How can PHP scripts send intermediate results to the browser for display while processing?

To send intermediate results to the browser while processing in PHP, you can use output buffering. This allows you to capture the output generated by your script and send it to the browser at specific points during execution. By using functions like ob_start() to start output buffering and ob_flush() to send the buffered output to the browser, you can display intermediate results as your script continues to process. 

<?php
ob_start();

// Processing code
echo "Processing step 1...<br>";
ob_flush();

// More processing code
echo "Processing step 2...<br>";
ob_flush();

// Final processing code
echo "Processing complete!";
ob_end_flush();
?>
