What is the purpose of using the LIMIT clause in MySQL when retrieving data in PHP?

The LIMIT clause in MySQL is used to restrict the number of rows returned in a query result. This can be useful when dealing with large datasets to improve performance and reduce the amount of data transferred. In PHP, using the LIMIT clause can help optimize queries and ensure that only the necessary data is retrieved. 

// Connect to MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Query to retrieve data with LIMIT clause
$query = "SELECT * FROM table_name LIMIT 10";

// Execute query
$result = mysqli_query($connection, $query);

// Fetch and display results
while($row = mysqli_fetch_assoc($result)) {
    echo $row['column_name'] . "<br>";
}

// Close connection
mysqli_close($connection);
