title: Stripping "track numbers" from a string
body: <p>I am writing a small music playing web app, and had a problem I couldn't figure out a solution to. Music files often start with a two digit track number, eg:</p>
  
  <p><code>02 Hiding Place (Mudule Remix).m4a</code></p>
  
  <p>or <code>15 An Afternoon on the Moon (Jet Jaguar Remix).m4a</code></p>
  
  <p>How can a PHP script detect the <code>## *</code> rule and remove the numbers and space at the start of the string?</p>
  
  <p>I thought of looping through the first 3 characters and checking if they were numbers and spaces, then removing with <code>substr</code>, is that the best way?</p>
  
  <p>Thanks in advance!</p>
