string mysql_field_flags ( resource result, int field_offset )

mysql_field_flags() возвращает флаги указанной колонки. Каждый флаг возвращается как отдельное слово отделённое от предыдущего пробелом. Полученное значение можно разбить в массив, используя функцию explode()

Возвращаются следующие флаги (если ваша версия MySQL уже содержит работу с ними): "not_null", "primary_key", "unique_key", "multiple_key", "blob", "unsigned", "zerofill", "binary", "enum", "auto_increment", "timestamp".

Для совместимости, как алиас, доступна устаревшая функция mysql_fieldflags(). Однако, использовать её крайне не рекомендуется.
