For the sake of simplicity, I will, in the rest of the posts, only speak about a waiting thread, although the future is indeed waiting. All promises and futures will be executed in different threads. Each future has a different waiting strategy. That’s possible because I used std::shared_future. The key idea of the program is that the promise provides its result for four shared futures.

C++14 has more literal for typical time durations. To the rescue, we have time literals in C++14, like 2s. Although I use auto it’s very verbose to define the time point in2min: auto in2min= std::chrono::steady_clock::now() + std::chrono::minutes(2). In2min stand for a time 2 minutes in the future. Here is a concise overview of sleeping, blocking, and waiting methods. I presented the time duration and time point in separate posts. Methods ending with _for having to be parametrized by a time duration member functions ending with _until by a time point. The methods for handling time in multithreading programs follow a simple convention. All four have in common that they can sleep, wait or block until a time point or for a duration. As well, as threads, locks, and condition variables understanding time. Don't forget to hire PHP developers with a strong understanding of PHP functions and best practices to ensure your project's success.The new time library is an important component of the threading interface. Whether you're simulating real-time processing, rate-limiting API requests, or simply pausing script execution, these functions are invaluable tools for PHP developers. In this tutorial, we covered the basics of using PHP's `sleep()` and `usleep()` functions to introduce time delays in your scripts. To stay within this limit, you can introduce a 1-second delay between requests using the `sleep()` function: To avoid hitting these limits, you can use the `sleep()` or `usleep()` functions to introduce a delay between requests.įor example, suppose you have an API that allows 60 requests per minute. Many APIs have rate limits, which restrict the number of requests you can make in a specific time frame (e.g., 60 requests per minute). ![]() One practical use case for the `sleep()` and `usleep()` functions is rate-limiting API requests. When you run the script, you'll notice a 0.5-second delay between the "Start" and "End" timestamps. Here's an example of using the `usleep()` function:Įcho "Start: ". The function takes an integer parameter, `$microseconds`, representing the number of microseconds to pause the script execution. The syntax for the `usleep()` function is as follows: However, the `usleep()` function allows you to specify the delay in microseconds (1 second = 1,000,000 microseconds) rather than seconds. Similar to the `sleep()` function, the `usleep()` function is used to introduce a delay in the execution of a PHP script. When you run the script, you'll notice a 3-second delay between the "Start" and "End" timestamps. Sleep(3) // Pause the script for 3 seconds Here's a simple example of using the `sleep()` function:Įcho "Start: ". The `sleep()` function returns zero on success, or `FALSE` on error. The function takes an integer parameter, `$seconds`, representing the number of seconds to pause the script execution. ![]() The syntax for the `sleep()` function is as follows: The `sleep()` function in PHP is used to delay the execution of a script for a specified number of seconds. Time delays are useful in various situations, such as when you need to pause script execution for a specific period or simulate real-time task processing. In this tutorial, we will learn how to use PHP's `sleep()` and `usleep()` functions to introduce time delays in your PHP scripts. ![]()
