#Php sleep for 500 miliseconds code

This is different than running a standard 1 second sleep loop, due to sleeping longer does not consume as much CPU. I have some PHP code that stores variables into the cache using memcache and I would like to execute this code every 500 milliseconds whenever the server is running, even after a server restart. Note: This function throws an error if the specified number of seconds is negative. This is not a replacement for multi-threading, but it could help someone that wants to do something cheap. Definition and Usage The sleep () function delays execution of the current script for a specified number of seconds. is not included when determining the maximum time that the script has been running. Any time spent on activity that happens outside the execution of the script such as system calls using system(), the sleep() function, database queries, etc.

The setInterval () method continues calling the function until clearInterval () is called, or the window is closed. Note: The settimelimit() function and the configuration directive maxexecutiontime only affect the execution time of the script itself.
