Undefined Offset / Read Error!

[neridaj]

Hello,

I'm trying to figure out how to get rid of these errors:

Notice: Undefined offset: 1 in output_fns.php on line 315

Notice: getimagesize() [function.getima gesize]: Read error! in
output_fns.php on line 315

function get_imgdim()
{
$dir = get_imgdir();
$files = scandir($dir);
foreach($files as $value) {
// check for image files
if(valid_image_ file($value)) {
// build image array
$imgarr[] = $value;
$dimarr = array();
$count = count($files);
for($i = 0; $i < $count; $i++) {
$size = getimagesize($d ir . $imgarr[$i]); // line 315
list($width, $height) = $size;
$dimarr[$imgarr[$i]] = array("width" =$width, "height" =>
$height);
}
}
}
return $dimarr;
}

Thanks for any help,

Jason

Hi,

That means that $imgarr[$i] isn't defined.
To debug: add before that line:
echo "<pre>";
print_r($imgarr );
echo "</pre>";
exit;

I forgot my regards. ;-)
