Are there specific PHP functions or methods that can help in retrieving data from separate tables without direct links between them?

When you need to retrieve data from separate tables without direct links between them, you can use SQL JOIN queries in PHP to combine the data from multiple tables based on a related column. By using JOIN queries, you can retrieve data from different tables that have a common column or relationship, allowing you to fetch related data in a single query. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";
$conn = new mysqli($servername, $username, $password, $dbname);

// SQL query to retrieve data from two separate tables using JOIN
$sql = "SELECT orders.order_id, orders.order_date, customers.customer_name
        FROM orders
        JOIN customers ON orders.customer_id = customers.customer_id";

$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Order ID: " . $row["order_id"]. " - Order Date: " . $row["order_date"]. " - Customer Name: " . $row["customer_name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
