(no version information, might be only in CVS)

str_word_count -- Return information about words used in a string

## Description

mixed str_word_count ( string string [, int format])

Counts the number of words inside `string`. If the optional `format` is not specified, then the return value will be an integer representing the number of words found. In the event the `format` is specified, the return value will be an array, content of which is dependent on the `format`. The possible value for the `format` and the resultant outputs are listed below.

- 1 - returns an array containing all the words found inside the `string`.

- 2 - returns an associative array, where the key is the numeric position of the word inside the `string` and the value is the actual word itself.

For the purpose of this function, 'word' is defined as a locale dependent string containing alphabetic characters, which also may contain, but not start with "'" and "-" characters.
