            @$file_path = $file_path . basename( $_FILES['photo']['name']);
            if(move_uploaded_file(@$_FILES['photo']['tmp_name'], $file_path)) 
            {
                $response1=array();

                $query = "update alumni set photo = '".$file_name."' where alumni_id = '".$data['alumni_id']."'";
                $query_run=  mysql_query($query);

Is the question, what to do with it after uploading? Since uploading is uploading, whether it's base64 encoded or not? — MrWhite

Recently I've built something like that:

        define("UPLOAD_DIR", "images/signatures/");
        $signature = $_POST['signature']; // THIS IS YOUR BASE64 ENCODED STRING
        $signature = str_replace('data:image/png;base64,', '', $signature);
        $signature = str_replace(' ', '+', $signature);
        $data = base64_decode($signature);
        $file = UPLOAD_DIR . md5(microtime()) . '.png';
        $success = file_put_contents($file, $data);
