Mark Baker Posted April 10, 2009 Share Posted April 10, 2009 Get out of the habit of quoting everything. If you want to add two numbers together use: $new = $time + $timeout; not $new = "$time + $timeout"; Also ensure that you are actually setting $_SESSION['time'] Link to comment https://forums.phpfreaks.com/topic/153458-php-maths-help/#findComment-806243 Share on other sites More sharing options...

Mark Baker Posted April 10, 2009 Share Posted April 10, 2009 if ($time = $new) { will set the value of $time to the value of $new, and then execute the if logic if ($time == $new) { will compare the value of $time with the value of $new and only execute the if logic if the two values are equal Link to comment https://forums.phpfreaks.com/topic/153458-php-maths-help/#findComment-806246 Share on other sites More sharing options...

Mark Baker Posted April 10, 2009 Share Posted April 10, 2009 correct, iv changed it and all i get now is 1239358810 1239358810 + 2 Have you still got $new = "$time + $timeout"; because $time and $new shouldn't match, so the if condition shouldn't be met, so you should actually see nothing Link to comment https://forums.phpfreaks.com/topic/153458-php-maths-help/#findComment-806255 Share on other sites More sharing options...

Mark Baker Posted April 10, 2009 Share Posted April 10, 2009 this is the code, but i cant get no results here You won't see any results because you're only printing results if $time and $new are the same... but they're not going to be the same because $new is 2 more than $time if ($time == $new) { print $time.' and '.$new.' are the same'; } else { print $time.' and '.$new.' are not the same'; } Link to comment https://forums.phpfreaks.com/topic/153458-php-maths-help/#findComment-806583 Share on other sites More sharing options...
