    Release Manager for 5.5/5.6 PHP Contributor Wrote a book on

    PHP performance Works on a book on PHP internals h﬙p:/ /www.phpinternalsbook.com/ Julien Pauli Performance guy at

    What extensions can do  Extensions can :  Add

    new functions  Add new classes / interfaces  Add and manage php.ini se﬙ings and phpinfo() output  Add new global variables or constants  Add new stream wrappers/filters, new resource ﬚pes  Overwrite what other extensions defined  Extensions cannot :  Modi﬌ PHP syntax  Change the engine executor behavior (zend_extension can)
  34. 95.

    Why create an extension?  Bundle an external library code

    into PHP  Example h﬙ps:/ /github.com/nicolasff/phpredis  Optimize performances  C is way faster than PHP  Create your own C structures and manage them by providing PHP functions  Create your own resource intensive algorithms  Example : h﬙ps:/ /github.com/phadej/igbinary
  35. 96.

    C vs PHP  Don't try to turn the world

    to C  Why you should use PHP over C  C is way more difficult to develop than PHP  C is very less maintainable  C can be tricky to debug  Why you should use C over PHP  Bundle an external lib into PHP (cant be done in PHP)  Looking for speed and fast algos  Changing PHP behavior deeply
  36. 97.

    PHP Objects internals  What you see from PHP land

    is just a "default implementation" in the engine  The ZendEngine 2 (PHP 5) has been designed with a highly extensible object model $o = new MyObject; $o->anAttribute; $o->aMethodCall();
  37. 98.

    PHP Objects internals  An object is a zend_object 

    A class is a zend_class_entry typedef struct _zend_object { zend_class_entry *ce; HashTable *properties; zval **properties_table; HashTable *guards; /* protects from __get/__set ... recursion */ } zend_object;
  38. 99.

    PHP Object handlers  Handlers define objects behaviors struct _zend_object_handlers

    { zend_object_add_ref_t add_ref; zend_object_del_ref_t del_ref; zend_object_clone_obj_t clone_obj; zend_object_read_property_t read_property; zend_object_write_property_t write_property; zend_object_read_dimension_t read_dimension; zend_object_write_dimension_t write_dimension; zend_object_has_property_t has_property; zend_object_unset_property_t unset_property; zend_object_has_dimension_t has_dimension; zend_object_unset_dimension_t unset_dimension; zend_object_get_properties_t get_properties; zend_object_get_method_t get_method; zend_object_call_method_t call_method; zend_object_get_constructor_t get_constructor; zend_object_get_class_entry_t get_class_entry; ...
  39. 100.

    PHP default object handlers  Default handlers exist  They

    define the default PHP behavior you all know  For example, the default "read_dimension" handler  Check's if the object class implements ArrayAccess  Calls for OffsetGet()  Returns what OffsetGet() returned
  40. 101.

    Changing object handlers  By redefining these handlers, one can

     Directly fetch information instead of calling a PHP function to do so  Create special storage and fetchers for a﬙ributes  Change the way objects are stored and retrieved from the engine  This is what has been done in the C version of Pimple
