How to Generate a CSV File Using PHP?

Creating a CSV File in PHP

Many users of a database need to be able to access the contents of the database in various forms. In this case, a CSV file, or comma-separated value file, is needed.

To output a CSV file in PHP, the following steps can be taken:

1. Set the correct header information. This ensures that the file is correctly formatted. For a CSV file, this is done with the Content-Disposition header and a filename.
2. Create a function to output the CSV data. This function will take the data to be output as input and format it into a CSV string.
3. Call the function to output the CSV data. This will send the CSV data to the browser.

Example:

The header function is used to set the correct header information. The outputCSV function takes the data to be output as input and formats it into a CSV string. The fputcsv function is used to write the CSV data to the output stream.

Once this code is executed, the CSV file will be sent to the browser and downloaded by the user.
