In what situations should the "limit" clause be used when querying a database in PHP?

The "limit" clause should be used when you want to restrict the number of rows returned by a database query in PHP. This can be useful when dealing with large datasets to improve performance and reduce memory usage. By using the "limit" clause, you can specify the maximum number of rows to retrieve from the database, making your queries more efficient. 

// Example of using the "limit" clause in a MySQL query in PHP
$query = "SELECT * FROM users LIMIT 10";
$result = mysqli_query($connection, $query);

while ($row = mysqli_fetch_assoc($result)) {
    // Process each row here
}
