How can server settings impact the effectiveness of using flush and ob_flush functions in PHP scripts?

Server settings, such as output buffering and compression settings, can impact the effectiveness of using flush() and ob_flush() functions in PHP scripts. If output buffering is enabled or compression settings are in place, these functions may not work as expected. To resolve this, you can disable output buffering and compression settings before using flush() or ob_flush(). 

// Disable output buffering
ini_set('output_buffering', 'off');
ini_set('zlib.output_compression', false);

// Flush output
ob_end_clean();
flush();
ob_flush();
