title: Divide a string into two in codeigniter
body: <p>I am working in codeigniter, and I want to ask is it possible to divide a string into two
  for example I have 
  <code>$a="hello+man"</code> and I want <code>$b=hello</code> and <code>$c=man,</code> I have searched a lot of functions but they actually delete characters from strings</p>
  
  <p>help</p>
