PHP mktime string not working

Question

I am trying to add $input to my $output mktime string but it just returns the date today not the date +2 days (eg 2 days ahead) as desired. Can anyone help my with this please?

 $input = '+2';
 $output = date('j',mktime(0,0,0,date('j'), date('d'),  $input  ,date('Y')));

I have also tried

$input = +2;
$output = date('j',mktime(0,0,0,date('j'), date('d'),  $input  ,date('Y')));

but that did not work either.

Any help would be much appreciated, thanks in advance.

Answer 1

You can do:

date('j', mktime(0, 0, 0, date('m'), date('d') + 2, date('Y')));

But the easier way would probably be (and more readable one):

$date = strtotime('+2 days');
$output = date('j', $date);

Answer 2

The coma before $input is messing with you. You should replace it with a + sign and only have the number of days in your $input. Like this:

$input = 2;
$output = date('j',mktime(0,0,0,date('j'), date('d') + $input,date('Y')));

But there are better ways to do this (see other answers).
