title: How to format an int in format U.S. in European format
body: <p>I get an int in U.S format.</p>
  
  <pre><code>$UsInt = "67,450";
  </code></pre>
  
  <p>I need to convert it in European format.</p>
  
  <pre><code>$EuInt = "67450";
  </code></pre>
  
  <p>I can not use <code>str_replace()</code> to replace the virgule. Do not use <code>str_replace()</code> is a mandatory deposit.</p>
  
  <p>i can't use <code>number_format()</code>, because i can't pass a comma separated number to this function</p>
  
  <p>Would exist a PHP function to do this? Or someone has already had the problem and was able to get out?</p>
