title: Are "elseif" and "else if" completely synonymous?
body: <p>Are <code>elseif</code> and <code>else if</code> completely synonymous, or is there a difference?</p>
  
  <p>Does Zend have an accepted "standard" on which one to use?</p>
  
  <p>While I personally dislike seeing <code>elseif</code> in the code, I just need to know if they're synonymous and the PHP manual isn't the easiest to search.</p>
