title: str_replace with apostrophe
body: <p>I have the following word:</p>
  
  <pre><code>d\'b
  </code></pre>
  
  <p>and when I do the following:</p>
  
  <pre><code>$test = str_replace(array("\\", "'"), "", "d\'b");
  </code></pre>
  
  <p>the outcome is:</p>
  
  <pre><code>d'b
  </code></pre>
  
  <p>Any idea why the apostrophe is not being replaced?</p>
