PHP has a built-in function called "mysqli_query" for retrieving data from a database. This function is used to execute an SQL query and retrieve the data returned by the query. However, a more efficient way to retrieve data from a database is to use a data access layer like PDO (PHP Data Objects) or a database abstraction layer like Doctrine.

Here are some examples of retrieving data from a database using various packages and libraries:

1. PDO: PDO is a data access layer that provides a unified API for connecting to and working with databases in PHP. Here's an example of retrieving data from a MySQL database using PDO:

// Connect to database
$db = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Prepare SELECT statement
$stmt = $db->prepare("SELECT * FROM mytable WHERE id = :id");

// Bind parameters and execute query
$stmt->bindParam(':id', $id);
$stmt->execute();

// Fetch data
$data = $stmt->fetchAll(PDO::FETCH_ASSOC);

2. Doctrine: Doctrine is a popular object-relational mapping (ORM) library for PHP. It provides a powerful way to work with databases by mapping database tables to PHP classes. Here's an example of retrieving data from a MySQL database using Doctrine:

// Configure database connection
$config = new \Doctrine\DBAL\Configuration();
$connectionParams = array(
    'dbname' => 'mydatabase',
    'user' => 'username',
    'password' => 'password',
    'host' => 'localhost',
    'driver' => 'pdo_mysql',
);
$conn = \Doctrine\DBAL\DriverManager::getConnection($connectionParams, $config);

// Prepare SELECT statement
$stmt = $conn->prepare("SELECT * FROM mytable WHERE id = :id");

// Bind parameters and execute query
$stmt->bindValue(':id', $id);
$stmt->execute();

// Fetch data
$data = $stmt->fetchAll(\PDO::FETCH_ASSOC);

In summary, retrieving data from a database in PHP can be done using various libraries and packages such as PDO or Doctrine. The code examples provided show how to execute a SELECT statement, bind parameters, and fetch data from a MySQL database.
