[RESOLVED] Why does this not etc a $_SESSION

[NZ_Kiwis]

<?php
//header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
//header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
session_start();

if (isset($_SESSION['Date'])){
	$_SESSION['Date'] = strtotime("29/07/1998");
} 

$GameDate = $_SESSION['Date'];
$GameDate = strtotime(date("d/m/Y", strtotime($GameDate)) . "+1 month");

$_SESSION['Date'] = strtotime($GameDate);
echo $_SESSION['Date'];	

?>

What does "Why does this not etc a $_SESSION " mean?

I can see that strtotime("29/07/1998") is invalid because of the poor choice of format ([man]strtotime[/man] would try to interpret that as a U.S. date - see http://www.php.net/manual/en/datetime.formats.php; [man]mktime[/man] would be more straightforward). Likewise for the later (and redundantly complicated) strtotime(date(strtotime())) dance.

See also your earlier post where you try to work out how to add a month to a date.

Few questions:

1. What's your question? And what does "etc a $SESSION" mean?
   

2. You assign $_SESSION['Date'] to $GameDate without first checking to see that it exists. What happens if that value wasn't defined?
   

3. Why use the $GameDate variable at all? Seems highly superfluous in the code snippet above.
   

4. This:
   

   strtotime(date("d/m/Y", strtotime($GameDate)) . "+1 month");

   makes no sense. Why are you taking a Unix timestamp, formatting it as "d/m/Y", and then taking that formatted string and... converting it back into a Unix timestamp.

   In other words, why do something and then immediately undo it in the next operation (other than to making the code more convoluted and bloated than it needs to be 😉)?

I blame a new keyboard for my error in the subject. etc should have been echo

This is what I have, why does it not now echo a date formatted string?

<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
session_start();


// If not session date is found, set it to this date as a string to time
if (!isset($_SESSION['Date'])){
	$_SESSION['Date'] = strtotime("07-29-1998");
	echo "No session";
} 

// Format date (working from a time stamp
$NewGameDate = strtotime("+1 month", $_SESSION['Date']);

// Set session as raw data
$_SESSION['Date'] = $NewGameDate;

// Echo
echo strtotime(date("d/m/Y", $_SESSION['Date'])); 
?>

fixed, too tired for this

echo date("d/m/Y", $_SESSION['Date']);
