$string = "00:00:11";
$time   = explode(":", $string);

$hour   = $time[0] * 60 * 60 * 1000;
$minute = $time[1] * 60 * 1000;
$sec    = $time[2] * 1000;

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

echo $result;

$time = '11:22:33';    
$seconds = strtotime("1970-01-01 $time UTC");
$miliseconds = $seconds * 1000;

echo $seconds ."\n" . $miliseconds;

output: 40953 40953000

I think OP wants milliseconds not seconds. – bansi Mar 01 '17 at 06:30

Date to time conversion will be like as follows


    $Given_date   = date('H:i:s');

    $hour         = date('H',strtotime($Given_date));
    $minute       = date('i',strtotime($Given_date));
    $seconds      = date('s',strtotime($Given_date));

    $sec_to_milli = $seconds * 1000;            //seconds to milliseconds
    $min_to_milli = $minute * 60 * 1000;        //minutes to milliseconds
    $hrs_to_milli = $hour * 60 * 60 * 1000;     //hours to milliseconds

    $milliseconds = $hrs_to_milli + $min_to_milli + $sec_to_milli;

    echo $milliseconds;

Hh: mm: SS to milliseconds
