page URL, be aware that this function seem to consider the equivalent of SCRIPT_NAME for the path instead of REQUEST_URI.

For example, if /example serve info.php (you can do this with mod_rewrite in Apache for example), while accessing http://example.com/example?test=1 this function will return http://example.com/info.php?test=1 instead of the URL the user see.  This could lead to obvious problems if you build other URL from this.

So like another comment say, it is reckless to use that undocumented feature.  Instead here is what I suggest:

<?php
function get_request_url()
{
    return
get_request_scheme() . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
}

function
get_request_scheme()
{
    return (isset(
$_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off') ? 'https' : 'http';
}
?>

So you used parse_url(...) and looking to put it back together and seeing if this function will do? 

You may have seen some glue* functions that will rebuild the url with the parts that you have.  Try this:

<?php

   $parts
= parse_url($uri);
  
/* do your magic here on $parts */
  
$uri = http_build_url('', $parts);
?>

Notice the first param is empty string.  It also works with NULL and array() as well.
