What are some alternative approaches to handling arrays in PHP forms for database insertion, besides serialization?

When handling arrays in PHP forms for database insertion, besides serialization, another approach is to loop through the array and insert each element individually into the database. This allows for more control over each element and can be useful when dealing with complex data structures.

// Assuming $array is the array to be inserted into the database
foreach($array as $element){
    // Insert $element into the database using your preferred method (e.g. PDO, mysqli)
}
