This PHP script allows users to export data from a MySQL database table to a CSV file and import data from a CSV file into a MySQL database table. The script connects to a database, retrieves data from a specified table, and outputs it to a CSV file for export. For import, it accepts an uploaded CSV file, reads the data, and inserts rows into the database table. The code includes functions for database connection, selecting the table, retrieving and outputting column names and row data for export, and parsing, sanitizing, and inserting the CSV data for import.
