pass variable into function and retaining value

I have a function that displays the footer on the web pages that uses an image reference. To reference the location of the directory I have created a variable called $image_path that holds the directory location of the images. My code looks like this:

Code:

$image_path="http://127.0.0.1/testsite/images";

function footer()
{
   global $image_path;
   echo "<img src=\"$image_path/footer.gif\" alt=\"#\" name=\"footerImage\" width=\"11\" height=\"14\" border=\"0\" id=\"footerImage\">";
}

I several different footers for different sections of the website.
When I come to call the function it displays it without any problem, but I get the error message:

Fatal error: Cannot redeclare footer() (previously declared in C:\Progra~1\Apache Group\Apache2\htdocs\testsite\includes\common\inc_ common.php:11) in C:\Progra~1\Apache Group\Apache2\htdocs\testsite\includes\common\inc_ common.php on line 9

I have had a look through the PHP books and it looks like that I am doing the right thing in calling the variable and declaring it as global within the function.

Am I doing it wrong?

Thanks.

Michael.

problem solved!!!

I was recalling the include file again at the bottom of the web page thats why it was saying there was a redeclare.

silly me!

As a matter of interest, why are you using the full URL ("http://127.0.0.1/testsite/images")?

If / is the root directory of your site, and testsite is a subdirectory of it (which is what appears to be happening) then you could point to the images subdirctory via:
<img src="/testsite/images/imagename.png" width... height... etc. />

The leading slash indicates "root of website".

Hi Daniel,

I dont think that I have configured my Apache correctly to do that.

When I put in the / (slash) it goes to the Apache root and I get my perosonal page that I set up.
