A:
You should use the $_FILES superglobal and move_uploaded_file() function to see which files were uploaded successfully and move them to their final location in case they were.
The $_POST superglobal will contain the submitted username and password.

A:
first off check out these pages on PHP.net
But to get you started here's a couple stub files.
uploadForm.html
<html>
<body>
<form action="processStuff.php" enctype="multipart/form-data" method="POST">
username: <input type="text" name="username" />
password: <input type="password" name="password" />
<p>
<input type="file" name="uploadFile[]" /><br />
<input type="file" name="uploadFile[]" /><br />
<input type="file" name="uploadFile[]" /><br />
<!-- Add as many of these as you want -->
</p>
<p>
<input type="submit" />
</p>
</form>
</body>
</html>
processStuff.php
<pre>
<?php
echo '<h2>Username & password</h2>'
echo "Username: {$_POST['username']}\nPassword: {$_POST['password']}";
echo '<hr />';
echo '<h2>Uploaded files</h2>'
foreach($_FILES['uploadFile']['tmp_name'] as $i => $tempUploadPath) {
if (empty($tempUploadPath)) {
// this <input type="file" /> was "blank"... no file selected
} else {
// a file was uploaded
echo '<strong>A file named "', $_FILES['uploadFile']['name'][$i], "\" was uploaded</strong>\n";
echo "\ttemporarily stored at: ", $tempUploadPath, "\n";
echo "\tmime type: ", $_FILES['uploadFile']['type'][$i], "\n";
echo "\tsize: ", $_FILES['uploadFile']['size'][$i], " bytes\n";
echo "\terror code",
((empty($_FILES['uploadFile']['size'][$i])
? '<em>no errror</em>'
: $_FILES['uploadFile']['size'][$i])),
"\n\n";
// do something useful with the uploaded file
// access it via $tempUploadPath and use move_uploaded_file() to move
// it out of the temp path before you manipulate it in any way!!!!!
// see http://us3.php.net/features.file-upload
// and http://us3.php.net/manual/en/function.move-uploaded-file.php
}
}
?>
</pre>
The HTML file shows how to set the enctype of the <form> & the second form show you how to access the submitted username & password & finally how to loop thru every uploaded file.
As noted you MUST move the file(s) ASAP. They're uploaded to a temp location and the system will delete them unless you deal with them. So move 'em somewhere first then do whatever you need w/ them.
Hoep this helps

I think pointing the questioner to a Tizag.com link is quite appropriate here. Gave me a chuckle, actually. Perfect level of complexity for them.
