What are some alternative approaches to sending a CSV file to the browser for download in PHP?

When sending a CSV file to the browser for download in PHP, one common approach is to use the header() function to set the appropriate content type and disposition headers. However, an alternative approach is to use the readfile() function to read the contents of the CSV file and output it directly to the browser.
