How can explicit type conversion be used in PHP to handle the return values of MySQL queries more effectively?

When handling the return values of MySQL queries in PHP, it is important to use explicit type conversion to ensure that the data is interpreted correctly. This can help avoid unexpected behavior or errors when working with the query results. By explicitly converting the data types, you can ensure that the values are used in the appropriate context within your PHP code. 

// Example of using explicit type conversion to handle MySQL query results
$query = "SELECT * FROM users WHERE id = 1";
$result = mysqli_query($connection, $query);

if ($result) {
    $row = mysqli_fetch_assoc($result);
    
    // Explicitly convert the 'id' field to an integer
    $id = (int) $row['id'];
    
    // Explicitly convert the 'name' field to a string
    $name = (string) $row['name'];
    
    // Use the converted values in your PHP code
    echo "User ID: " . $id . "<br>";
    echo "User Name: " . $name;
} else {
    echo "Error executing query: " . mysqli_error($connection);
}
