Sleep - Manual, After each time the sleep is done, use flush () and ob_flush () to flush the output buffer. To sleep for a quarter of a second, use: The difference between sleep () and usleep () is that sleep () takes a number of seconds as its parameter, whereas usleep () takes a number of microseconds - millionths of a second - as its parameter. The 0.25 is cast to an integer, so this is equivalent to sleep(0). This may seem obvious, but I thought I would save someone from something that just confused me: you cannot use sleep() to sleep for fractions of a second. The usleep() function delays execution of the current script for a specified number of microseconds (a microsecond equals one millionth of a second). This takes input as for date in sleep() mode for 5 seconds and then start again once the halt completes for 3 seconds and behaves merely different as compared to usleep as shown in the output. However, we are not concerned with the activity of sleep per se but the use of the word. This program demonstrates the difference in both the usleep() and sleep() function with the difference in CPU circle consumption. Sleep is characterized by reduced consciousness and reduced ability to perceive external stimuli. Sleep is a natural state that occurs when a human being is tired and tries to get some rest.

yield relinquishes the CPU to another thread, but may return immediately if there are no other threads that waits for CPU. When calling sleep the process/thread gives CPU to another process/thread for the given amount of time.
