What role does browser buffering play in the output of content generated by PHP scripts?

Browser buffering can sometimes cause issues with the output of content generated by PHP scripts, as it may prevent the content from being displayed in real-time. To solve this issue, you can use the `flush()` function in PHP to send the output to the browser immediately, bypassing any buffering.

// Enable output buffering
ob_start();

// Your PHP script generating content

// Flush the output to the browser
flush();

// Clear the output buffer
ob_end_flush();
