Extract US phone numbers from a string

2018-06-12 05:05:17

I am trying to extract US only phone numbers from a string.

I have looked around the web/SO but have not found any suitable solution for my needs.

To be honest, I have 2.5 years of experience in Web Programming but I suck at RegEX.

Here is only RegEX I wrote (d{3}+-d{3}+-d{4}+)

but it only detects 589-845-2889

Here are phone numbers I want to extract.

589-845-2889

(589)-845-2889

589.845.2889

589 845 2889

5898452889

(589) 845 2889

Please tell me how can I achieve this feat in single Regex for PHP.

EDIT:

If you feel any other format of US number a user can enter, also mention that as well, and include that in RegEX as well.

PS:

Actually I am trying to scrape Craiglist and user may have posted their phone number in any possible format.

In PHP (PCRE) you can use this regex based on conditional subpatterns:

(()?d{3}(?(1)))[-.h]?d{3}[-.h]?d{4}

RegEx Demo

(()? matches optional ( and captures it in group #1

(?(1))) is conditional pattern that matches closing ) only if group #1 is not null ie ( is present on left of the match.

Finally, it works:

^(((d{3}))|(d{3}))[s-.]?d{3}[s-.]?d{4}

tested in notepad++
