if current time is more then 24 hours past starting time

listenmirndt

trying to figure out how to check if more then 24 hours have past since a certain time.

ie:

set time
(format HH:MM/DD/MM/YYYY)

23:59/11/05/2011

so if current time is greater then 24 hours past set time...

how would that be coded?

thanks!

$startime = "2011-05-11 23:59";
$starttime = strtotime($starttime);
$oneday = 60*60*24;
if( $starttime < (time()-$oneday) ) {
   echo 'more than one day since start';
} else {
   echo 'started within the last day';
}

$startime = "2011-07-23 23:59"; //(today)
$starttime = strtotime($startime);
$oneday = 606024;
if( $starttime < (time()-$oneday) ) {
echo 'more than one day since start';
} else {
echo 'started within the last day';
}

is returning "1311397199" (seconds)

86400 is in 24 hours.

seems like way too many seconds difference... not sure why this would be

1311397199 is a unix time stamp, standing for the number of seconds since the epoch (Jan 1, 1970) and in this case it refers to 2011-7-22 23:59. 86400 is the number of seconds in 24 hours. So subtracting that number from the current time stamp (retrieved via the time() call) will give you the time in seconds 24hours ago.

No, it isn't.

A function may return a value, or rather, it always will. When no return value is supplied, there is always an implicit return null.

An included/required file may return a value, or rather, include/require always will return a value (although they are language constructs and nor functions). If the included/required file returns a value, include/require returns this value. Otherwise include/require returns 1 to indicate succecss.

However the code you showed is, as far as we can tell doesn't contain a return statement, and is most likely not part of a function. And if that code is part of a function, the function is returning null (unless there is even more code you didn't supply), and I'd rather expect the function to return boolean true/false for more/not-more than one day passed, since that would make the function useful in more cases than when you want to echo "more than 1 day", such as allowing users to edit their posts which are less than one day old.
