PHP 5.3 And PHP 6 A Look Ahead
- 1. What is new in PHP 5.3? Stefan Priebsch, e-novative GmbH
- 2. Disclaimer
- 3. First Plans for PHP 6 Paris Developer Meeting Derick's Meeting Minutes www.php.net/~derick/meeting-notes.html First Release Candidate late 2006
- 4. First Plans for PHP 6 Paris Developer Meeting Derick's Meeting Minutes www.php.net/~derick/meeting-notes.html First Release Candidate late 2007
- 5. First Plans for PHP 6 Paris Developer Meeting Derick's Meeting Minutes www.php.net/~derick/meeting-notes.html First Release Candidate ... some day
- 6. And PHP 6 ...
- 7. ... became PHP 5.3 ...
- 8. ... almost
- 9. Unicode
- 10. Unicode One Standard to rule them all PHP 6's killer feature One character != one byte
- 12. Garbage Collection Free memory while script is running gc_enable(); gc_disable();
- 13. SPL Improvements
- 14. SPL Improvements SplDoublyLinkedList SPLStack SPLQueue SplPriorityQueue
- 15. SPL Stack $stack = new SplStack(); $stack->push('a'); $stack->push('b'); $stack->push('c'); echo $stack->pop(); echo $stack->pop(); echo $stack->pop();
- 16. SPL Stack $stack = new SplStack(); $stack->push('a'); $stack->push('b'); $stack->push('c'); echo $stack->pop(); echo $stack->pop(); echo $stack->pop(); -> cba
- 18. Magic Calls class Foo { public function __call($aName, $aParameters) { var_dump($aName); var_dump($aParameters); } } $foo = new Foo(); $foo->test('something');
- 19. Magic Calls class Foo { public function __call($aName, $aParameters) { var_dump($aName); var_dump($aParameters); } } $foo = new Foo(); $foo->test('something'); -> string(4) "test" array(1) { [0]=> string(9) "something" }
- 20. Magic Calls Strict standards: Non-static method Foo::test() should not be called statically
- 21. Magic Static Calls class Foo { public static function __callStatic($aName, $aParameters) { ... } } Foo::doSomething(...);
- 23. Late Static Binding class Foo { protected static $foo = 'Test'; public static function getFoo() { return self::$foo; } } var_dump(Foo::getFoo());
- 24. Late Static Binding class Foo { protected static $foo = 'Test'; public static function getFoo() { return self::$foo; } } var_dump(Foo::getFoo()); -> Test
- 25. Late Static Binding class Foo { protected static $foo = 'Test'; public static function getFoo() { return self::$foo; } } class MyFoo extends Foo { protected static $foo = 'MyTest'; } var_dump(Foo::getFoo()); var_dump(MyFoo::getFoo());
- 26. Late Static Binding class Foo { protected static $foo = 'Test'; public static function getFoo() { return self::$foo; } } class MyFoo extends Foo { protected static $foo = 'MyTest'; } var_dump(Foo::getFoo()); var_dump(MyFoo::getFoo()); -> string(4) "Test" string(4) "Test"
- 27. Late Static Binding class Foo { protected static $foo = 'Test'; public static function getFoo() { return static::$foo; } } class MyFoo extends Foo { protected static $foo = 'MyTest'; } var_dump(Foo::getFoo()); var_dump(MyFoo::getFoo());
- 28. Late Static Binding class Foo { protected static $foo = 'Test'; public static function getFoo() { return static::$foo; } } class MyFoo extends Foo { protected static $foo = 'MyTest'; } var_dump(Foo::getFoo()); var_dump(MyFoo::getFoo()); -> string(4) "Test" string(6) "MyTest"
- 29. Namespaces
- 30. class File { ... } Namespaces
- 31. class File { ... } // somewhere else class File { ... } Namespaces
- 32. class my_Web_Framework_Foo_Bar_Baz { ... } Namespaces
- 33. namespace my::Web::Framework::Foo::Bar; class Baz { ... } Namespaces
- 34. namespace my::Web::Framework::Foo::Bar; class Baz { ... } // somewhere else: $baz = new my::Web::Framework::Foo::Bar::Baz(); Namespaces
- 35. use my::Web::Framework::Foo::Bar::Baz as MyBaz; $baz = new myBaz(); Namespaces
- 36. namespace crypt; function gnupg_decrypt($aText, $aKeyFile) { return 'some plaintext'; } Namespaces
- 37. namespace crypt; function gnupg_decrypt($aText, $aKeyFile) { return 'some plaintext'; } var_dump(gnupg_decrypt('sa45hzq734hrq243rwaefsd80', 'my.key')); Namespaces
- 38. namespace foo; class bar { static public function baz() { return 'baz method'; } } var_dump(foo::bar::baz()); Namespaces
- 39. namespace foo; class bar { static public function baz() { return 'baz method'; } } var_dump(foo::bar::baz()); -> string(10) "baz method" Namespaces
- 40. namespace foo::bar; function baz() { return 'baz function'; } namespace foo; class bar { static public function baz() { return 'baz method'; } } var_dump(foo::bar::baz()); Namespaces
- 41. Namespaces Access built-in functions/classes by prefixing :: some_fn(...) vs. ::some_fn(...) __NAMESPACE__ constant Multiple namespaces per file
- 42. More New Features ifsetor OpenID support SQLite3 getopt() works on Windows __DIR__ = dirname(__FILE__)
- 43. Error Handling
- 44. Error Handling New error class E_DEPRECATED E_ALL includes E_STRICT
- 45. Future-Proofing
- 46. Regular Expressions ereg will move to PECL replace ereg_* by preg_* by the way, ereg is not binary safe
- 47. Deprecated php.ini Settings short open tags magic quotes register_globals register_long_arrays ze1.compatibility_mode allow_call_time_pass_reference safe_mode
- 51. Thank you.
