In the example code, we will import members data from CSV file in the database using CodeIgniter CSVReader library. The following process will be implemented to demonstrate the CodeIgniter CSV Import<\/b> functionality.<\/p>\n Before getting started to implement the import CSV file to the database in CodeIgniter 3.x application, take a look at the files structure.<\/p>\n To store the member’s data, a table is needed in the database. The following SQL creates a Based on the database table structure, the CSV file will have the 4 fields – Name, Email, Phone, Status. The format of the CSV file will similar to the following screen.<\/p>\n autoload.php<\/b> CSVReader.php<\/b>\n
