Is there a way to read a variable at top which is defined some where at the bottom.
Here is an example of such situation:

```
<!--this image is somewhere on top of the page-->
<img src="/<?php print logoPath(); ?>" border="0" />

// this code is somewhere on bottom of the page
$logo_query = "select logo_path from table where id = $row->user_id";
$res_logo = mysql_query($logo_query) or die(mysql_error());
$row_logo = mysql_fetch_object($res_logo);
$logo_path = $row_logo->logo_path;

function logoPath()
{
    global $logo_path;
    return $logo_path;
}

```

I tried to use that function to return value but even that doesn't seem to work.

Any solution?

Thanks
