Question

I am currently converting a ASP.NET C# application to PHP. The service uses DateTime Ticks and I was wondering if there is an equivalent in PHP.

If not what is the best way for me to calculate a timespan?

Answer 1

Use microtime(true)

Please note the following, straight off the PHP manual

By default, microtime() returns a string in the form “msec sec”, where
sec is the current time measured in the number of seconds since the
Unix epoch (0:00:00 January 1, 1970 GMT), and msec is the number of
microseconds that have elapsed since sec 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.
