What is the significance of processing data sets in PHP when working with MySQL tables?

When working with MySQL tables in PHP, processing data sets is crucial for tasks such as fetching, updating, inserting, or deleting records. This involves executing queries, fetching results, and handling them appropriately within the PHP script. By processing data sets effectively, developers can interact with MySQL tables seamlessly and perform operations efficiently. 

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

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

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

// Example query to fetch data from a MySQL table
$sql = "SELECT * FROM table_name";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "id: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
