PHP7已经发布了, 作为PHP10年来最大的版本升级, 最大的性能升级, PHP7在多放的测试中都表现出很明显的性能提升, 然而, 为了让它能发挥出最大的性能, 我还是有几件事想提醒下.
代码如下:
opcache.huge_code_pages=1
这样一来, PHP会把自身的text段, 以及内存分配中的huge都采用大内存页来保存, 减少TLB miss, 从而提高性能.
代码如下:
opcache.file_cache=/tmp
这样PHP就会在/tmp目录下Cache一些Opcode的二进制导出文件, 可以跨PHP生命周期存在.
代码如下:
$ make prof-gen
然后用你的项目训练PHP, 比如对于Wordpress:
代码如下:
$ sapi/cgi/php-cgi -T 100 /home/huixinchen/local/www/htdocs/wordpress/index.php >/dev/null
也就是让php-cgi跑100遍wordpress的首页, 从而生成一些在这个过程中的profile信息.
最后:
$ make prof-clean $ make prof-use && make install
这个时候你编译得到的PHP7就是为你的项目量身打造的最高性能的编译版本.
暂时就这么多吧, 以后想起来再加, 欢迎大家尝试, thanks

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
