Description:
------------
Strval documentation is unclear on whether it works on objects.

Parameter documentation for val:
var may be any scalar type. You cannot use strval() on arrays or objects.

Example #1:
echo strval(new StrValTest);

Does not compute.

Please explain what else needs to be said in the Parameters section regarding the $var parameter which currently reads:

"The variable that is being converted to a string.

var may be any scalar type. You cannot use strval() on arrays or objects."

Clearly, new StrValTest which returns an object of class StrValTest, is an object and can't be used by strval().

It isn't bogus. The example contradicts the parameter description. It can take objects iff they implement the __toString() method.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
