How can echoing the query before execution help in troubleshooting PHP scripts?

Echoing the query before execution can help in troubleshooting PHP scripts by allowing you to see the exact SQL statement that is being sent to the database. This can help identify any syntax errors or unexpected values in the query, making it easier to debug and fix issues. 

$query = "SELECT * FROM users WHERE id = $user_id";

// Echo the query before execution
echo $query;

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

// Rest of the code to process the query result
