date / time

[Digiboy]

hi guys, 

 

Im trying to calculate number of days and time passed a time stamp but I always get 0 do you know why? 

 

Am I making funny mistake again?

        date_bought= "2013-06-02 15:57:04";
	$add_days = 7;
        $date= date('Y-m-d',strtotime( $date_bought) + (24*3600*$add_days));
        $result_date= $date - $date_bought;
	echo"$result_date";

 $result_date= $date - $date_bought;

You cant do this. You are trying to substract two strings.

 

Also, even if you got this to work, with the current math the answer will always be 7 days.

This will substract two dates and give you the difference in hours/minutes. Like DaveyK said if you add 7 days to a timestamp then subtract the original timestamp from it. You will always get exactly 7 days.

$diff = strtotime($timestamp2) - strtotime($timestamp1);
$hours = floor($diff / 3600);
$diff %= 3600;
$minutes = floor($diff / 60);

You really shouldn't use math to calculate these things or you get into daylight savings time troubles:

$date = date('Y-m-d', strtotime("+ $add_days days", strtotime($date_bought)));
