str_word_count

Подсчитывает количество слов, входящих в строку string . Если необязательный аргумент format не передан, возвращается целое число, равное количеству слов. В случае, если указан аргумент format , возвращается массив, содержимое которого зависит от значения format . Ниже описаны допустимые значения аргумента format и соответствующие им возвращаемые значения.

Для этой функции «слово» обозначает строку с алфавитными символами, зависящую от локали, которая также может содержать символы «‘» и «-«, но не может начинаться с них.

Список параметров

• 0 — возвращает количество найденных слов
• 1 — возвращается массив, содержащий все слова, входящие в строку string
• 2 — возвращается массив, индексами которого являются позиции в строке string , а значениями — соответствующие слова.

Список дополнительных символов, которые будут рассматриваться как «слово»
