How to generate random date between two dates usin

Question

I am coding an application where i need to assign random date between two fixed timestamps

how i can achieve this using php i've searched first but only found the answer for Java not php

for example :

$string = randomdate(1262055681,1262055681);

Answer 1

The best way :

$timestamp = rand( strtotime("Jan 01 2015"), strtotime("Nov 01 2016") );
$random_Date = date("d.m.Y", $timestamp );

Answer 2

By using carbon and php rand between two dates

$startDate = Carbon::now();
$endDate   = Carbon::now()->subDays(7);

$randomDate = Carbon::createFromTimestamp(rand($endDate->timestamp, $startDate->timestamp))->format('Y-m-d');

OR

$randomDate = Carbon::now()->subDays(rand(0, 7))->format('Y-m-d');

Answer 3

PHP has the rand() function:

$int= rand(1262055681,1262055681);

It also has mt_rand(), which is generally purported to have better randomness in the results:

$int= mt_rand(1262055681,1262055681);

To turn a timestamp into a string, you can use date(), ie:

$string = date("Y-m-d H:i:s",$int);

Answer 4

If given dates are in date time format then use this easiest way of doing this is to convert both numbers to timestamps, then set these as the minimum and maximum bounds on a random number generator.

A quick PHP example would be:

// Find a randomDate between $start_date and $end_date
function randomDate($start_date, $end_date)
{
    // Convert to timetamps
    $min = strtotime($start_date);
    $max = strtotime($end_date);

    // Generate random number using above bounds
    $val = rand($min, $max);

    // Convert back to desired date format
    return date('Y-m-d H:i:s', $val);
}

This function makes use of strtotime() as suggested by zombat to convert a datetime description into a Unix timestamp, and date() to make a valid date out of the random timestamp which has been generated.

Answer 5

An other solution where we can use date_format :

 /**
 * Method to generate random date between two dates
 * @param $sStartDate
 * @param $sEndDate
 * @param string $sFormat
 * @return bool|string
 */

function randomDate($sStartDate, $sEndDate, $sFormat = 'Y-m-d H:i:s') {
    // Convert the supplied date to timestamp
    $fMin = strtotime($sStartDate);
    $fMax = strtotime($sEndDate);
    // Generate a random number from the start and end dates
    $fVal = mt_rand($fMin, $fMax);
    // Convert back to the specified date format
    return date($sFormat, $fVal);
}

You could use for example :

$date_random = randomDate('2018-07-09 00:00:00','2018-08-27 00:00:00');

Answer 6

$yeni_tarih = date('Y-m-d', strtotime( '+'.mt_rand(-90,0).' days'))." ".date('H', strtotime( '+'.mt_rand(0,24).' hours')).":".rand(1,59).":".rand(1,59);
