parse_url (PHP 3, PHP 4 ) parse_url -- Rozebrat URL a vrátit její komponenty Popisarray parse_url ( string url)
Tato funkce vrátí asociativní pole všech komponent URL přítomnych v
url. Ty mohou být: "scheme", "host", "port",
"user", "pass", "path", "query" a "fragment".

It gets better...
parse_str($_SERVER['QUERY_STRING']);
though you might flinch at random names from the URI query string showing up as variables. Safer to secure them in a hash table, eg
parse_str($_SERVER['QUERY_STRING'],$vars);
$lang = $vars['lang'];
echo "Your language is $lang";

Regarding claude_minette at hotmail dot com note about variables from a previous page, here's an easier way:
$tab = parse_url($_SERVER['HTTP_REFERER']);
parse_str($tab['query']);

if you need, (for a reason or another), to get back the query as variables in your new page, use this... ;-)
$origin=$_SERVER["HTTP_REFERER"];
$tab=parse_url($origin);
$query=$tab["query"];
$variables=explode("&",$query);
for ($i=0;$i<=count($variables);$i++){
$tab=explode("=",$variables[$i]);
$$tab[0]=$tab[1];
}
It seems to be working... ;-)

My version of the glue function, and adding/removing parts of query strings...
function unparse_url($parts_arr) {
if (strcmp($parts_arr['scheme'], '') != 0) {
$ret_url = $parts_arr['scheme'] . '://';
}
$ret_url .= $parts_arr['user'];
if (strcmp($parts_arr['pass'], '') != 0) {
$ret_url .= ':' . $parts_arr['pass'];
}
if ((strcmp($parts_arr['user'], '') != 0) || (strcmp($parts_arr['pass'], '') != 0)) {
$ret_url .= '@';
}
$ret_url .= $parts_arr['host'];
if (strcmp($parts_arr['port'], '') != 0) {
$ret_url .= ':' . $parts_arr['port'];
}
$ret_url .= $parts_arr['path'];
if (strcmp($parts_arr['query'], '') != 0) {
$ret_url .= '?' . $parts_arr['query'];
}
if (strcmp($parts_arr['fragment'], '') != 0) {
$ret_url .= '#' . $parts_arr['fragment'];
}
return $ret_url;
}
function add_query_arg($url, $arg, $val) {
$parts_arr = parse_url($url);
if (strcmp($parts_arr['query'], '') != 0) $parts_arr['query'] .= '&';
$parts_arr['query'] .= $arg . '=' . $val;
return unparse_url($parts_arr);
}
function remove_query_arg($url, $arg) {
$parts_arr = parse_url($url);
if (!strcmp($parts_arr['query'], '')) return $url;
$query_arr = explode('&', $parts_arr['query']);
foreach ($query_arr as $k => $v) {
if ((preg_match('/^'.$arg.'=/', $v)) || (preg_match('/^'.$arg.'$/', $v))) {
unset($query_arr[$k]);
}
}
$parts_arr['query'] = implode('&', $query_arr);
return unparse_url($parts_arr);

This is a small update for Steve's function. It removes the Argument even if its repeated more than once in the URL.
This function performance is better than the one I posted before (delete_value_from_url).
function RemoveArgFromURL($URL,$Arg)
{
while($Pos = strpos($URL,"$Arg="))
{
if ($Pos)
{
if ($URL[$Pos-1] == "&")
{
$Pos--;
}
$nMax = strlen($URL);
$nEndPos = strpos($URL,"&",$Pos+1);
if ($nEndPos === false)
{
$URL = substr($URL,0,$Pos);
}
else
{
$URL = str_replace(substr($URL,$Pos,$nEndPos-$Pos),'',$URL);
}
}
}
return $URL;
}

An alternative and more straightforward to the remove an argument from a URL code above is below. I'm not saying its any better than the one above, but its easier to read ;) :p
----------------
function RemoveArgFromURL($URL,$Arg)
{
$Pos = strpos($URL,"$Arg=");
if ($Pos)
{
if ($URL[$Pos-1] == "&")
{
// If Pos-1 is pointing to a '&' knock Pos back 1 so its removed.
$Pos--;
}
$nMax = strlen($URL);
$nEndPos = strpos($URL,"&",$Pos+1);
if ($nEndPos === false)
{
// $Arg is on the end of the URL
$URL = substr($URL,0,$Pos);
}
else
{
// $Arg is in the URL
$URL = str_replace(substr($URL,$Pos,$nEndPos-$Pos),'',$URL);
}
}
return $URL;
}

