In what situations can using sprintf function be beneficial in constructing SQL queries in PHP?

When constructing SQL queries in PHP, using the sprintf function can be beneficial to safely insert variables into the query string without risking SQL injection attacks. By using sprintf, you can ensure that variables are properly formatted and escaped before being included in the query, reducing the risk of malicious code being injected into the query. 

// Example of using sprintf to construct a SQL query safely
$user_id = 1;
$status = 'active';

$query = sprintf("SELECT * FROM users WHERE user_id = %d AND status = '%s'", $user_id, $status);

// Execute the query using your database connection
$result = mysqli_query($connection, $query);

// Process the query result as needed
