PHP provides various built-in functions and extensions to open a database. One of the commonly used extensions is MySQLi, which stands for MySQL Improved. This extension provides various functions to connect to a MySQL database.

To open a MySQL database using PHP, you can use the following code:

// Create a connection
$conn = mysqli_connect("localhost", "username", "password", "database_name");

// Check if the connection is successful
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

// Perform queries
$sql = "SELECT * FROM users";
$result = mysqli_query($conn, $sql);

// Close the connection
mysqli_close($conn);

In this example, we create a connection to the database using the `mysqli_connect()` function, passing in the hostname, username, password, and database name as arguments. We then check if the connection is successful using the `mysqli_connect_error()` function. We can then execute queries on the database using the `mysqli_query()` function, passing in the connection and the SQL query as arguments. Finally, we close the connection using the `mysqli_close()` function. The package library used in this example is the MySQLi extension for PHP.
