date_diff

[markii.borabon_1]

im trying to get the date diff:

<?php
$datetime1 = date_create(date('d - M - Y'));
$datetime2 = date_create($date);
$interval = date_diff($datetime1, $datetime2);
$diff = $interval->format('LISTED %R%a DAY(S) AGO');
?>

it works in my localhost host.. but when I upload and run it online it get this error :

Fatal error: Call to undefined method DateTime::diff()

please help; =(
thnx

Chech the version of the remote PHP. DateTime::diff requires version 5.3.*+

• http://php.net/manual/en/datetime.diff.php

so it means my web host is not yet updated? =(

Make sure which version of PHP is in use in your host, you can use phpinfo(): http://php.net/manual/en/function.phpinfo.php and if you can upgrade.

For an alternative solution check the comments in the linked documentation, there are some examples with DateTime and strtotime().

In addition you can execute the same operation in MySQL, examples:

> select datediff(now(), date_sub(now(), interval 3 month)) days;
+------+
| days |
+------+
|   92 |
+------+
1 row in set (0.00 sec)

> select datediff(now(), '2014-08-15') days;
+------+
| days |
+------+
|   42 |
+------+
1 row in set (0.00 sec)

So it depends from where this information comes from (database, users forms) and what you want to achieve.

Try this it's working perfectly.

<?php
    $start_date='some date';
    $end_date='some date';
    $interval = new DateInterval("P1D");
    $begin = new DateTime($start_date);        
    $end = new DateTime( $end_date);
    $period = new DatePeriod($begin, $interval,$end);
    print_r($period);
?>

Probalby this does not help because both DateInterval and DatePeriod require PHP 5.3.* as DateTime::diff

• http://php.net/manual/en/class.dateinterval.php
• http://php.net/manual/en/class.dateperiod.php

Bye!

It will help u.It Working below php5.3

<?php
        function dateDifference($startDate, $endDate)
        {
            $startDate = strtotime($startDate);
            $endDate = strtotime($endDate);
            if ($startDate === false || $startDate < 0 || $endDate === false || $endDate < 0 || $startDate > $endDate)
                return false;

            $years = date('Y', $endDate) - date('Y', $startDate);

            $endMonth = date('m', $endDate);
            $startMonth = date('m', $startDate);

            // Calculate months
            $months = $endMonth - $startMonth;
            if ($months <= 0)  {
                $months += 12;
                $years--;
            }
            if ($years < 0)
                return false;

            // Calculate the days
                        $offsets = array();
                        if ($years > 0)
                            $offsets[] = $years . (($years == 1) ? ' year' : ' years');
                        if ($months > 0)
                            $offsets[] = $months . (($months == 1) ? ' month' : ' months');
                        $offsets = count($offsets) > 0 ? '+' . implode(' ', $offsets) : 'now';

                        $days = $endDate - strtotime($offsets, $startDate);
                        $days = date('z', $days);   

            return array($years, $months, $days);
        }
?>

Hi just a stupid question do you have a default timezone included or activated? if no include in it at the beginning your your code or activate it on your server.

date_default_timezone_set('Asia/Manila');
$date="10-10-2014";
$datetime1 = date_create(date('d - M - Y'));
$datetime2 = date_create($date);
$interval = date_diff($datetime1, $datetime2);
echo $diff = $interval->format('LISTED %R%a DAY(S) AGO');

The easiest and good method to claculate exact date time is TIMESTAMP.
claculate time stamp of first date and second date then subtrac them that will be your required date in the form of time TIMESTAMP cgange it to human read able form using TIMESTAMP functions

<?php 
//Our dates
$date1 = "2013-03-01 19:12:45";
$date2 = "2014-03-01 06:37:04";

//Convert them to timestamps.
$date1Timestamp = strtotime($date1);
$date2Timestamp = strtotime($date2);

//Calculate the difference.
$difference = $date2Timestamp - $date1Timestamp;

echo $difference;
?>
