title: Convert Python code to PHP but keep it "nice, clean and optimized"
body: <p>A friend of mine told me: "look at this code and try to do it in PHP as easy, concise, and clear".</p>
  
  <pre><code>colors = ['red', 'blue', 'green', 'yellow']
  print 'Choose', ', '.join(colors[:-1]), 'or', colors[-1]
  </code></pre>
  
  <p>Is it possible? Do you have any "compact but readable" Php code for this?</p>
  
  <p>(BTW I ask it here because this question doesn't fit codereview, and doesn't fit codegolf).</p>
