Description:
------------
PHP_compat, str_word_count.php, version 1.7
A bug in numbering keys when the $format = 2
$lastmatch is counted invalid, what may occur to wrong key numbering, if the next word in a string is a substring of previous
Problem fix:

There is

foreach ($word_array as $word) {
$word_assoc[$lastmatch = strpos($string, $word, $lastmatch)] = $word;
}

There should be:
foreach ($word_array as $word) {
$word_assoc[$lastmatch = strpos($string, $word, $lastmatch)] = $word;
$lastmatch+=strlen($word);
}

Hope will be useful
