Answer 1

I don't know the rules/conditions you need but this is a way:
$url = parse_url('http://localhost/cms/uploads/files/1/images/hd-wallpaper-40.jpg');
echo str_replace('/cms/uploads/files/', '', $url['path']);
UPDATE:
If imagesis static:
$url = parse_url('http://localhost/cms/uploads/files/1/images/hd-wallpaper-40.jpg');
preg_match('/[0-99999]\/.*/', $url['path'], $matches);
echo $matches[0];

Answer 2

You can use parse_url function to get whatevers after the host (in this case localhost) and then explode the path, slice an array and implode it back:
$str = "http://localhost/cms/uploads/files/1/images/hd-wallpaper-40.jpg";
$parsed_url = parse_url($str);
echo implode("/", array_slice(explode("/", $parsed_url['path']),4));

Answer 3

a simple solution may be;
$basepath = 'http://localhost/cms/uploads/files/';
$url = 'http://localhost/cms/uploads/files/1/images/hd-wallpaper-40.jpg';
if (strncmp($basepath, $url, strlen($basepath)) == 0 ) {
$result = substr($url, strlen($basepath));
} else {
$result = false;
}
echo $result;

Try this, dynamic content with '/1/' will work perfectly
$str = "http://localhost/cms/uploads/files/1/images/1/hd-wallpaper-40.jpg";
//url as string
$pos = strpos($str,'1'); //position of first '1' in url
$len = strlen($str); //length of url string
$str1 = substr($str,$pos,($len-$pos)); //substring from '1' onwards
There are few drawbacks too. If the '1' occurres before , i mean url = "http://localhost/cms1/uploads/files/1/images, it will give wrong result.
If you use dynamic author id, instead of 1, save author id as a variable and insert in strpos(). The below one will be more accurate and you can use dynamic authorID too.
$str = "http://localhost/cms/uploads/files/1/images/1/hd-wallpaper-40.jpg";
//url as string
$authid = 1; //author id
$searchstring = '/'.$authid.'/'; // create a search string '/1/'
$pos = strpos($str,$searchstring); //position of first '/1/' in url
$len = strlen($str); //length of url string
$str1 = substr($str,$pos+1,($len-$pos)); //substring from '1' onwards
