Bot response to words in sentences?

Question

PHP

How to make the bot react to specific words in sentences of any length? The bot is written in php. It would be nice if you send the code

Answer 1

If it's simpler, then you can use the banal strpos , which will return you "not zero" if the string contains the substring you need.

$pos = strpos('бот реагировал на конкретные слова в предложениях', 'бот');
if ($pos === false) {
    echo "Подстрока не найдена";
} else {
    echo "Подстрока найдена";
}

Answer 2

preg_match()
