What are some considerations for optimizing output buffering and flushing in PHP to ensure timely display of output in the browser?

Output buffering in PHP can help optimize the display of output in the browser by collecting the output before sending it to the client. To ensure timely display, it's important to flush the buffer periodically to send the accumulated output to the browser. This can be done using the ob_flush() function to flush the output buffer and ensure that content is displayed promptly. 

ob_start();

// Output buffering content
echo "Hello, World!";

// Flush the output buffer
ob_flush();
