Phone request validation

I have used the following Phone Number package in the past - it worked well:

Request validation + regex solution:

'telephone' => 'required|regex:/\+421[0-9]{10}/'

This may be useful for frontend formatting: https://bashooka.com/coding/javascript-libraries-for-dealing-with-phone-numbers/

The number you provided +421915490545 is formed by +421 then 9 numbers 915490545 instead of 10.

But a regex to validate the rule (+421 then 10 numbers) could be something like:

'phone' => 'required|regex:/\+421\d{10}/'

in your validation array

@johny-22 The best way is to send the phone number to a service like Twilio for validation, who will then return the phone number in both the E.164 format, as well as the “local” formatted version.

Don’t try and write a regular expression yourself because there are a multitude of ways a user can input a phone number and I can guarantee your regular expression won’t match all of them.

Thank you all for your advice. In the end I decided to use https://github.com/Propaganistas/Laravel-Phone as recommended @tykus we'll see how it works live. Well thank you
