first file from every subfolder!

How do I get a list of the first file of every subfolder?
This is what i have so far
<?php
function getfirstImage($dirname)
{
global $imageName;
$ext = array("jpg", "png", "jpeg", "gif", "JPG", "PNG", "GIF",
"JPEG");
if($handle = opendir($dirname))
{
while(false!== ($file = readdir($handle)))
{
if(strstr($file, "." . $ext[$i])!= '.' && strstr($file, "." .
$ext[$i])!= '..')
{
break;
}
}
$imageName = $file;
closedir($handle);
}
return($imageName);
}

echo getfirstImage('../galleri/galleri/diverse/');
?>

$getfirstImage(../galleri/galleri/)

determines whether the file is a directory (is_dir) and call
getfirstImage() for each directory.

function getfirstImage($dirname)
{
$imageName = false;
$ext = array("jpg", "png", "jpeg", "gif", "JPG", "PNG", "GIF",
"JPEG");
if($handle = opendir($dirname))
{
while(false !== ($file = readdir($handle)))
{
$lastdot = strrpos($file, '.');
$extension = substr($file, $lastdot + 1);
if ($file[0] != '.' && in_array($extension,
$ext))
{
break;
}
}

$imageName = $file;
closedir($handle);

}
return($imageName);
}

Why aren't you just doing
if ($file != '.' && $file != '..')
if those are the two you want to bypass. If you THEN want to check that
it is one of your extension types, then do a foreach on $ext.
