Description:
------------
The type signatures for methods are misleading. All values of $offset 
could also be of type integer, and in the case of offsetSet, the $offset 
could also be null, as is standard in normal PHP array push notation: 
(e.g., $array[] = 'new value';). Since these methods are similar to 
__get() and __set(), which are guaranteed to receive a string as their 
first param, it is important to clearly indicated that the type for 
ArrayAccess methods is string|int.

In addition, the type of the $value parameter for offsetSet should be 
mixed.

Reproduce code:
---------------
---
From manual page: class.arrayaccess

Log: Corrected parameter type hints for ArrayAccess methods. Closes bug #49807

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.

The offsets have been type hinted as "mixed" since the ArrayAccess interface does not restrict the values that can be used for them. For example, one could pass a boolean, object, resource, etc. not just integer, string or null.  It is up to the class implementing the interface to determine what it wants to allow.  Thanks again for your documentation bug report.
