title: Phone Number Validator/Filter using jQuery or Zend Form?
body: <p>I'm thinking about adding some validation/filtering to the phone number field of my Zend Framework application. Not sure if this is something I should do or not.</p>
  
  <p>I thought it might be helpful for users to have such a feature so I could enforce a particular display format. I'm not sure if the formatting of the phone number should be stored in the database, or when it is retrieved from the database. I don't want to be too strict about this because it's not really that important. I just wanted to prevent half the people from entering <code>123.456.7890</code> as their phone number format and the other half entering <code>(123) 456-7890</code> as the other format. I want the listing of phone numbers to look consistent. So maybe I should use some javascript to help the user enter their number? Maybe there is a jQuery plugin that already does that and I can integrate it with my Zend Form?</p>
  
  <p>What do you think?</p>
