Here is a java like StringTokenizer class using strtok function:
<?php
/**
* The string tokenizer class allows an application to break a string into tokens.
*
* @example The following is one example of the use of the tokenizer. The code:
* <code>
* <?php
* $str = 'this is:@\t\n a test!';
* $delim = ' !@:'\t\n; // remove these chars
* $st = new StringTokenizer($str, $delim);
* while ($st->hasMoreTokens()) {
* echo $st->nextToken() . "\n";
* }
* prints the following output:
* this
* is
* a
* test
* ?>
* </code>
