What is the usage of the sleep function in PHP?

In PHP, the sleep function is used to pause the execution of a script for a specified amount of time. Here is how it is used:

Pause for a specific number of seconds before continuing.

The variable “seconds” represents the amount of time to pause, measured in seconds. This function will pause the script’s execution until the specified amount of time has elapsed before continuing with the code below. For example, the following code will pause the script for 5 seconds:

Pause for 5 seconds.

Please note that the sleep function is restricted by the max_execution_time setting in the PHP configuration file. If the specified time exceeds this limit, the script will be terminated when it reaches the maximum execution time.
