title: call_user_func with dynamic parameters
body: <p>I am using php 5.3 (Windows 7).</p>
  
  <p>I create a function that call another function with dynamic variables</p>
  
  <pre><code>func A call func B.
  func2($a, $b, $c, ) ... the number of parameters can be dynamic.
  </code></pre>
  
  <p>call_user_func("func2", $x) - what is the correct syntax to use : call_user function with parameters, that the number of parameters is unknown.</p>
  
  <p>Thanks :)</p>
