PHP 5.5.0 released.-PHP-Tutorial-php.cn

The PHP development team is proud to announce the immediate availability of PHP 5.5.0. This release includes a large number of new features and bug fixes.

The key features of PHP 5.5.0 include:

20-Jun-2013
Drop support for bison Improved Zend Engine:
Added ARMv7/v8 versions of various Zend arithmetic functions that are implemented using inline assembler
Added systemtap support by enabling systemtap compatible dtrace probes on linux
Optimized access to temporary and compiled VM variables. 8% less memory reads
The VM stacks for passing function arguments and syntaticaly nested calls were merged into a single stack. The stack size needed for op_array execution is calculated at compile time and preallocated at once. As result all the stack push operations don't require checks for stack overflow any more
General improvement:
Added generators and coroutines.
Added "finally" keyword.
Added simplified password hashing API.
Added support for constant array/string dereferencing.
Added Class Name Resolution As Scalar Via "class" Keyword
Added support for using empty() on the result of function calls and other expressions
Added support for non-scalar Iterator keys in foreach
Added support for list in foreach
Core:
Added Zend Opcache extension and enable building it by default.
Added array_column function which returns a column in a multidimensional array
Added boolval()
Added "Z" option to pack/unpack
Added optional second argument for assert() to specify custom message
Added support for changing the process's title in CLI/CLI-Server SAPIs. The implementation is more robust that the proctitle PECL module

回复讨论(解决方案)

其实楼主是来散分的

依然是不支持 xp 和 window2003 么？
那就没什么意思了

明明是“下里巴人”却偏要扮作“阳春白雪”

我觉得很值得注意的是，php5.5里面有100多处贡献都来自咱们中国人！@Laruence http://www.weibo.com/laruence?page=2&pre_page=1&end_id=3592776740088779&end_msign=-1

希望中国在开源领域有越来越多的人参加并贡献力量，我们做的不应该仅仅是跟随技术的脚本，而是创造出计算机技术的道路~~~

个人饭后感慨，见笑！

表示已经用上5.5正式版了

明明是“下里巴人”却偏要扮作“阳春白雪” 大师还有多久升钻呀，，等着给你祝贺哟~~
