Often see a novice asked PHP there is no similar to the ASP's left function or right function, to intercept a string on the left-hand side or the beginning of the N-character function. Of course the answer is yes. PHP's substr function can do, but PHP to the two functions into one, here again to share a more excellent function of intercepting strings.
