What are the advantages and disadvantages of using different data types, such as TIME or datetime, for storing time values in a MySQL database in a PHP application?

When storing time values in a MySQL database in a PHP application, using the TIME data type is suitable for storing time values without date information, while the datetime data type includes both date and time information. The advantage of using TIME is that it takes up less storage space, while datetime provides more flexibility in querying and displaying data. However, datetime can be more complex to work with due to the inclusion of date information. 

// Storing time values using TIME data type
$connection = new mysqli("localhost", "username", "password", "database");

// Inserting a time value
$timeValue = "12:30:00";
$query = "INSERT INTO table_name (time_column) VALUES ('$timeValue')";
$connection->query($query);

// Retrieving time values
$query = "SELECT time_column FROM table_name";
$result = $connection->query($query);
while ($row = $result->fetch_assoc()) {
    echo $row['time_column'] . "<br>";
}

$connection->close();
