I need to get the last 14 characters of a urls relationship inside a .txt

$url = file_get_contents('https://www.site.com.br/relacao.txt');

Within relacao.txt I have:

www.site.com.br/aluno/s/francisco-augusto/11111111111111
www.site.com.br/aluno/s/francisco-fernandes/11111111111112
www.site.com.br/aluno/s/francisco-ocario/11111111111113
www.site.com.br/aluno/s/giselia-augusto/11111111111114
www.site.com.br/aluno/s/giselia-fernandes/11111111111115

Etc.. (várias outras)

And I would like to present it as follows: (only with the last numbers)

11111111111111
11111111111112
11111111111113
11111111111114
11111111111115

Etc...

I've tried it in several ways.

$url = preg_replace("/[^0-9]/", " ", $url);

But the result looks like this:

11111111111111 11111111111112 1111111111113 11111111111114 etc .

I need each number to be on one line.

Can anyone help me?

Edit

As seen, your result is not as written in the question because you are doing the wrong file reading.

Try this:

$arq = file("url.txt");
foreach($arq as $linha){
   echo buscaFinal($linha);
   echo '<br>';
}

function buscaFinal($linha) {
   $var = substr($linha,(strlen($linha)-14),strlen($linha));
   return $var;
}

You can use substr with strlen :

$txt = "www.site.com.br/aluno/s/giselia-augusto/11111111111114";
$var = substr($txt,(strlen($txt)-14),strlen($txt));
echo $var;

Output: 11111111111114

(obs: You have placed 12 characters, but in the example you have 14)

To give the line break, you can use php_eol , echo <br> , echo '\n' , it depends on whether it will print on the file, on the page, etc.

function buscaFinal($linha) {
  $var = substr($linha,(strlen($linha)-14),strlen($linha));
  echo $var;
  echo '<br>';
}

Another way to default the "/" slashes

You can use explode :

$txt = "www.site.com.br/aluno/s/giselia-fernandes/11111111111115";
$var = explode("/", $txt);
echo $var[4];

Output: 11111111111115
