PHP has the <a href="http://ca.php.net/rand" rel="noreferrer">rand()</a> function:

<pre><code>$int= rand(1262055681,1262055681);
</code></pre>

It also has <a href="http://ca.php.net/mt_rand" rel="noreferrer">mt_rand()</a>, which is generally purported to have better randomness in the results:

<pre><code>$int= mt_rand(1262055681,1262055681);
</code></pre>

To turn a timestamp into a string, you can use <a href="http://php.net/date" rel="noreferrer">date()</a>, ie:

<pre><code>$string = date("Y-m-d H:i:s",$int);
</code></pre>

You can just use a random number to determine a random date. Get a random number between 0 and number of days between the dates. Then just add that number to the first date.

For example, to get a date a random numbers days between now and 30 days out.

<pre><code>echo date('Y-m-d', strtotime( '+'.mt_rand(0,30).' days'));
</code></pre>

blocks|key|2190038|text|如果给定的日期是日期时间格式，那么使用这个最简单的方法是将两个数字都转换为时间戳，然后将它们设置为随机数生成器上的最小和最大界限。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2190039|一个简单的PHP示例如下：|2190040|//+Find+a+randomDate+between+$start_date+and+$end_date

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:

<pre><code>// 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);
}
</code></pre>

This function makes use of <a href="http://php.net/manual/en/function.strtotime.php">strtotime()</a> 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.

blocks|key|781601|text|另一种使用PHP+DateTime的解决方案|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|781602|$start和$end是DateTime对象，我们将其转换为时间戳。然后，我们使用mt_rand方法来获取它们之间的随机时间戳。最后，我们重新创建一个DateTime对象。|781603|function+randomDateInRange(DateTime+$start,+DateTime+$end)+{

Another solution using PHP <a href="http://php.net/manual/en/class.datetime.php" rel="noreferrer"><code>DateTime</code></a>

<code>$start</code> and <code>$end</code> are <a href="http://php.net/manual/en/class.datetime.php" rel="noreferrer"><code>DateTime</code></a> objects and we convert into Timestamp. Then we use <a href="https://secure.php.net/manual/en/function.mt-rand.php" rel="noreferrer"><code>mt_rand</code></a> method to get a random Timestamp between them. Finally we recreate a <a href="http://php.net/manual/en/class.datetime.php" rel="noreferrer"><code>DateTime</code></a> object.

<pre><code>function randomDateInRange(DateTime $start, DateTime $end) {
 $randomTimestamp = mt_rand($start-&gt;getTimestamp(), $end-&gt;getTimestamp());
 $randomDate = new DateTime();
 $randomDate-&gt;setTimestamp($randomTimestamp);

The amount of <code>strtotime</code> in here is WAY too high. 
For anyone whose interests span before 1971 and after 2038, here's a modern, flexible solution:

<pre><code>function random_date_in_range( $date1, $date2 ){
 if (!is_a($date1, 'DateTime')) {
 $date1 = new DateTime( (ctype_digit((string)$date1) ? '@' : '') . $date1);

 $random_u = random_int($date1-&gt;format('U'), $date2-&gt;format('U'));
 $random_date = new DateTime();
 $random_date-&gt;setTimestamp($random_u);
 return $random_date-&gt;format('Y-m-d') .'&lt;br&gt;';
}
</code></pre>

Call it any number of ways ...

<pre><code>// timestamps
echo random_date_in_range(157766400,1489686923);

// any date string
echo random_date_in_range('1492-01-01','2050-01-01');

// English textual parsing
echo random_date_in_range('last Sunday','now');

// DateTime object
$date1 = new DateTime('1000 years ago');
$date2 = new DateTime('now + 10 months');
echo random_date_in_range($date1, $date2);
</code></pre>

As is, the function requires <code>date1</code> &lt;= <code>date2</code>.

</code></pre>

readers requirements could vary from app to another, in general hope this function is a handy tool where you need to generate some random dates/ sample data for your application.

Please note that the function initially in debug mode, so change it to <code>$mood=""</code> other than debug in production .

The function accepts:

<ol>
<li>start date </li>
<li>end date</li>
<li>format: any php accepted format for date or time</li>
<li>timezone: name or offset number</li>
<li>mode: debug, epoch, verbose epoch or verbose</li>
</ol>

the output in not debug mode is random number according to optional specifications.

tested with PHP 7.x

blocks|key|1957611|text|我们可以使用date_format的另一种解决方案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1957612|+/**

An other solution where we can use date_format :

<pre><code> /**
 * 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);
}
</code></pre>

You could use for example :

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

i had a same situation before and none of the above answers fix my problem so i 

Came with new function

<pre><code>function randomDate($startDate, $endDate, $count = 1 ,$dateFormat = 'Y-m-d H:i:s')
{
 //inspired by
 // https://gist.github.com/samcrosoft/6550473

 // Convert the supplied date to timestamp
 $minDateString = strtotime($startDate);
 $maxDateString = strtotime($endDate);

 if ($minDateString &gt; $maxDateString) 
 {
 throw new Exception("From Date must be lesser than to date", 1);

 }

 for ($ctrlVarb = 1; $ctrlVarb &lt;= $count; $ctrlVarb++) 
 { 
 $randomDate[] = mt_rand($minDateString, $maxDateString); 
 }
 if (sizeof($randomDate) == 1) 
 {
 $randomDate = date($dateFormat, $randomDate[0]);
 return $randomDate;
 }elseif (sizeof($randomDate) &gt; 1) 
 {
 foreach ($randomDate as $randomDateKey =&gt; $randomDateValue) 
 {
 $randomDatearray[] = date($dateFormat, $randomDateValue);
 }
 //return $randomDatearray;
 return array_values(array_unique($randomDatearray));
 }
}
</code></pre>

Now the testing Part(Data may change while testing )

<pre><code>$fromDate = '2012-04-02';
$toDate = '2018-07-02';
</code></pre>

print_r(randomDate($fromDate,$toDate,1));

result will be

<pre><code>2016-01-25 11:43:22
</code></pre>

print_r(randomDate($fromDate,$toDate,1));

<pre><code>array:10 [▼
 0 =&gt; "2015-08-24 18:38:26"
 1 =&gt; "2018-01-13 21:12:59"
 2 =&gt; "2018-06-22 00:18:40"
 3 =&gt; "2016-09-14 02:38:04"
 4 =&gt; "2016-03-29 17:51:30"
 5 =&gt; "2018-03-30 07:28:48"
 6 =&gt; "2018-06-13 17:57:47"
 7 =&gt; "2017-09-24 16:00:40"
 8 =&gt; "2016-12-29 17:32:33"
 9 =&gt; "2013-09-05 02:56:14"
]
</code></pre>

But after the few tests i was thinking about what if the inputs be like

<pre><code>$fromDate ='2018-07-02 09:20:39';
$toDate = '2018-07-02 10:20:39';
</code></pre>

So the duplicates may occur while generating the large number of dates such as <code>10,000</code>

so i have added <code>array_unique</code> and this will return only the non duplicates

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 :

<pre><code>$string = randomdate(1262055681,1262055681);
</code></pre>
