Here is my code, an output of 0 is expected after sleep() suceeded, but instead nothing is printed. can anyone tell me why, please?
Code: Select all
<?php
print "Hello Web!!!";
print "\n";
print sleep(8);
?>

In this case sleep should return with 0.
What do you get?

Try
print doesn't normally need the brackets, but it may make a difference

try:
That'll tell you exactly what's being returned

I'm not sure why you would ever want to use sleep() in an application.
