How can PHP developers prevent the creation of multiple database entries when submitting a form with empty array elements?

When submitting a form with empty array elements, PHP developers can prevent the creation of multiple database entries by checking if the array element is empty before inserting it into the database. This can be achieved by using conditional statements to skip empty array elements during the insertion process. 

// Assuming $dataArray is the array containing form data

foreach($dataArray as $data) {
    if(!empty($data)) {
        // Insert $data into the database
    }
}
