Need fix for the codesniffer warning "The use of function sleep() is discouraged (Magento2.Functions.DiscouragedFunction.Discouraged)"

Question

When I run PHP Code sniffer on my code, I see the below warning.

WARNING | The use of function sleep() is discouraged (Magento2.Functions.DiscouragedFunction.Discouraged)

Which class method provides an alternative for the sleep() method in Magento 2 framework that fixes the above warning and follows the magento best practice.

Answer 1

Modify the code from

sleep(<time>);

to

// phpcs:ignore Magento2.Functions.DiscouragedFunction
sleep(<time>);

This is just a temporary solution where in the codesniffer ignores the evaluation of the discouraged function when prepended with the comment phpcs:ignore Magento2.Functions.DiscouragedFunction

Answer 2

I have found solution. We have to use usleep function which is working same like sleep function.

Only difference is that usleep function works in microseconds so you have to covert second into microsecond and it's work like a charm.

For example:-

sleep(2); //2 seconds delay here
usleep(2000000);  //2000000 microseconds = 2 seconds
