king.oslo Posted May 31, 2009 Share Posted May 31, 2009 Hello my friends. I am just learning about sessions and I am trying to make a script that counts and prints the number of visits a user makes each session. My problem is that when I refresh the page for the first time and expecting the counter to go from "1 time" to "2 times" the only thing that happens is that the counter goes from "1 time" to "1 times". Please let me know what is wrong, and why Thanks <?php session_start(); if (isset($_SESSION['counter']) ){ $counter = $_SESSION['counter']++; $type = ' times'; } else { $counter = $_SESSION['counter'] = 1; $type = ' time'; } print 'You have visited this web site ' . $counter . $type . ' this session.' ?> Link to comment https://forums.phpfreaks.com/topic/160405-solved-problem-with-simple-script/ Share on other sites More sharing options...

king.oslo Posted June 1, 2009 Author Share Posted June 1, 2009 order of operation... Hey, I thought so too, but I did not think that moving the ++ further forward would change anything about the order of operation. How come?oz Link to comment https://forums.phpfreaks.com/topic/160405-solved-problem-with-simple-script/#findComment-846515 Share on other sites More sharing options...
