单击链接时将URL变量传递给php

Question

I have URL in this from: locahhost/index1.php?option=com_lsh&view=lsh&event_id=xxxxx&tv_id=xxx&tid=xxxx&channel=x

when the user click this link, the file index1.php should process this the URL then produce

new URL in this form localhost/static/popups/xxxxxxxxxxx.html wher xxxxxxxxxxxxx is the

event_id, tv_id, tid and chanel.

to do this I am using parse url function in the file index1.php as following :

<?php
$url = 'http://localhost/index1.php?option=com_lsh&view=lsh&event_id=&tv_id=&tid=&channel=';
$parsed = parse_url( $url );
parse_str( $parsed['query'], $data );
$newurl = 'http://localhost.eu/static/popups/'.$data['event_id'].$data['tv_id'].$data['tid'].$data['channel'].'.html';
header("Location: $newurl");
?>

but its not working i think this is due to something wrong in $url = 'http://localhost/index1.php?option=com_lsh&view=lsh&event_id=&tv_id=&tid=&channel=';

what is wrong with this? also i want it when for example tv_id not present in the url it put instead 0 in the newurl

$url = 'http://localhost/index1.php?option=com_lsh&view=lsh&event_id=&tv_id=&tid=&channel=';
$parsed = parse_url( $url );
parse_str( $parsed['query'], $data );

$keys = array('event_id', 'tv_id', 'tid', 'channel'); // order does matter
$newurl = 'http://localhost.eu/static/popups/';
foreach ($keys as $key)
    $newurl.= empty($data[$key])?0:$data[$key];

$newurl.='.html';

echo $newurl;

returns:

http://localhost.eu/static/popups/0000.html

UPDATE: You do not need to make an $url variable and parse it into an array of values. When user clicks a link data comes with GET method. If you use GET or POST instead of $url, just use $_REQUEST['variable'] (or $_GET[''] or $_POST[''])

$keys = array('event_id', 'tv_id', 'tid', 'channel'); // order does matter
$newurl = 'http://localhost.eu/static/popups/';
foreach ($keys as $key)
    $newurl.= empty($_REQUEST[$key])?0:$_REQUEST[$key];

$newurl.='.html';

echo $newurl;
