Complete PHP Date Reference

Definition and Usage

The microtime() function returns the current Unix timestamp with microseconds.

Syntax

microtime(get_as_float)

Tips and Notes

Note: This function returns the string "microsec sec", where sec is the number of seconds since the Unix Epoch (0:00:00 January 1, 1970 GMT), and microsec is the microseconds part. Notice that both parts are returned in units of seconds.

Note: The get_as_float parameter was added to PHP 5!

Example

<?php
echo(microtime());
?>

The output of the code above could be:

0.25139300 1138197510
