Need som help with php date calculations from mysql database

I'm trying to find out how to calculate dates. This is what I have found out:

Todays date is: <?php echo date("d.m.Y H:i:s"); ?>

Todays date + 2 weeks is: <?php echo date ('d.m.Y H:i:s', strtotime("+2 week")); ?>

Arrival date displayed from a database is <?php echo date ('d.m.Y H:i:s', strtotime($row_rsArrivals['arrivaldate'])); ?>

But what is Arrival date displayed from a database + 2 weeks ?

Regards
Rune

that would be:

php:
<?php echo date ('d.m.Y H:i:s'strtotime($row_rsArrivals['arrivaldate']."+ 2 week")); ?>

Thanks. Your suggestion works perfect.

I have another case. If the arrival date is more than 2 weeks old, the user should be redirected to another page, so I believe I have to use an if statement like this:

<?php if (date("d.m.Y H:i:s") > (date('d.m.Y H:i:s', strtotime($row_rsArrivals['arrivaldate']."+ 2 week")))) { ?>
<?php
header ( 'Location: redigering_stengt.php' ) ;
?>
<?php } ?>

But the user is not redirected, no syntax error in my if statement.

I'm attaching a file where I have put together an example. You can also see it on live URL here:

Untitled-2.php

Thanks

you have the if statement at line 1.

the recordset is not created till line 41.

you wont be able to use the data in the recordset in your if statement till the recordset is created by the code.

the if statement needs to be moved so it is after the recordset.

Yes, that make sense, but it's still not working.

I have moved the if statement below the recordset, I'm uploading a new version of the file. Live URL is also updated,

Untitled-2.php

Please have another look. Thanks in advice.

your dates are strings.

the less than operator is a mathematical operation.

you cannot perform math on a string data type, only on a number data type.

try using this for your if statement instead

php:
<?php if (time() > strtotime($row_rsMottattdato['mottatt_dato']."+ 2 week")) { ?>
