This is the only part of my project to give me any trouble and I have been searching for help and trying things out for two straight days. I just need to throttle the output so as not to exceed the 500/hr limit. php ', but if so, it will type' Server found ', wait 2 seconds (which is important) and load the server panel (sp.php). 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.The script and cronjob function perfectly as I have them currently. Hi, I try that when the user visits the page cns.php (The page to which I try to add sleep () ), it first detects if the cookie 'sc' (Server created) has been set, and if not, loads the content from the file 'noserver. The above script could be rewritten like this: 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. The loop continuously executes until the condition is false. Note: This function throws an error if the specified number of. A call to the sleep( ) function might be placed at the end of a loop, so that after the code inside the loop has been run, a certain amount of time passes before the loop executes again. The sleep() function delays execution of the current script for a specified number of seconds. For example, sleep (0.25) will pause program execution for 0 seconds. For example, if you wanted to sleep your PHP script for a quarter of a second. A microsecond is one-millionth of a second. However, if the function contains a loop you can add in your own code to interrupt the loop after a certain condition has been met. usleep () is used to delay execution in 'microseconds' while sleep () is used to delay execution in seconds. usleep () allows your code with respect to microseconds. sleep () allows your code to sleep in seconds. With this function, you can specify the number of microseconds you want the script to sleep. Meaning processing will not continue until the current function has completed. If there's a performance difference, it's almost certainly negligible and not worth updating the answer over. Note: In order to delay program execution for a fraction of a second, use usleep () as the sleep () function expects an int. If you need to pause the execution of your PHP script for times shorter than a second, you will need to use the usleep () function. condition - Evaluate each iteration value. Delaying, sleeping, or pausing PHP script execution is commonly used when scheduling an event. Delays the program execution for the given number of seconds. The initial value of the for loop is done only once. The parameters of for loop have the following meanings: initialization - Initialize the loop counter value. Firstly, time() has a very low precision, only returning the number of whole seconds that have passed, which makes the whole thing quite vague. The php for loop is similar to the java/C/C++ for loop. While it does work, there are two problems with it. You can achieve the infinite-loop in PHP which. You can try playing with obgetcontents () to retrieve the output buffer on each iteration. However, what you are seeing is the output sent to the browser, which is buffered and delivered by PHP at certain times (normally when the script execution finishes). Some people (thankfully very few) choose the first option and write code like this: I tried doing a SCredir at the end of my application redirecting back to itself with a 5 second SLEEP command. Every iteration of the loop is being delayed 5 seconds. When you want to pause execution in your script, there are two ways you can implement the code.
