title: PHP function scope
body: <p>I know this is kind of a hacky thing I'm trying here, but I'm wondering if this is even possible. is there anyway I can access the <code>$x</code> variable in the following code, without passing arguments?</p>
  
  <pre><code>function foo() {
   $x = 1;
   return bar();
  }
  
  function bar() {
    //get $x from foo here somehow?
    return $x ? 'stuff' : 'other stuff';
  }
  </code></pre>
