How to Get Current Time in Milliseconds in PHP

Get current timestamp with milliseconds

It can print less digits, because it is a float value. So if you get 1234.0005, that `.0005 actually means 500 microseconds. The zeroes after the 5 are lost because it's still an unformatted float value.

The function microtime is based on the system call gettimeofday(), which also isn't accurate to the microsecond. Commonly it's accurate to 10 microseconds. See also Linux - Is gettimeofday() guaranteed to be of microsecond resolution.

-edit- I see the specs in your question have changed from microseconds to milliseconds.

To get the float value you have as an integer, you can multiply by a value. The float value represents seconds. Multiply by 1000 to get milliseconds or 1,000,000 to get microseconds. Since the specs (now) say milliseconds, you should multiply by 1000. 10k will give you accuracy of 1/10ms = 100μs. A millisecond is one thousandth of a second. A microsecond is one millionth of a seconds.

Long story short, to get the time in integer milliseconds, use this:

$milliseconds = intval(microtime(true) * 1000);

Note: there is a reason why you get the time as a string or a float by default. The reason is that on 32 bit systems, PHP's integer is also 32 bits and is not large enough to contain the timestamp including milliseconds and microseconds. So this solution will only work well on a 64 bit system.

Datetime to Timestamp in milliseconds in PHP

Pretty self explanatory code, so I wont say much.

date_default_timezone_set('Australia/Sydney'); // set timezone
$yourdate = '2016-03-22 14:30';
$stamp = strtotime($yourdate); // get unix timestamp
$time_in_ms = $stamp*1000;

If you want to display it properly.

echo number_format($time_in_ms, 0, '.', '');

Getting date format m-d-Y H:i:s.u from milliseconds

php.net says:

Microseconds (added in PHP 5.2.2). Note that date() will always generate 000000 since it takes an integer parameter, whereas DateTime::format() does support microseconds if DateTime was created with microseconds.

So use as simple:

$micro_date = microtime();
$date_array = explode(" ",$micro_date);
$date = date("Y-m-d H:i:s",$date_array[1]);
echo "Date: $date:" . $date_array[0]."<br>";

Recommended and use dateTime() class from referenced:

$t = microtime(true);
$micro = sprintf("%06d",($t - floor($t)) * 1000000);
$d = new DateTime( date('Y-m-d H:i:s.'.$micro, $t) );

print $d->format("Y-m-d H:i:s.u"); // note at point on "u"

Note u is microseconds (1 seconds = 1000000 µs).

Another example from php.net:

$d2=new DateTime("2012-07-08 11:14:15.889342");

Reference of dateTime() on php.net

I've answered on question as short and simplify to author. Please see for more information to author: getting date format m-d-Y H:i:s.u from milliseconds

Date to milliseconds in PHP

I've tried this date("YmdHisu") but it returns time to microseconds.

If you don't need the microseconds then just strip them:

substr(date("YmdHisu"), 0, -3);

But, because currently date() formats the value returned by time() that doesn't contain fractions of seconds, the result will always end with 000 (no milliseconds available).

You can get the date and the milliseconds as you need if you use date("YmdHis") to format the date and time part (whole seconds) and extract and concatenate the first 3 digits of the microseconds part returned by microtime():

echo(date("YmdHis").substr(microtime(FALSE), 2, 3));

PHP - get milliSecond from Timestamp

You can use microtime (which is better solution because you will get exact value).

Getting unix timestamp in milliseconds in PHP5 and Actionscript3

For actionscript3, new Date().getTime() should work.

In PHP you can simply call time() to get the time passed since January 1 1970 00:00:00 GMT in seconds. If you want milliseconds just do (time()*1000).

If you use microtime() multiply the second part with 1000 to get milliseconds. Multiply the first part with 1000 to get the milliseconds and round that. Then add the two numbers together. Voilá.

converting milliseconds to amount of time string

PHP has a date function which do what you want:

date("H:i:s", '183547165');

It outputs:

09:19:25

How to convert time in milliseconds in php

$string = "00:38:42,689";
$time   = explode(":", $string);

$hour   = $time[0] * 60 * 60 * 1000;
$minute = $time[1] * 60 * 1000;

$second = explode(",", $time[2]);
$sec    = $second[0] * 1000;
$milisec= $second[1];

$result = $hour + $minute + $sec + $milisec;

echo $result;
