title: Mobile Phone Validation - Php
body: <p>Apologies to bother you with a question that may seem quite blunt to some of you but I was wondering if any of you could shed some light on the validation side of things</p>
  
  <p>Ive got a text field and I need validation on a mobile number so i need to validate that it has +44 at the beginning and including the +44 that it is 13 digits long , I found a few different techniques but nothing that defined it step by step only just copy and paste , Id like to learn how to do it so I know for future reference.</p>
  
  <p>Any help would be appreciated</p>
  
  <p>Thanks</p>
