PHP5.4新特性
PHP5.4新特性
PHP5.4正式前两天发布了，之前有看了一些PHP5.4主要特性相关文章，因此在这里小结一下。
其中好几点更新是由Laruence贡献的！本文部分内容也是源自Laruence的博客。
1. Buid-in web server
PHP5.4内置了一个简单的Web服务器，这样在做一些简单程序就方便多了，省去了环境配置的工作，特别对于初学者来说。
把当前目录作为Root Document只需要这条命令即可:
$ php -S localhost:3300
也可以指定其它路径：
$ php -S localhost:3300 -t
/path/to/root
还可以指定路由：
$ php -S localhost:3300 router.php
参考：PHP: Build-in web server
Traits提供了一种灵活的代码重用机制，即不像interface一样只能定义方法但不能实现，又不能像class一样只能单继承。至于在实践中怎样使用，还需要深入思考。
官网的一个例子：
trait SayWorld {
&&&&&&&&public
function sayHello() {
&&&&&&&&&&&&&&&&parent::sayHello();
&&&&&&&&&&&&&&&&echo
&World!n&;
&&&&&&&&&&&&&&&&echo
'ID:' . $this-&id .
&&&&&&&&public
function sayHello() {
&&&&&&&&&&&&&&&&echo
MyHelloWorld extends
&&&&&&&&private
&&&&&&&&public
function __construct() {
&&&&&&&&&&&&&&&&$this-&id = 123456;
&&&&&&&&use
= new MyHelloWorld();
$o-&sayHello();
参考：http://cn.php.net/manual/en/language.oop5.traits.php
3. Short array syntax
PHP5.4提供了数组简短语法：
= [1,'james',
4. Array dereferencing
myfunc() {
&&&&return
array(1,'james',
我认为比数组简短语法更方便的是dereferencing，以前我们需要这样：
= myfunc();
echo $arr[1];
在PHP5.4中这样就行了：
myfunc()[1];
5. Upload progress
Session提供了上传进度支持，通过$_SESSION[&upload_progress_name&]就可以获得当前文件上传的进度信息，结合Ajax就能很容易实现上传进度条了。
参考：//2217.html
6. JsonSerializable Interface
实现了JsonSerializable接口的类的实例在json_encode序列化的之前会调用jsonSerialize方法，而不是直接序列化对象的属性。
参考：//2204.html
7. Use mysqlnd by default
现在mysql, mysqli, pdo_mysql默认使用mysqlnd本地库，在PHP5.4以前需要:
$./configure
--with-mysqli=mysqlnd
$./configure
--with-mysqli

