Are there any best practices for handling data types when retrieving values from a MySQL database in PHP?

When retrieving values from a MySQL database in PHP, it's important to handle data types properly to avoid unexpected results or errors. One common issue is that MySQL may return data in a different format than expected, such as returning a numeric value as a string. To solve this, you can use PHP functions like intval(), floatval(), or strtotime() to convert the data to the correct data type. 

// Example of handling data types when retrieving values from a MySQL database in PHP

// Assuming $result is the result set from a MySQL query
while ($row = mysqli_fetch_assoc($result)) {
    $id = intval($row['id']); // Convert 'id' to an integer
    $name = $row['name']; // 'name' is assumed to be a string
    $price = floatval($row['price']); // Convert 'price' to a float
    $created_at = strtotime($row['created_at']); // Convert 'created_at' to a Unix timestamp
}
