title: Regex for French telephone numbers
body: <p>I'm trying to implement a Regex that allows me to check if a number is a valid French telephone number.</p>
  
  <p>It must be like this:</p>
  
  <pre><code>0X XX XX XX XX
  </code></pre>
  
  <p>or:</p>
  
  <pre><code>+33 X XX XX XX XX
  </code></pre>
  
  <p>Here is what I implemented but it's wrong ...</p>
  
  <pre><code>/^(\+33\s[1-9]{8})|(0[1-9]\s{8})$/
  </code></pre>
