title: Separate street name from street number
body: <p>I am trying to separate street names from street numbers which have these patterns:</p>
  
  <ol>
  <li>"street 12"  --- name:street , number:12</li>
  <li>"street12"   --- name:street , number:12</li>
  <li>"street 12a" --- name:street ,  number:12a</li>
  <li>"street12a"  --- name:street , number:12a</li>
  </ol>
  
  <p>What is the regex to get the street name, and the regex to get the street number in php and python?</p>
  
  <p>Note: The number is always after the street name so I guess that should shorten it.</p>
  
  <p>Thanks.</p>
