Is there a standard way to indicate what the associative keys of a parameter that is passed in should be in phpDocumentor

For example

 * @param array $an_Array An开发者_JAVA技巧 array of stuff that is needed.
                an_associate_key Description about this key.
                another_key Another Description.

No, there is no way to get it parsed by phpDocumentor. The only way (you mentioend it yourself) is to describe it in the parameters' description.

As a side note: phPDocumentor seems to be not really maintained anymore. You may have a look at DocBlox and write a feature request in its issue tracker
