I need a regular expression that accept numb开发者_StackOverflow社区ers, spaces and hyphen with a maximum of 8 caracters. Example 2632-632, 3636 252

Thanks

Use this regex:

~^[\d\s-]{0,8}$~

Here is a regular expression that accept numbers, spaces and hyphen with a maximum of 8 caracters.

/^[\d -]{1,8}$/D

The question is, perhaps unknowingly, ambiguous so some liberties have been taken with the details.

"Spaces" is taken to mean the horizontal space character (ASCII 32); a minimum of 1 character is required (empty strings don't match); and contrary to the other answers a trailing newline character will not be accepted (thanks to the D pattern modifier).

/^([0-9 \-]){0,8}$/ ought to work, though I haven't tested so forgive me if I have made a silly error.

---

Try this:

/^(\d|\s|-){0,8}$/

---

Here you go: /^[\d -]{0,8}$/

Edit: Since I was so flippant before, this regex now does exactly what you want: A string with digits (\d), spaces (), and hyphens (-) between 0 and 8 characters long. \s is for "whitespace character", which you didn't specify in the question, thus the change to .

If it must be exactly 8 chars:

/^[\d\s-]{8}$/
