How can PHP beginners effectively manage relational databases and tables for storing image data?

To effectively manage relational databases and tables for storing image data in PHP, beginners can use SQL queries to create tables with appropriate fields for storing image data, such as image name, file type, and file size. They can also use PHP functions to upload images to the server and store the image data in the database. 

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);

// Create a table for storing image data
$sql = "CREATE TABLE images (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    image_name VARCHAR(50) NOT NULL,
    file_type VARCHAR(10) NOT NULL,
    file_size INT(10) NOT NULL
)";

if ($conn->query($sql) === TRUE) {
    echo "Table images created successfully";
} else {
    echo "Error creating table: " . $conn->error;
}

// Upload image and store data in the database
$imageName = $_FILES['image']['name'];
$fileType = $_FILES['image']['type'];
$fileSize = $_FILES['image']['size'];

$sql = "INSERT INTO images (image_name, file_type, file_size) VALUES ('$imageName', '$fileType', '$fileSize')";

if ($conn->query($sql) === TRUE) {
    echo "Image data stored successfully";
} else {
    echo "Error storing image data: " . $conn->error;
}

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