[PHP-DOC] bool/boolean and int/integer

[Damien Seguy]

Hi,

I noticed that docs are using sometimes bool, sometimes boolean to
describe boolean values. Save for integer and int.

It seems that most frequent occurences are "int" and "bool". Is that
a general rule? I suggest we could harmonize all of this, with only
one expression. 

What do you think?
