What is the significance of grouping data in PHP when working with databases like MySQL?

Grouping data in PHP when working with databases like MySQL is significant because it allows you to organize and manipulate data more efficiently. By grouping data, you can perform aggregate functions like SUM, COUNT, AVG, etc., on specific subsets of data. This can help you generate meaningful insights and reports from your database. 

// Grouping data in PHP using MySQL query
$query = "SELECT category, SUM(price) AS total_price FROM products GROUP BY category";
$result = mysqli_query($connection, $query);

while($row = mysqli_fetch_assoc($result)) {
    echo "Category: " . $row['category'] . " - Total Price: $" . $row['total_price'] . "<br>";
}
