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];

`1` and/or `images` are static? – michelem Aug 30 '15 at 07:05
only `1` is static. `1` is author id and other is dynamic – NewCod3r Aug 30 '15 at 07:07
good work But if author id = `99999+1` your method is good way? – NewCod3r Aug 30 '15 at 07:23
I don't know how many digits you need, you can extend it for example `[0-9]{12}` allows 12 digits to be there – michelem Aug 30 '15 at 07:25
And `preg_match` work in` PHP 5.6 +` ?! or we need add `^` . – NewCod3r Aug 30 '15 at 07:26
Yes `preg_match` exists since PHP 4.x http://php.net/manual/it/function.preg-match.php – michelem Aug 30 '15 at 07:26
`matches[0]` not work in php array see this Q : http://stackoverflow.com/questions/32296447/php-array-filter-send-empty-value – NewCod3r Aug 30 '15 at 12:13

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));

In that case do `implode("/", array_slice(explode("/", $parsed_url['path']),-3));` which will only take the last 3 items in path (1/images/hd-wallpaper-40.jpg) – DannyPhantom Aug 30 '15 at 07:04
only `1` is static. `1` is author id and other is dynamic . `-3` not work n my case – NewCod3r Aug 30 '15 at 07:22
`$matches = array(); preg_match('/\/[0-9]+\/.*$/', $parsed_url['path'], $matches);` after that `$matches[0]` will have what you need – DannyPhantom Aug 30 '15 at 07:27
You can also do `preg_match('/.*(\/[0-9]+\/.*)$/', $parsed_url['path'], $matches);` if there is a chance of having /1/3/4/5 and you need only /5/... Your result will be in `$matches[1]` – DannyPhantom Aug 30 '15 at 07:31

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;

that is why, it is assigned to a variable. Use anything you want as value; like $basepath = $_SERVER['HTTP_HOST]. '/cms/uploads/files/'; – bkilinc Aug 30 '15 at 10:03

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
