Uploading images from FLASH in CakePHP

Question

I'm having trouble handling my images created from my flash application, it sends the data via raw post data, and it's writing the image to my /webroot folder.

Here's the php code I have in an "AvatarController.php" file.

public function uploadImage()
{
    $this->autoRender = false; // no view file

    if ($this->request->is('post')) // if post data
    {
        $aUser = $this->aCurrentUser(); // gets user info

        if ( isset ( $GLOBALS["HTTP_RAW_POST_DATA"] )) // gets raw post data
        {
            $sImgName = $aUser['User']['username'] . '_full' . '.png';

            $fp = fopen($sImgName, "wb");
            fwrite( $fp, $GLOBALS[ 'HTTP_RAW_POST_DATA' ] );
            fclose( $fp );
        }

    }
}

what I'm having trouble with is saving this into a different folder eg /webroot/avatars, and how would I go about resizing the image, ultimately what I want to do is have three or so sizes, so for example "Username_full", "Username_80", "Username_50"; so the full size, 80% smaller, 50% smaller, etc.

I've just never handled uploads like this, from flash.

Any help, suggestions?

This looks like a decent tutorial on the resize/move business PHP. The other part with regard to grabbing the file itself, see this post, http://www.kirupa.com/forum/showthread.php?360502-AS3-PHP-File-Upload what you're doing may work but I just tend to use the $_FILES variable as it's clear to me what's going to be in there.