Hi.
If you ever need to call a php script itself with modified parameters in the query, it may be useful this piece of code.
Just imagine you write a "viewer" with 1000 results and you want to show "page=1" then provide links to "page=2", "page=3" and so on. If you request the URL and simply append the page at the end, you might result in duplicated values in the URI, like "table=customers&page=1&page=2".
I use the modifies version of cox gluer, posted by anonimous an dmodified it a little bit:
// The next function takes a query like "page=2" or "page=2&name=xavi" and uses it to override the self parameters
function everything_self_uri( $new_query )
{
global $REQUEST_URI; // Get the current URI used for the script
$parsed=parse_url( $REQUEST_URI ); // Split into parts
if( isset($parsed['scheme']) ) // Begin to rebuild it
{
$sep = (strtolower($parsed['scheme']) == 'mailto' ? ':' : '://');
$uri = $parsed['scheme'] . $sep;
}
else
{
$uri = '';
}
if( isset($parsed['pass']) ) // Continue to rebuild it.
{
$uri .= "$parsed[user]:$parsed[pass]@";
}
elseif( isset($parsed['user']) )
{
$uri .= "$parsed[user]@";
}
if ( isset( $parsed['host'] ) ) { $uri .= $parsed['host']; } // Continue to rebuild it.
if ( isset( $parsed['port'] ) ) { $uri .= ":$parsed[port]"; } // Continue to rebuild it.
if ( isset( $parsed['path'] ) ) { $uri .= $parsed['path']; } // Continue to rebuild it.
if ( isset( $parsed['query'] ) ) { $uri .= "?" . everything_mix_query( $parsed[query], $new_query ); } // Continue to rebuild it.
if ( isset( $parsed['fragment'] ) ) { $uri .= "#$parsed[fragment]"; } // End to rebuild it.
return $uri;
}
// The next function is the mixer itself
function everything_mix_query( $old_query, $new_query )
{
// This function takes two queries and returns one single query.
// The queries are for URLs. An example of query is: "name=michael&destination=London"
// This function puts all the params of every query and if one param is repeated in the first and the second, the "new_query" remains, while
// the "old_query" looses its value.
$old_query_array = explode( "&", $old_query );
$new_query_array = explode( "&", $new_query );
$result_query_array = array(); // Empty a new array
$old_count = count( $old_query_array ); // Count the old parameters
for( $i = 0; $i < $old_count; $i++ ) // Add the old parameters
{
$current_item = $old_query_array[ $i ]; // Ex: Current item = "name=xavi"
$pair = explode( "=", $current_item ); // Ex: Pair = {"name", "xavi"}
$key = $pair[ 0 ]; // Ex: Key = "name"
$result_query_array[ $key ] = $old_query_array[ $i ]; // Ex: $result[ "name" ] = "name=xavi"
}
$new_count = count( $new_query_array ); // Count the new parameters
for( $i = 0; $i < $new_count; $i++ ) // Add the new parameters
{
$current_item = $new_query_array[ $i ]; // Ex: Current item = "name=smith"
$pair = explode( "=", $current_item ); // Ex: Pair = {"name", "smith"}
$key = $pair[ 0 ]; // Ex: Key = "name"
$result_query_array[ $key ] = $new_query_array[ $i ]; // Ex: $result[ "name" ] = "name=smith"
}
$result_query = implode( "&", $result_query_array );
return $result_query;
}
// You can now call the whole thing like this:
$URI = everything_self_uri( "page=3" );
echo( '<a href="' . $URI . '">Click here</a>' );
Hope to help. If you can copy/paste this code, I'm then happy ;-)
See you.

If you would ever need to rebuild a URL when all you have is the path (saved in a db in my case), or to provide an index link back to the main http://www.whatever.com but you don't always know if your URL will be the same, then you can use this:
$url = parse_url($PHP_SELF);
$host = str_replace($url[path],"",$PHP_SELF);
print($host);
That will remove anything after the .com, .net, .org, or what ever the TDL is.

Just a note but this tripped me up in a quick cut and paste of the code.
If you use this function on something that is a valid host name already then in the [url] element is nothing.

Perhaps someday you need to modify somefield from the parse_url() and then build the url again with this data.
To make it, here I post the "glue_url" function:
// param $url is the result array from the parse_url()
function glue_url ($url){
if (!is_array($url)){
return false;
}
// scheme
$uri = (!empty($url['scheme'])) ? $url['scheme'].'://' : '';
// user & pass
if (!empty($url['user'])){
$uri .= $url['user'].':'.$url['pass'].'@';
}
// host
$uri .= $url['host'];
// port
$port = (!empty($url['port'])) ? ':'.$url['port'] : '';
$uri .= $port;
// path
$uri .= $url['path'];
// fragment or query
if (isset($url['fragment'])){
$uri .= '#'.$url['fragment'];
} elseif (isset($url['query'])){
$uri .= '?'.$url['query'];
}
return $uri;
}
