In what ways can browser behavior impact the output display when using the PHP flush() function in a script?

When using the PHP `flush()` function to send output to the browser incrementally, the browser's behavior can impact the display. Some browsers may not render content until a certain amount of data is received, causing delays in displaying content. To address this issue, you can use ob_flush() along with flush() to clear and flush the output buffer, forcing the browser to display content immediately. 

ob_start();
for ($i = 0; $i < 10; $i++) {
    echo "Output $i <br>";
    ob_flush();
    flush();
    sleep(1); // Simulate delay
}
ob_end_flush();
