adding a week to a date problem

[rogercoathup]

I have written / copied a sample piece of code to add a week to a date, but am baffled by the output can anyone help:

<?php

$time = time ();

// add a week to the date
$dateArray = getdate ($time);
echo "now is: " .strftime("%d %B %Y", $time). "<p>";

$month = $dateArray['month'];
$day = $dateArray['mday'];
$year = $dateArray['year'];
$later = mktime (0,0,0, $month, $day+7, $year);

echo "one week later is: " .strftime ("%d %B %Y", $later);
?>

outputs:

now is: 25 March 2003
one week later is: 01 January 2003

Thanks!

i'm not sure i get your code at all. why not try something along the lines of:

$now = mktime();
$add_days = 7;
$new_time = ($add_days * 24*60*60);
echo $new_time."<br>";
$new_time += $now;
echo "One week from now is ".date("d M Y", $new_time);

thanks John... I realise I can add an appropriate number of seconds to a timestamp, but wanted something more human-readable, i.e. to see a 7 when you add 7 days.

My code is basically the same as that quoted in Glasshaus's book: Advanced PHP Web Development p.177, and in the article "Date Manipulation in PHP" from this site!

But there code gives the right answer!

Any further help on why mine is failing would be appreciated.

p.s.

mine fails on 2 different PHP installations: locally on my Win 200 setup, and also on a remote Sun Cobalt installation.

OK... have fixed it...

Thanks John for the timestamp suggestion.

The problem with my original code was the array indexing... to get the month, the index should be 'mon', not 'month'.

All now works fine.
