In conclusion, the timesleepuntil() function is a powerful tool for creating precise timing delays in PHP scripts. You should also avoid calling the function too frequently or in performance-critical sections of your code.

Tweaking these settings can be immensely helpful, and anyone using apache should know how - just please make sure your hardware can handle the software configuration you set up. This study aimed to investigate the impacts of intermittent fasting during Ramadan and chronotype on sleep quality and aerobic performance in young athletes.

Both functions are supported by PHP 4 and.

This sleeping time could be controlled by a parameter, sent as an argument to this function.
As you posted in your own answer (and I'm glad it worked) increasing the number of allowed children can be a good solution - but there's a lot that goes into optimizing php-fpm, and certainly more thought should be given to the entire system before making these configuration changes.īut no matter what you should know when using static values: Like other languages, PHP sleep () is also used to pause program execution for a particular amount of time.
