Php date problem 'Y' displying 1969

Why is this code displaying 'Y' as 1969? :helpme

Quote:

<?php

$today = date("d");
$thisMonth = date("M");
$thisYear = date("Y");
echo date("M d Y", mktime(0,0,0, $thisMonth, $today, $today-8));

?>

I'm trying to get it to display: Jan 5 2023 (minus 8 days from today).

Because you have given the mktime() function a negative number for the year value.

So I need to take it out of the echo statement and display it within its own echo statement?

Or just remove the '0' for the year?

No, you need to understand what mktime() does and what parameters it expects.

https://www.php.net/manual/en/function.mktime.php

You are giving it a value for the day where it expects a value for the year.

It would be far easier to work with timestamps for this.

Code:

echo date("M d Y", time() - (86400 * 8));

Okay thanks for the suggestion and assistance, I appreciate it :thumbsup

this is wrong for so many reasons beyond just having your mktime parameters screwed up

how about when your $today-8 is an invalid day value? on the 7th $day-8 comes back as -1

also what is with splitting the date into pieces like that? you were doing that in the database table at one point too.

you are taking your date and converting it to 3 integers and then turning it back into a date, why?

every language has date functions to handle date calculations, php included

https://www.w3schools.com/php/php_ref_date.asp

handling it the way you are doing is basically trying to reinvent the wheel

Quote:

echo date("M d Y", time() - (86400 * 8));

that is a reasonable solution

i prefer to use datetime objects

in php you can add and subtract from a date pretty easily using the datetime object and associated functions

$mydate=date_create(date('Y-m-d',time())); // create the datetime object
date_sub($mydate, date_interval_create_from_date_string("8 days")); // subtract 8 days
echo date_format($mydate,"M d Y"); // display the result

https://www.w3schools.com/php/func_date_date_sub.asp

you could also use date_modify() for this

$date=date_create(date('Y-m-d',time()));
date_modify($date,"-8 days");
echo date_format($date,"Y-m-d");

https://www.w3schools.com/php/func_date_modify.asp

you should, at all times while working on this stuff have a browser window open to php.net and w3schools.com or other coding sites, just my opinion

I try

.

date('M d Y',strtotime("-8 days"));

The code is displaying 'Y' as 1969 because the third argument passed to the mktime() function is $today-8 instead of $thisYear.

Here is the corrected code:

Code:

<?php



$today = date("d");

$thisMonth = date("m");

$thisYear = date("Y");

echo date("M d Y", mktime(0,0,0, $thisMonth, $today-8, $thisYear));



?>

This will display the date 8 days ago in the format "Jan 6 2023".

Thank you all for the assistance with this i genuinely appreciate the advice and feedback :)
