title: php explode all characters
body: <p>I'm looking for the equivalent of what in js would be <code>'this is a string'.split('')</code> for PHP.</p>
  
  <p>If I try <code>$array = explode('', 'testing');</code> I get an error <code>Warning: explode() [function.explode]: Empty delimiter in</code></p>
  
  <p>Is there another way to do this?</p>
