get millisecond timestamp in PHP,


Answers ( 1 )


    To answer your question, there are multiple ways to get a millisecond timestamp in PHP. Here are some common methods:

    1. Using microtime() Function

    The microtime() function in PHP is used to return the current Unix timestamp with microseconds. By default, this function returns a string in "msec sec" format, where sec is the current time measured in the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT), and msec is the microseconds part.

    To get the timestamp in milliseconds, you can use the following code:

    list($usec, $sec) = explode(" ", microtime());
    $milliseconds = round(((float)$usec + (float)$sec) * 1000);
    echo $milliseconds;

    2. Using DateTime Class

    PHP's DateTime class provides a more object-oriented way to deal with dates and times. You can use it along with DateTime::format to get the current time in milliseconds:

    $dt = new DateTime();
    $milliseconds = $dt->format('Uv'); // U is for seconds since the epoch, v is for milliseconds
    echo $milliseconds;

    3. Using round() with microtime(true)

    A more straightforward way is to use microtime(true), which returns the current Unix timestamp with microseconds as a float. You can then multiply this by 1000 and use round() to get the timestamp in milliseconds:

    $milliseconds = round(microtime(true) * 1000);
    echo $milliseconds;


    • The microtime() function is the most common and straightforward approach.
    • The DateTime class provides a more object-oriented solution.
    • Using round() with microtime(true) is a concise way to achieve the same result.

    Each method has its own use case, and the choice depends on your specific requirements and coding style preferences in PHP.
