data fetch one-to-many relationship php

Comment

// Assuming we have two tables: 'users' and 'posts' with a one-to-many relationship (one user has many posts)

// Make a database connection
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database_name";
$conn = new mysqli($servername, $username, $password, $dbname);

// Check the connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Fetch all users with their related posts
$sql = "SELECT * FROM users
        LEFT JOIN posts ON users.id = posts.user_id";
$result = $conn->query($sql);

// Process the fetched data
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        // You can access the user and post data like this:
        $user_id = $row['id'];
        $user_name = $row['name'];
        $post_id = $row['post_id'];
        $post_title = $row['title'];
        // Process the data as needed
    }
} else {
    echo "No data found.";
}

// Close the connection
$conn->close();
