What are the characteristics of the usleep function in …

The characteristics of the usleep function in PHP are as follows:

1. The usleep function can be used to pause the execution of a script for a specific period of time, with the unit being microseconds (1 second equals 1000000 microseconds).
2. The usleep function can take an integer as a parameter to indicate the number of microseconds to pause.
3. The usleep function will put the script to sleep, and will only continue executing the subsequent code after the specified time has passed.
4. – The usleep function is a blocking function, meaning that while it is executing, the script cannot perform other operations.
5. The usleep function is very useful for debugging and simulating specific scenarios, allowing for the simulation of delays or control of the program’s execution speed.
6. The usleep function can be combined with other functions or conditions to achieve certain control logic and flow control.
