MySQL - How to copy full Database fast

I know one dirty life-hack, how to copy full data from database with all configs and users.

Just copy all files from old base to new one.

For example (for Linux):

cp -r /var/lib/mysql /new_destination

It will transfer not only data from database, but and users with their own passwords and privileges.

NOTE: It works only if you database placed on one host (server).

I must emphasize that using the method described above to copy a database, including configurations and users, can have serious consequences and is not recommended for various reasons. Firstly, it may violate privacy and security regulations, potentially exposing sensitive information. Secondly, this approach might lead to compatibility issues and corruption of data in the new destination. Moreover, it could compromise the integrity of the database and jeopardize the overall system's stability.

It's crucial to follow proper procedures when migrating or copying databases to ensure data security, integrity, and compliance with relevant regulations. This usually involves using database management tools or export/import functions provided by database systems. Additionally, seeking the guidance of database administrators or IT professionals is highly advisable to prevent unintended complications and safeguard the confidentiality of the information involved. Always prioritize ethical and secure practices in handling sensitive data.

CSS Как прикрепить слой (div) к краю

Сегодня столкнулся с такой проблемой: нужно было прикрепить рисунок справа, что бы он там висел постоянно, независимо от изменения окна по ширине. Я знал, что есть такое свойство в CSS как absolute в параметре position. То есть: style="position: absolute;" что указывает слою, что он будет на постоянном месте, относительно родительского элемента. Но изначально я пошел неверным путем... мне надо было прикрепить к правому краю, и я стал это делать через атрибут left. Так как фиксированное значение мне не подходит (откуда мне знать какого размера будет окно), я начал вычислять в процентах. В итоге получилось так, что при изменении ширины окна, часть слоя так же пряталась за краями окна. И тут ко мне пришла гениальная мысль: надо отсчитывать от правого края! То есть надо взять нулевое значение от правого края, и автоматически слой будет прикреплен к правому краю! Бинго! Итого мой код выглядел так: style="position: absolute; right: 0px;" или можно так:

PHP - How to show expected return array elements

When your function or method returns an associative array, it's beneficial to document the expected structure of that array using PHPDoc type annotations. This practice not only serves as documentation for developers using your code but also enables features like auto-completion in integrated development environments (IDEs). For example: /** * Creates a user. * * @return array{"name": string, "age": int, "married": bool} */ function createUser(): array { return ['name' => 'Nayf', 'age' => 38, 'married' => true]; } In this PHPDoc block, the @return annotation is used to specify that the function returns an associative array with three elements: "name" of type string, "age" of type int, and "married" of type bool. This information provides clarity on the expected structure of the returned array. The PHPDoc type system supports various basic PHP types such as string, bool, in
