FTP Login PHP Script from Website

Hi. I am looking to create a FTP login from my website.
It will have two fields, a username and pass.

My server/host connects from a broswer with 'ftp://specificuser@website.com' and locks the users into their directories.

The whole 'Username' would be 'specificuser@website.com'. That's fine.

1) The first problem is with the PHP script I found, I would have to to connect to a generic FTP address instead and this is not possible with the above scenario. I don't know how to modify the PHP code below.

2) Second problem. I'd like to take out the directory portion of the HTML. It's simple to remove but how does it relate to the PHP portion?

Can someone be kind enough to take a look at it?

Here is the HTML code referencing the ftp.php file:

<form action="ftp.php/" method="POST">
<p>Username<input name="username">
<p>Password<input name="password" type="password">
<p><input name="login" type="submit" value="login">
</form>

<?php

/*
*/

// quick "die" function
function funk_die($msg) {
    if($msg=='normal') {
return "<html><body><a href=\"ftp.php\">back</a></body></html>";
    }
}

// function to give dir listing stuff
function dir_funk () {

// cookie?
global $ftp;

// dir name
$dir=ftp_pwd($ftp);
// dir listing array
$dirlist=ftp_rawlist($ftp,$dir);

// print the directory listing
$funk = "<html><body><p>current directory: <b> $dir </b></p>";
$funk .= "<p><a href=\"ftp.php?&updir=$dir\">go up one level</a>
</p>";

$funk .= "<p>
<table cellspacing=0 cellpadding=2 border=1>

    while(list($i,$thingy)=each($dirlist)) {

$thingy=preg_replace("/\s+/", " ", $thingy);

if($i==0) {
echo "";
} else {
list($chmod,$thing,$owner,$group,$size,$month,$day,$time,$filename)=explode(" ",$thingy);
    if(ereg("d",$chmod)) {
$funk .= "<tr><td>$chmod</td><td><a href=\"ftp.php?dir=$dir/$filename\">$filename</a></td>

?>

Could someone show me proper working code please?
