title: Retrieving 12345 from the string "wawawa #99999 hahaha # lalala #12345,no wonder"
body: <p>Does anyone know how to retrieve "12345" from the string:</p>
  
  <blockquote>
    <p>"wawawa #99999 hahaha # lalala #12345,no wonder"</p>
  </blockquote>
  
  <p>I tried the pattern <code>\#(.*?)</code>, no wonder\, but these returns from #99999 on-wards. I need to start grabbing from the last <code>'#'</code> character on-wards.</p>
  
  <p>Thanks.</p>
