title: Access variable from scope of another function?
body: <pre><code>&lt;?php
    function foo($one, $two){
      bar($one);
    }
  
    function bar($one){
      echo $one;
      //How do I access $two from the parent function scope?
    }
  ?&gt;
  </code></pre>
  
  <p>If I have the code above, how can I access the variable $two from within bar(), <strong>without</strong> passing it in as a variable (for reasons unknown).</p>
  
  <p>Thanks,</p>
  
  <p>Mike</p>
