HomeBackend DevelopmentPHP TutorialPHP中VC6、VC9、TS、NTS版本的区别与用法详解_php技巧

1. VC6与VC9的区别:

VC6版本是使用Visual Studio 6编译器编译的,如果你的PHP是用Apache来架设的,那你就选择VC6版本。

VC9版本是使用Visual Studio 2008编译器编译的,如果你的PHP是用IIS来架设的,那你就选择 VC9版本。

VC9版本是针对IIS服务器的版本,没有对APACHE的支持,而VC6版本对IIS和apache都提供了支持

2.Ts与nts的区别:

Windows版的PHP从版本5.2.1开始有Thread Safe和NoneThread Safe之分。

先从字面意思上理解,Thread Safe是线程安全,执行时会进行线程(Thread)安全检查,以防止有新要求就启动新线程的CGI执行方式而耗尽系统资源。Non Thread Safe是非线程安全,在执行时不进行线程(Thread)安全检查。

3.PHP的两种执行方式:ISAPI和FastCGI。

ISAPI执行方式是以DLL动态库的形式使用,可以在被用户请求后执行,在处理完一个用户请求后不会马上消失,所以需要进行线程安全检查,这样来提高程序的执行效率,所以如果是以ISAPI来执行PHP,建议选择ThreadSafe版本;

而FastCGI执行方式是以单一线程来执行操作,所以不需要进行线程的安全检查,除去线程安全检查的防护反而可以提高执行效率,所以,如果是以FastCGI来执行PHP,建议选择NonThread Safe版本。

通过phpinfo(); 查看其中的 Thread Safety 项,这个项目就是查看是否是线程安全,如果是:enabled,一般来说应该是ts版,否则是nts版。
