How can PHP developers address discrepancies in MIME type retrieval between PHP functions and server settings?

The issue of discrepancies in MIME type retrieval between PHP functions and server settings can be addressed by explicitly setting the MIME type in the PHP code using the header() function. This ensures that the correct MIME type is sent to the browser regardless of server settings.

// Set the MIME type to ensure consistency
header('Content-Type: text/html');
