Drawing saving retreving data

[zooray]

Hi all
I am looking for a tutorial on: Drawing saving retreving data.

I have done a small drawing canvas and now would like to save to DB (php/mysql) and retrieve back the drawing cordinates....how to?

//=========== drawing ==============================
drawHolder.onMouseDown = function() {
    if (1) {
        //Mouse.show();
        //Airbrush._visible = true;
        _root.Airbrush.gotoAndStop(1);
        //this.lineStyle(my_nstep.value, cmp1.ColorValue, 100, true, "normal", "round", "round", 4);
        this.lineStyle(my_nstep.value, cmp1.ColorValue, 100, true, "none", "round", "miter", 1);
        //100, true, "none", "round", "miter", 1);
        this.moveTo(_xmouse, _ymouse);
        this.onMouseMove = function() {
            this.lineTo(_xmouse, _ymouse);
            updateAfterEvent();
        };
        this.onMouseUp = function() {
            //_root.Airbrush.gotoAndStop(2);
            delete this.onMouseMove;
        };
    }
}; 

thanks
