Are there any best practices for incorporating usleep in PHP scripts for real-time data display?

When incorporating usleep in PHP scripts for real-time data display, it is important to use it in conjunction with output buffering to prevent partial content from being displayed prematurely. By buffering the output, you can ensure that the data is displayed all at once after the usleep delay. This helps in creating a smoother real-time data display experience for users.

ob_start();

// Your real-time data display logic here

ob_end_flush();
usleep(500000); // Delay in microseconds (0.5 seconds)
