What potential issue is the user facing when trying to send the generated file to the client after creation?

The potential issue the user may face when trying to send the generated file to the client after creation is that the file may not be properly downloaded by the client due to incorrect headers being set or other issues related to file transfer. To solve this issue, the user should ensure that the correct headers are set before sending the file to the client, such as specifying the content type and content disposition. 

// Set the content type and content disposition headers
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="generated_file.txt"');

// Output the file contents to the client
readfile('path/to/generated_file.txt');
