Matches a regular expression _ regular expression of 5 to 10 digits without repeating numbers

Regular with duplicate 5 to 10 digits can be used with \d{5,10}

No duplicates 5 to 10 digits I thought about it, but I had to check the Internet.

There is a good version, anyway Regexbuddy test passed.

Copy Code code as follows:

^(?! \d*? (\d) \d*?\1) \d{5,10}$

For (?! ......... (......) ... \1) This form I have not studied thoroughly, have the time I really want to study carefully.

Previous example of PHP:

Copy Code code as follows:

<?php
$str = ' 123456789 ';
$search = '/^ (?! \d*? (\d) \d*?\1) \d{5,10}$/';
$result = Preg_match ($search, $STR);

Echo ' matches no repetition of 5 to 10 digits <br/> ';
if ($result >0) {
Echo ' fits ';
}else {
Echo ' does not conform ';
}
?>
