function not working

[freebie]

Hi,
I was wondering if anyone could please explain why the following doesn't work.
<?php
$ImageURLs=array();
$ImageURLs[0]="something.gif";
$ImageURLs[1]="some.jpg";
function getImageName($number){
return $ImageURLs[$number];
}
echo getImageName(0);
echo getImageName(1);
?>

The doesn't display anything, but I would think that it would
Thanks for any suggestions.

The image array isn't in function scope.

This should work.

<?php
$ImageURLs=array();
$ImageURLs[0]="something.gif";
$ImageURLs[1]="some.jpg";

function getImageName($number, $img_arr){
    return $img_arr[$number];
}
echo getImageName(0, $ImageURLs);
echo getImageName(1, $ImageURLs);
?>

Because ImageURLs is a global variable and your function does not know about it. Try:

function getImageName($number)
{
global $ImageURLs;
return $ImageURLs[$number];
}

Thanks guys.
I thought it might have been a scope problem but I didn't know what to do.

Thanks for the help
