What I want is that all code before the sleep command gets executed, and 10 secs later, the above gets fired. (here´s where the other users are being informedīut sadly all the code in the whole php script is not executed till after the 10 seconds sleep. $newtime = $sql->fetch(PDO::FETCH_COLUMN) Tests that behave differently depending on existing classes, for example Composers. $sql =$conn->prepare ("SELECT time FROM Users WHERE username = ? limit 1") Using PHPs sleep(10) will make your test wait for 10 actual seconds (more. $oldtime = $sql->fetch(PDO::FETCH_COLUMN) Normally MySQL supports stacked queries but because of database layer in most of the configurations its not possible to execute a second query in PHP-MySQL. So this is what I did, at the end of the script: $sql =$conn->prepare ("SELECT time FROM Users WHERE username = ? limit 1") So I thought that if the php script that is called by the app each 5 seconds checks for whether if the timestamp in the sql table at the time the php script is called is the same 10 seconds later, then the other users will be told that he´s gone offline. This is done easily for situations where the user decides to logoff in the application, but if the users wifi goes down, for instance, obviously the app won´t be able to tell the other users that he´s no longer online.Įach 5 secs, there´s a check done by the app for new messages, which also updates a mysql with a current timestamp for each user.

#Php sleep alternative update
If this is the case, the status of the client is changed to offline because during those 10 seconds, there should have been an update to the timestamp in the table - unless. To learn more, check out our page on it here.
