Return current Unix timestamp with microseconds
&reftitle.description;
mixedmicrotime
boolget_as_floatfalse
microtime returns the current Unix timestamp with
microseconds. This function is only available on operating systems that
support the gettimeofday() system call.
&reftitle.parameters;
get_as_float
If used and set to &true;, microtime will return a
float instead of a string, as described in
the return values section below.
&reftitle.returnvalues;
By default, microtime returns a string in
the form "msec sec", where sec is the number of seconds
since the Unix epoch (0:00:00 January 1,1970 GMT), and msec
measures microseconds that have elapsed since sec
and is also expressed in seconds.
If get_as_float is set to &true;, then
microtime returns a float, which
represents the current time in seconds since the Unix epoch accurate to the
nearest microsecond.
