title: PHP: Split string into array, like explode with no delimiter
body: <p>I have a string such as:</p>
  <blockquote>
  <p>&quot;0123456789&quot;</p>
  </blockquote>
  <p>And I need to split <em>each</em> character into an array.</p>
  <p>I, for the hell of it, tried:</p>
  <pre><code>explode('', '123545789');
  </code></pre>
  <p>But it gave me the obvious: <strong>Warning: No delimiter defined in explode)</strong> ..</p>
  <p>How would I come across this? I can't see any method off hand, especially just a function.</p>
