Does PHP\'s `sleep()` Function Count Towards Execution Time Limits?

Does Sleep Time Impact Script Execution Limits?

In PHP, the sleep() function halts script execution for a specified duration. Does this sleep period contribute to the overall script execution limit?

Answer:

The answer depends on the operating system.

Linux:
On Linux, sleep time is excluded from execution time limits. Therefore, if your PHP script has a 30-second execution limit and executes sleep(31), it will not terminate prematurely.

Windows:
In contrast, Windows considers sleep time as part of execution time. If you set a 30-second limit and use sleep(31), your script will exceed the threshold and terminate.

Additional Considerations:

• Test your script to verify the behavior on your specific system.
• Example code:

<?php
  sleep(ini_get('max_execution_time') + 10);  // Increase sleep time to exceed limit
?>
