Конвертер форматированного текста из mIRC в HTML (IRC2HTML)

PHP, Web, Все рубрики,

PHP-скрипт
Сегодня я написал функцию-конвертер форматированного текста, скопированного из окна (или другого IRC-клиента) в -представление. Назвал функцию ParseIRChat, хотя подходящие названия mIRC2HTML, irc to html и т.д. Функция принимает текст из чата и возвращает HTML-код. Написана на . Открыта как обычно под лицензией BSD.

Версия 1.0.0.0 beta.

Итак, приведу ниже код функции. Скачать PHP-файл можно здесь: mircChat2html.zip, mircChat2html.tar.gz. А online demo можно посмотреть тут.
