Laruence and I wrote articles about ZendMM internals.
You would find them at http://www.laruence.com/2011/11/09/2277.html
and
http://julien-pauli.developpez.com/tutoriels/php/internals/zend-memory-manager/
.
You can use any translator to get them in English
For basic use, see the readme at
http://lxr.php.net/xref/PHP_5_4/Zend/README.ZEND_MM
Hope this helps :)
