title: simple PHP function call is no longer working
body: <pre><code>class blah{
  
      function a( x ){
      $variablename = b();
      ....
      }
  
      function b(){
      echo("why is this code (first line of function b) seemingly unreachable");
      ....
      }
  }
  </code></pre>
  
  <p>it works fine when executed on a local server but not otherwise!?</p>
