StringTokenizer.php (GPL)

I was porting some of my Java software over to PHP, and I noticed that PHP is still using the old C-style strtok function. It's a pain to use, because it's impossible to interleave two or more strtok's. So I decided to port Java's beautiful StringTokenizer over to PHP. The attached file is the result of this port. It supports most of the basic functionalities.

StringTokenizer class, when instantiated witha a string, breaks the string up into tokens separated by any characters specified as delimiters. Unlike the PHP strtok, you can interleave as many StringTokenizer's as you want. Each one operates independently from the others.

Interface

class StringTokenizer
{
  function StringTokenizer ($str, $delim = "\t\r\n")
  function countTokens ()
  function hasMoreTokens ()
  function nextToken ()
}

The default constructor takes a default parameter of white spaces. I noticed that I forgot to add the space character to it. This new version includes the space. Interface for the constructor has been changed to the following.

function StringTokenizer ($str, $delim = " \t\r\n")
