答
preg_match('/^[\s\pL'-]+$/',$string)
This is the way I'd do it
//EDIT
Maybe if you have a minimum count of letters, use this:
preg_match("/^[\s\pL'-]{5,}$/",$string) //{x,} ---> x is your min number
答
Try /^[a-zA-Z'\-\s]*$/ as your regex string. Note that this regex will also match blank strings.
