  'http://exmpale.com/abc/exmpale2.html');

but it took all result, please help me thanks you.

I suggest you take a look at loops and substring functions. Start looking into the documentation, start using google for that. Then start your own script, try to solve this yourself. Then, if you run into a specific issue with your own code, then is the time to ask here and post your code inside the question. We are not here to do your work for you. We are here to help you with getting your work done. — arkascha

Simply use the php function preg_match_all and the matched string will get loaded in an array that you supply to the above function as an argument. Please read the PHP manual on preg_match_all and create a regex for your needs. You can test your regex here

Since you dont provide what kind of data structure the urls are stored in, I assume it's a raw string:

$data_raw = "http://exmpale.com/abc/exmpale.html
http://exmpale.com/abc/exmpale1.html
http://exmpale.com/abc/exmpale2.html
http://exmpale.com/abc/exmpale/exmpale1.html
http://exmpale.com/abc/exmpale/exmpale2.html
http://exmpale.com/abc/exmpale/exmpale3.html
http://exmpale.com/abcd/exmpale1.html
http://exmpale.com/abcd/exmpale2.html
http://exmpale.com/abcd/exmpale2.html
http://exmpale.com/abcd/exmpale4.html
http://exmpale.com/abc/abc/exmpale1.html
http://exmpale.com/abc/abc/exmpale2.html
http://exmpale.com/abc/abc/exmpale3.html
http://exmpale.com/abc/abc/exmpale4.html
http://exmpale.com/abc/abc/exmpale5.html";

$urls = explode("\n", $data_raw);

$accept_host = "exmpale.com";
$accept_path = "/abc/";

$filtered_urls = array_filter($urls, function($url) use($accept_host, $accept_path) {
    $parts = parse_url($url);   
    return $parts['host'] == $accept_host
        && strpos($parts['path'], $accept_path) === 0
        && strpos($parts['path'], '/', strlen($accept_path)) === false;
});

printf("<pre>%s</pre>", print_r($filtered_urls, true));

Yields:

Array
(
    [0] => http://exmpale.com/abc/exmpale.html
    [1] => http://exmpale.com/abc/exmpale1.html
    [2] => http://exmpale.com/abc/exmpale2.html
)

I understand that you want each url seperated by a comma. Have a look at the update.

I just saw your update. The result you are asking for is the array $filtered_urls. Have you tried the code?

@phuochq Ok, so you will not accept any additional path parameters after /abc/?
