This code is to make a graphical map, which is used in my mmorpg game....

But its not working well with the last code i putted in..

I wanted to make for example all tiles outisde y and x as 20 dirt tiles and all tiles inside 20 grass tiles

well y is working as it should but x is showing everything twice as you see in this picture:

How about this:

 

if ($gridy<20 && $gridx < 20)
{
    echo "<div><td $background width='50' height='50'>$imgsrc</div></td>";
}
else
{
    echo "<div><td $background2 width='50' height='50'>$imgsrc</div></td>";
}

How about this:

 

if ($gridy<20 && $gridx < 20)
{
    echo "<div><td $background width='50' height='50'>$imgsrc</div></td>";
}
else
{
    echo "<div><td $background2 width='50' height='50'>$imgsrc</div></td>";
}

Thanks that helped
