![]() flavour is implicitly treated as a required parameter in example.php on line. Note that the default maximum script execution time is 30 seconds, but you can use sleep() and usleep() to make your scripts go on for longer than that because technically PHP does not have control during the sleep operation. However, write access to the entire GLOBALS array is no longer supported. It must construct and return an associative array of key/value pairs that represent the serialized form of the object. The above script could be rewritten like this: serialize() checks if the class has a function with the magic name serialize().If so, that function is executed prior to any serialization. Using either of them is far more accurate than the previous time() loop, and they both have their advantages - sleep() is better if you do not need the accuracy, and usleep() is better if you do. The difference between sleep() and usleep() is that sleep() takes a number of seconds as its parameter, whereas usleep() takes a number of microseconds - millionths of a second - as its parameter. A much better solution is to use the one of the two script sleep functions, sleep() and usleep(), which take the amount of time to pause execution as their only parameter. Secondly, PHP has to sit there looping thousands of times while it waits, essentially doing nothing. Firstly, time() has a very low precision, only returning the number of whole seconds that have passed, which makes the whole thing quite vague. While it does work, there are two problems with it. ![]() Some people (thankfully very few) choose the first option and write code like this: When you want to pause execution in your script, there are two ways you can implement the code. ![]()
