to implement a webserver lamp stack but when i try to run index.php to connect from php to mysql like this:

<?php

try {
    $dbh = new PDO(
        'mysql:mysql:3308;dbname=minos',
        'minos',
        '1qazxsw22',
        array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION)
    );
} catch (PDOException $e) {
    echo $e->getMessage();
}

i get this error:

could not find driver

What do I need to change in my code or installation to remove this error of conecctivity?

Try running like this:

RUN apt update \
    && apt -y --no-install-recommends install php-mysql php-curl php-intl php-gd php-common php-redis php-sodium git \
    && apt-get clean; rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/*

Change form php8.1-lib to php-lib
