Foreach upload fungerer ikke

Hej alle.

Jeg sidder lige med et problem med en foreach lykke til en imageupload.

Problemet er at den kun vil uploade 1 fil, selvom at der er 3 inputs.

Her er koden:

<form method="post" enctype="multipart/form-data">
<input type="file" name="fil1" ><br />
<input type="file" name="fil2" ><br />
<input type="file" name="fil3" ><br />
<input type="submit" name="filupload" value="Upload" />
</form>

if(billedupload($_FILES))
{
echo "SUCCESS!";
}


function billedupload($_FILES)
{
       
foreach($_FILES as $arrfile){   

$allow_types = array("jpg","gif","png");
                   
$upload_dir = "public/images/test/";
           

if (is_uploaded_file($arrfile["tmp_name"]))
{
$file_ext = strtolower(pathinfo($arrfile["name"], PATHINFO_EXTENSION));
                       
$newname = date('dmyHis').mt_rand().".".$file_ext;
                           
if (in_array($file_ext, $allow_types))
{

if (move_uploaded_file($arrfile["tmp_name"], $upload_dir.$newname))
{
                                   
$image_path = $upload_dir.$newname;
                       
$image_path_new = "public/images/test/thumbs/thumb_".$newname;
                       
$image = open_image($image_path);
                       
$width = imagesx($image);
$height = imagesy($image);
                           
$width_new = 270;
$height_new = $height * ($width_new / $width);
                           
$image_resized = imagecreatetruecolor($width_new, $height_new);
                        imagecopyresampled($image_resized, $image, 0, 0, 0, 0, $width_new, $height_new, $width, $height);
                           
if (!isset($image_resized))
{
$image_resized = $image;
};
                       
                        imagejpeg($image_resized, $image_path_new);
                               
return "SUCCESS!";
                                       
} else {
return false;
};
                   
} else {
return false;
};
           
} else {
return false;
};

};
       
};


Er der nogen der kan se hvad der er galt?
