Default function values

[JasonDFR]

What is the best way to assign default arguments to function variables when the default is taken from the value of another function.

Example:

function function($startDate = time()) {

echo $startDate;

}

function(); 

I would like to do the above, but it does not work.

Do you have to test for $startDate inside the function and then set it to time() if it is null? Or is there a better way?

Thanks.

This is usually the best way to do it:

function function($startDate = null) {
  $startDate = is_null($startDate) ? time():$startDate;
}

Cool. Thanks.
