Is it necessary to explicitly convert data types when handling MySQL query results in PHP?

When handling MySQL query results in PHP, it is not always necessary to explicitly convert data types as PHP is able to handle different data types automatically. However, it can be beneficial to explicitly convert data types for clarity and to ensure consistent handling of data. This can be especially important when dealing with numeric values or dates. 

// Example of explicitly converting data types when handling MySQL query results in PHP
$query = "SELECT id, name, age FROM users";
$result = mysqli_query($connection, $query);

while ($row = mysqli_fetch_assoc($result)) {
    $id = (int)$row['id']; // Explicitly convert id to integer
    $name = $row['name']; // No need to convert name
    $age = (int)$row['age']; // Explicitly convert age to integer

    // Use the converted data types as needed
    echo "ID: $id, Name: $name, Age: $age <br>";
}
