Are there any specific functions in MySQL that can be directly address the issue of querying data from multiple tables in PHP?

When querying data from multiple tables in MySQL using PHP, the JOIN clause can be used to combine rows from two or more tables based on a related column between them. By using JOIN, you can retrieve data from multiple tables in a single query and manipulate the results as needed. 

<?php
// Establish a connection to the MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Query data from multiple tables using JOIN
$query = "SELECT users.username, orders.order_id FROM users JOIN orders ON users.user_id = orders.user_id";
$result = mysqli_query($connection, $query);

// Fetch and display the results
while ($row = mysqli_fetch_assoc($result)) {
    echo "Username: " . $row['username'] . ", Order ID: " . $row['order_id'] . "<br>";
}

// Close the connection
mysqli_close($connection);
?>
