I'm looking for a regex that will find a dutch phonenumber inside a piece of text. For example:
- Mijn telefoonnnummer is 0612131415
- Mijn telefoonnnummer is 06-12345678
- Mijn telefoonnummer0612131415email
Is shouldn't detect
- 000006121314150000
- -0612131415-
- 00-0612131415-00
This regex (https://regexr.com/3aevr) seems fine for detecting seperate values:
^(( |00(\s|\s?-\s?)?)31(\s|\s?-\s?)?((0)[-\s]?)?|0)1-9((\s|\s?-\s?)?[0-9])((\s|\s?-\s?)?[0-9])\s?[0-9]\s?[0-9]\s?[0-9]\s?[0-9]\s?[0-9]$
Unfortunately it does not work for my purposes. Any help is appreciated.

You can use
(?<![^a-zA-Z\s])((\ |00(\s|\s?-\s?)?)31(\s|\s?-\s?)?(\(0\)[-\s]?)?|0)[1-9]((\s|\s?-\s?)?[0-9])((\s|\s?-\s?)?[0-9])((\s|\s?-\s?)?[0-9])\s?[0-9]\s?[0-9]\s?[0-9]\s?[0-9]\s?[0-9](?![^a-zA-Z\s])
See the regex demo.
The (?<![^a-zA-Z\s]) negative lookbehind makes sure there is an ASCII letter or a whitespace char, or start of string immediately to the left of the current location.
The (?![^a-zA-Z\s]) negative lookahead makes sure there is an ASCII letter or a whitespace char, or end of string immediately to the right of the current location.

You can try with this regex:
(?<![\d\-])\d{2}-?\d{8}(?!\d)
Explanation:
(?<![\d\-]): Negative lookbehind that doesn't matches ...[\d\-]: a digit or a dash (at the beginning of your number)
\d{2}: two digits-?: optional dash\d{8}: eight digits(?!\d): Negative lookahead that doesn't matches ...\d: a digit (at the end of your number)
Try it here.
Note: Lookbehind and lookahead in this regex ensure there are no more than 10 digits in your string (the ones inside the matching pattern).
