How can the use of semicolons and proper syntax in PHP code prevent unexpected errors in database operations?

Using semicolons and proper syntax in PHP code is crucial for preventing unexpected errors in database operations. Incorrect syntax can lead to syntax errors or unexpected behavior when interacting with the database. By ensuring that each statement is properly terminated with a semicolon and following the correct syntax conventions, you can avoid these issues and ensure the smooth execution of database operations. 

// Example of proper syntax in PHP code for a database operation
$query = "SELECT * FROM users WHERE id = 1;";
$result = mysqli_query($connection, $query);

if ($result) {
    // Process the result
} else {
    // Handle the error
}