. Replaced zend_function.return_reference by ZEND_ACC_RETURN_REFERENCE
in zend_function.fn_flags.
. Removed zend_arg_info.required_num_args as it was only needed for internal
functions. Now the first arg_info for internal functions (which has special
meaning) is represented by zend_internal_function_info structure.
. Moved zend_op_array.size, size_var, size_literal, current_brk_cont,
backpatch_count into CG(context) as they are used only during compilation.
. Moved zend_op_array.start_op into EG(start_op) as it's used only for
'interactive' execution of single top-level op-array.
. Replaced zend_op_array.done_pass_two by ZEND_ACC_DONE_PASS_TWO in
zend_op_array.fn_flags.
. op_array.vars array is trimmed (reallocated) during pass_two.
. Replaced zend_class_entry.constants_updated by ZEND_ACC_CONSTANTS_UPDATED
in zend_class_entry.ce_flags.
. Reduced the size of zend_class_entry by sharing the same memory space
by different information for internal and user classes.
See zend_ union.
. Reduced size of temp_variable.
- Changed the structure of op_array.opcodes. The constant values are moved from
opcode operands into a separate literal table. (Dmitry)
- Improved Zend Engine, performance tweaks and optimizations: (Dmitry)
. Inlined most probable code-paths for arithmetic operations directly into
. Eliminated unnecessary iterations during request startup/shutdown.
. Changed $GLOBALS into a JIT autoglobal, so it's initialized only if used.
(this may affect opcode caches!)
. Improved performance of @ (silence) operator.
. Simplified string offset reading. $str[1][0] is now a legal construct.
. Added caches to eliminate repeatable run-time bindings of functions,
classes, constants, methods and properties.
. Added concept of interned strings. All strings constants known at compile
time are allocated in a single copy and never changed.
. Added an optimization which saves memory and emalloc/efree calls for empty
HashTables. (Stas, Dmitry)
. ZEND_RECV now always has IS_CV as its result.
. ZEND_CATCH now has to be used only with constant class names.
. ZEND_FETCH_DIM_? may fetch array and dimension operands in different order.
. Simplified ZEND_FETCH_*_R operations. They can't be used with the
EXT_TYPE_UNUSED flag any more. This is a very rare and useless case.
ZEND_FREE might be required after them instead.
. Split ZEND_RETURN into two new instructions ZEND_RETURN and
ZEND_RETURN_BY_REF.
. Optimized access to global constants using values with pre-calculated
hash_values from the literals table.
. Optimized access to static properties using executor specialization.
A constant class name may be used as a direct operand of ZEND_FETCH_*
instruction without previous ZEND_FETCH_CLASS.
. zend_stack and zend_ptr_stack allocation is delayed until actual usage.
- Improved CLI SAPI: (Johannes, Moriyoshi)
. Added command line option --rz &name& which shows information of the
named Zend extension. (Johannes)
. Interactive readline shell improvements: (Johannes)
. Added &cli.pager& php.ini setting to set a pager for output.
. Added &cli.prompt& php.ini setting to configure the shell prompt.
. Added shortcut #inisetting=value to change ini settings at run-time.
. Changed shell not to terminate on fatal errors.
. Interactive shell works with shared readline extension. FR #53878.
- Improved FastCGI SAPI: (Dmitry)
. Added apache compatible functions: apache_child_terminate(),
getallheaders(), apache_request_headers() and apache_response_headers()
. Improved performance of FastCGI request parsing.
- Improved core functions:
. number_format() no longer truncates multibyte decimal points and thousand
separators to the first byte. FR #53457. (Adam)
. Added hex2bin() function. (Scott)
- Improved CURL extension:
. Added support for CURLOPT_MAX_RECV_SPEED_LARGE and
CURLOPT_MAX_SEND_SPEED_LARGE. FR #51815. (Pierrick)
- Improved Date extension:
. Added the + modifier to parseFromFormat to allow trailing text in the
string to parse without throwing an error. (Stas, Derick)
- Improved DBA extension:
. Added Tokyo Cabinet abstract DB support. (Michael Maclean)
. Added Berkeley DB 5 support. (Johannes, Chris Jones)
- Improved filesystem functions:
. scandir() now accepts SCANDIR_SORT_NONE as a possible sorting_order value.
FR #53407. (Adam)
- Improved HASH extension:

. Added new json_encode() option JSON_UNESCAPED_SLASHES. FR #49366. (Adam)
- Improved LDAP extension:
. Added paged results support. FR #42060. (ando@OpenLDAP.org,
iarenuno@eteo.mondragon.edu, jeanseb@au-fil-du.net, remy.)

Swift是Apple在WWDC2014所发布的一门编程语言，用来撰写OS X和iOS应用程序[1]。在设计Swift时．就有意和Objective-C共存，Objective-C是Apple操作系统在导入Swift前使用的编程语言
Swift是供iOS和OS X应用编程的新编程语言，基于C和Objective-C，而却没有C的一些兼容约束。Swift采用了安全的编程模式和添加现代的功能来使得编程更加简单、灵活和有趣。界面则基于广受人民群众爱戴的Cocoa和Cocoa Touch框架，展示了软件开发的新方向。
PHP（外文名:PHP: Hypertext Preprocessor，中文名：“超文本预处理器”）是一种通用开源脚本语言。语法吸收了C语言、Java和Perl的特点，利于学习，使用广泛，主要适用于Web开发领域。PHP 独特的语法混合了C、Java、Perl以及PHP自创的语法。它可以比CGI或者Perl更快速地执行动态网页。用PHP做出的动态页面与其他的编程语言相比，PHP是将程序嵌入到HTML（标准通用标记语言下的一个应用）文档中去执行，执行效率比完全生成HTML标记的CGI要高许多；PHP还可以执行编译后代码，编译可以达到加密和优化代码运行，使代码运行更快。
