This PHP snippet enables the export of data from a database to a CSV file, facilitating reporting and data analysis. It is particularly useful for administrative interfaces where data needs to be exported for offline use or further processing.

The code demonstrates connecting to a database, retrieving data via a query, and writing this data to a CSV file in a format that can be easily opened with spreadsheet software.

Error handling ensures that the database connection is successful, and data retrieval does not encounter issues. It also checks file write permissions to avoid runtime errors.

The snippet can be adapted to various data sets and includes comments to aid in customization, making it versatile for different use cases requiring data export.

This functionality is essential for applications where data portability and offline access to data are required, enhancing the application's utility for end-users and administrators.
