As other have stated  you can use microtime   to get millisecond precision on timestamps   From your comments  you seem to want it as a high-precision UNIX Timestamp  Something like DateTime Now Ticks in the  NET world   You may use the following function to do so   function millitime        microtime   microtime       comps   explode       microtime         Note  Using a string here to prevent loss of precision      in case of  overflow   PHP converts it to a double    return sprintf   d 03d    comps 1    comps 0    1000

try this   public function getTimeToMicroseconds          t   microtime true        micro   sprintf   06d     t - floor  t     1000000        d   new DateTime date  Y-m-d H i s      micro   t         return  d- gt format  Y-m-d H i s u

Use microtime  This function returns a string separated by a space  The first part is the fractional part of seconds  the second part is the integral part  Pass in true to get as a number   var dump microtime              string 21   0 89115400 1283846202  var dump microtime true         float 1283846202 89    Beware of precision loss if you use microtime true    There is also gettimeofday that returns the microseconds part as an integer   var dump gettimeofday        array 4        sec    gt    int 1283846202      usec    gt    int 891199      minuteswest    gt    int -60      dsttime    gt    int 1

Use microtime true  in PHP 5  or the following modification in PHP 4   array sum explode      microtime        A portable way to write that code would be   function getMicrotime         if  version compare PHP VERSION   5 0 0     lt                   return array sum explode      microtime                 return microtime true

timeparts   explode     microtime      currenttime   bcadd   timeparts 0  1000  bcmul  timeparts 1  1000    echo  currenttime       NOTE  PHP5 is required for this function due to the improvements with   microtime   and the bc math module is also required  as we   re dealing   with large numbers  you can check if you have the module in phpinfo     Hope this help you

This works even if you are on 32-bit PHP   list  msec   sec    explode      microtime       time milli    sec substr  msec  2  3       1491536422147   time micro    sec substr  msec  2  6       1491536422147300    Note this doesn t give you integers  but strings  However this works fine in many cases  for example when building URLs for REST requests    If you need integers  64-bit PHP is mandatory   Then you can reuse the above code and cast to  int    list  msec   sec    explode      microtime         these parentheses are mandatory otherwise the precedence is wrong                                                  time milli    int    sec substr  msec  2  3       1491536422147  time micro    int    sec substr  msec  2  6       1491536422147300   Or you can use the good ol  one-liners    time milli    int  round microtime true    1000         1491536422147  time micro    int  round microtime true    1000000      1491536422147300

Short answer  64 bits platforms only  function milliseconds          mt   explode      microtime         return   int  mt 1     1000     int round  mt 0    1000         If you are running 64 bits PHP then the constant PHP INT SIZE equals to 8    Long answer  If you want an equilvalent function of time   in milliseconds first you have to consider that as time   returns the number of seconds elapsed since the  quot epoch time quot   01 01 1970   the number of milliseconds since the  quot epoch time quot  is a big number and doesn t fit into a 32 bits integer  The size of an integer in PHP can be 32 or 64 bits depending on platform  From http   php net manual en language types integer php  The size of an integer is platform-dependent  although a maximum value of about two billion is the usual value  that s 32 bits signed   64-bit platforms usually have a maximum value of about 9E18  except for Windows  which is always 32 bit  PHP does not support unsigned integers  Integer size can be determined using the constant PHP INT SIZE  and maximum value using the constant PHP INT MAX since PHP 4 4 0 and PHP 5 0 5   If you have 64 bits integers then you may use the following function  function milliseconds          mt   explode      microtime         return   int  mt 1     1000     int round  mt 0    1000       microtime   returns the number of seconds since the  quot epoch time quot  with precision up to microseconds with two numbers separated by space  like    0 90441300 1409263371  The second number is the seconds  integer  while the first one is the decimal part  The above function milliseconds   takes the integer part multiplied by 1000 1409263371000  then adds the decimal part multiplied by 1000 and rounded to 0 decimals 1409263371904  Note that both  mt 1  and the result of round are casted to int  This is necessary because they are floats and the operation on them without casting would result in the function returning a float  Finally  that function is slightly more precise than round microtime true  1000    that with a ratio of 1 10  approx   returns 1 more millisecond than the correct result  This is due to the limited precision of the float type  microtime true  returns a float   Anyway if you still prefer the shorter round microtime true  1000   I would suggest casting to int the result   Even if it s beyond the scope of the question it s worth mentioning that if your platform supports 64 bits integers then you can also get the current time in microseconds without incurring in overflow  If fact 2 63 - 1  biggest signed integer  divided by 10 6   3600   24   365  approximately the microseconds in one year  gives 292471  That s the same value you get with echo  int   PHP INT MAX     1000000   3600   24   365       In other words  a signed 64 bits integer have room to store a timespan of over 200 000 years measured in microseconds  You may have then function microseconds          mt   explode      microtime         return   int  mt 1     1000000     int round  mt 0    1000000
