  Modified files:              
    /phpdoc/en/reference/strings/functions	strpos.xml 
  Log:
  There was a lot of confusion in the user notes about the !== operator.  An 
  example was added using the !== operator in hopes of clearing some of it up.
  
  Each example now has its own example box and title as well.
