This looks like an excellent beginning so thanks. A few general comments:
1) I notice that your book is "© Copyright 2013, Julien Pauli -
Anthony Ferrara - Nikita Popov. All Rights Reserved" rather than GDFL
or one of the CC variants of open document licences. They only issue
that I see here is that I -- and possibly others -- might be a bit
guarded in providing comment and input if that content was being
transferred to the authors unconditionally. Also if you are reserving
all rights then you will need to be careful to ensure that all the
content is yours and not extracted from an open or other 3rd party
source. Surely this going to add to your authoring burden?
2) Wikipedia, for example, contains a lot of good in-depth explanation
of CompSci concepts and standard patterns such as
http://en.wikipedia.org/wiki/Hash_table. You might consider the content
cut: when you include basic discussion of 101 principles (e.g. on
HashTables); and when you limit
your content to their PHP-specific implementation, with suitable
references to the 101 stuff. Tending to the former will make the book a
lot longer, albeit standalone. Your call, but I would have thought that
the majority of the readership by nature will have some CompSci
background and so want to skip the 101 stuff, or be referenced out to
the appropriate in-depth WP or other reference.
3) What is your preferred markup format for feedback and contributions?
E.g. do you maintain an ODF or Docbook XML under some accessible git
repository, or is is a case of (for example)
hashtables/basic_structure.html para at line 138. Not quite true that
"the arBucket array will never shrink down: you can not reduce a PHP
array, you only can grow it". You can always implement your own
resizer by realloing the arBucket array and the calling
zend_hash_rehash() to do this. (This would be a good standard hash
API function by the way.
But good luck and this will be an extremely useful project to help those
wishing to get to grips with PHP internals.

Terry
