Validating phone number php

Rated 4.94/5 based on 935 customer reviews

Let's say you have a string representing a phone number from Switzerland.This is how you parse/normalize it into a Phone Number object: This library uses phone number metadata from Google's libphonenumber.The validating phone number is an important point while validating an HTML form.In this page we have discussed how to validate a phone number (in different format) using Java Script : At first, we validate a phone number of 10 digits with no comma, no spaces, no punctuation and there will be no sign in front the number. Ergo: Validation is culture dependend and not quite as simple as you this an Australian phone number, a UK number, an international number, etc, etc? Depending on the country, digit groups get distanced with spaces, dots or dashes.I have created a script that will strip out all characters in a string except numerical digits.This not only creates a standardized string that can be later used in a comparison or stored in a database, but also ensures that the data that is received on the server end contains only the expected data.

There could be additional releases where needed to fix critical issues that can not wait until the next release from Google.

The problem with validating user input on the client side is that there is no security.

Validating phone numbers from around the world can open up more worms than email validation - and I don't think I've ever seen that done 100% infallible.

At this point I'm assuming the user wants my content so the numbers themselves are trusted.

I'm using in an app that ultimately sends an SMS message so I just want the raw numbers no matter what.
