Finding days between 2 unix timestamps in php

Hay, i have a database holding events. There are 2 fields 'start' and 'end', these contain timestamps. When an admin enters these dates, they only have the ability to set the day,month,year. So we are only dealing with stamps containing days,months,years, not hours,minutes,seconds (hours,minutes and seconds are set to 0,0,0).

I have an event with the start time as 1262304000 and the end time as 1262908800. These convert to Jan 1 2010 and Jan 8 2010. How would i get all the days between these timestamps? I want to be able to return Jan 2 2010 (1开发者_JAVA技巧262390400), Jan 3 2010 (1262476800) .. all the way to the end stamp. These events could cross over into different months, say May 28 to June 14.

Any ideas how to do this?

You just have to calculate the number of seconds between the two dates, then divide to get days :

$numDays = abs($smallestTimestamp - $biggestTimestamp)/60/60/24;

Then, you can use a for loop to retrieve the dates :

$numDays = abs($smallestTimestamp - $biggestTimestamp)/60/60/24;

for ($i = 1; $i < $numDays; $i++) {
    echo date('Y m d', strtotime("+{$i} day", $smallestTimestamp)) . '<br />';
}

Again, if you don't know which timestamp is the smallest, you can use the min() function (second argument in strtotime).

I think that a quick workaround for this is to subtract the amount of a days worth of seconds from the end_stamp until you get to the start_tag.

//1 day = 86400 seconds

I would build an array of the days to use later.

EDIT (example)

$difference = 86400;
$days = array();
while ( $start_time < $end_time )
{
    $days[] = date('M j Y', $end_time);

    $end_time -= $difference;
}

This should cover any time frame even if its over a bunch of months.

Try this:

while($date_start <= $date_end) {
    echo date('M d Y', $date_start) . '<br>';
    $date_start = $date_start + 86400;
}

Hope this helps !

$d1=mktime(22,0,0,1,1,2007);
$d2=mktime(0,0,0,1,2,2007);
echo "Hours difference = ".floor(($d2-$d1)/3600) . "<br>";
echo "Minutes difference = ".floor(($d2-$d1)/60) . "<br>";
echo "Seconds difference = " .($d2-$d1). "<br>";


echo "Month difference = ".floor(($d2-$d1)/2628000) . "<br>";
echo "Days difference = ".floor(($d2-$d1)/86400) . "<br>";
echo "Year difference = ".floor(($d2-$d1)/31536000) . "<br>";

$daysInBetween = range($startTs, $endTs, 86400);
$secondDay = date('M d Y', $daysInBetween[1]);
/*
$thirdDay = date('M d Y', $daysInBetween[2]);
...
*/

Note that the range() function is inclusive.

    **This is a very simple code for find days hours minutes and seconds in php**

    $dbDate = strtotime("".$yourbdDate.""); // Database date
    $endDate = time();    // current time
    $diff = $endDate - $dbDate; /// diffrence

    $days = floor($diff/86400);  ///  number of days 
    $hours = floor(($diff-$days*86400)/(60 * 60));  ////  number of hours
    $min = floor(($diff-($days*86400+$hours*3600))/60);///// numbers of minute


    $second = $diff - ($days*86400+$hours*3600+$min*60); //// secondes

    if($days > 0) echo $days." Days ago";
    elseif($hours > 0) echo $hours." Hours ago";
    elseif($min > 0) echo $min." Minute ago";
    else echo "Just second ago";

Something like this?

$day = $start;
while ($day < $end) {
        $day += 86400;
        echo $day.' '.date('Y-m-d', $day).PHP_EOL;
}

By the way, 1262304000 is Dec 31, not Jan 1.

get the difference of two dates and divide it by 86400. abs(($date1 - $date2) / 86400) will produce the needed result
