title: call all functions that have prefix
body: <p>Is it possible in PHP to call all functions that have a certain prefix ?</p>
  
  <p>for example i have 70 functions 
  most start with </p>
  
  <blockquote>
    <p><em>func1</em>.... <em>func2</em> ....</p>
  </blockquote>
  
  <p>i want to call all functions that start with <code>_func1</code>
  is there any PHP function for that ? something like call_user_func but instead of a callback name to pass it something like <code>'_func1*'</code></p>
  
  <p>i know i can do it with 'get_defined_functions' but wonder if there's already such a function.</p>
