title: PHP: Get thousand from number
body: <p>When the user enters a number from 1000 and above I want to be able to get the thousand for that number in an array.</p>
  
  <p>For example…</p>
  
  <p>Number entered by user: 165124</p>
  
  <p>My array should return:</p>
  
  <pre><code>array('thousand_low' =&gt; 165000, 'thousand_high' = 165999)
  </code></pre>
  
  <p>Thanks!</p>
