How to sort string array when it contains int values

$files = array (
  '/test/tmp/file_7.sql.gz',
  '/test/tmp/file_9.sql.gz',
  '/test/tmp/file_11.sql.gz',
  '/test/tmp/file_1.sql.gz',
  '/test/tmp/file_3.sql.gz',
  '/test/tmp/file_12.sql.gz',
  '/test/tmp/file_13.sql.gz',
  '/test/tmp/file_10.sql.gz',
  '/test/tmp/file_5.sql.gz',
  '/test/tmp/file_2.sql.gz',
  '/test/tmp/file_8.sql',
  '/test/tmp/file_4.sql.gz',
  '/test/tmp/file_6.sql.gz',
);

echo "<pre>";
sort($files);
print_r($files);

When use sort() it gives output like following

Array
(
    [0] => /test/tmp/file_1.sql.gz
    [1] => /test/tmp/file_10.sql.gz
    [2] => /test/tmp/file_11.sql.gz
    [3] => /test/tmp/file_12.sql.gz
    [4] => /test/tmp/file_13.sql.gz
    [5] => /test/tmp/file_2.sql.gz
    [6] => /test/tmp/file_3.sql.gz
    [7] => /test/tmp/file_4.sql.gz
    [8] => /test/tmp/file_5.sql.gz
    [9] => /test/tmp/file_6.sql.gz
    [10] => /test/tmp/file_7.sql.gz
    [11] => /test/tmp/file_8.sql
    [12] => /test/tmp/file_9.sql.gz
)

But I want it like this

Array
(
    [0] => /test/tmp/file_1.sql.gz
    [1] => /test/tmp/file_2.sql.gz
    [2] => /test/tmp/file_3.sql.gz
    [3] => /test/tmp/file_4.sql.gz
    [4] => /test/tmp/file_5.sql.gz
    [5] => /test/tmp/file_6.sql.gz
    [6] => /test/tmp/file_7.sql.gz
    [7] => /test/tmp/file_8.sql
    [8] => /test/tmp/file_9.sql.gz
    [9] => /test/tmp/file_10.sql.gz
    [10] => /test/tmp/file_11.sql.gz
    [11] => /test/tmp/file_12.sql.gz
    [12] => /test/tmp/file_13.sql.gz
)

You can use natsort() with array_values()

echo "<pre>";
natsort($files);
$files= array_values($files);
print_r($files);
echo "</pre>";

You have to use a natural order algorithm : natsort() :

natsort($files);

And use array_values() to reset the index. For example: 

natsort($files);
$files = array_values($files);
echo "<pre>";
print_r($files);
