Rename image file on upload php

I have a form for uploading image. The index.html submits data to resizer.php. The coding is as follows;

index.html

<form action="resizer.php" method="post" enctype="multipart/form-data">
    Image: <input type="file" name="file" />
    <input type="submit" name="submit" value="upload" />
</form>

resizer.php

<?php
require_once('imageresizer.class.php');
$imagename = "myimagename";

//Path To Upload Directory
$dirpath = "uploaded/";

//MAX WIDTH AND HEIGHT OF IMAGE
$max_height = 100;
$max_width = 100;

//Create Image Control Object - Parameters(file name, file tmp name, file type, directory path)
$resizer = new ImageResizer($_FILES['file']['name'],$_FILES['file']['tmp_name'],$dirpath);

//RESIZE IMAGE - Parameteres(max height, max width)
$resizer->resizeImage($max_height,$max_width);

//Display Image
$resizer->showResizedImage();


?>

imageresizer.class.php

<?php

    class ImageResizer{
        public $file_name;
        public $tmp_name;

Everything is working well.. The file get uploaded in it's original filename. But I want to rename the file to "myimagename", which is a variable in resizer.php. How can i make this possible??

Thanks in advance... :)

Try this:

    public function moveImage(){
        global $imagename;
        if(!is_dir($this->dir_path)){
            mkdir($this->dir_path,0777,true);
        }
        if(move_uploaded_file($this->tmp_name,$this->dir_path.$imagename)){
            $fileParts = explode('.', $this->tmp_name);
            $this->setFileName($this->dir_path.$imagename.'.'.$fileParts[count($fileParts)-1]);
        }

    }

Edit: Added the extension for you ;-)

//Create Image Control Object - Parameters(file name, file tmp name, file type, directory path)
$resizer = new ImageResizer($_FILES['file']['name'],$_FILES['file']['tmp_name'],$dirpath);

// Rename
$resizer->setFileName('new_file_name.jpg');

//RESIZE IMAGE - Parameteres(max height, max width)
$resizer->resizeImage($max_height,$max_width);
