##PHP 20周年了！？？**PHP 首发通告，1995年6月8日****发布于 COMP.INFOSYSTEMS.WWW.AUTHORING.CGI**        主题：正式宣布：个人主页工具（Personal Home Page Tools）        正式宣布个人主页工具（PHP 工具）1.0 版本        此工具是一组用 C 语言写的轻量的 cgi 二进制文件。他们能运行许多功能，包括：        - 在你的私有日志文件记录页面访问情况    - 实时查看日志信息    - 提供查看日志信息的友好接口    - 在你的页面展示最近一次的访问信息    - 完整的每天及总体访问统计    - 依据用户的域名限制其访问    - 依据用户的域名为页面提供密码保护    - 依据用户的电子邮箱地址追踪其访问情况    - 支持追踪引荐 URL 的 HTTP_REFERER    - 无需服务器支持即可运行 SSI (server-side includes)    - 支持不记录特定域名（比如，你自己的）的访问信息    - 轻易地创建并展示表格    - 支持在后续的文档中使用表格信息        使用该工具，你不需要：        - 你不需要访问根目录??工具安装在 ~/public_html 目录    - 你不需要在服务器启用 SSI (server-side includes)    - 你不需要使用 Perl 或 Tcl 或其他任何脚本解释器    - 你不需要访问 httpd 日志文件            使用该工具的唯一条件是你能够运行自己的 cgi 程序。如果你不知道这是什么意思，可以询问系统管理员。        借助该工具，你还可以在两分钟内实现留言板，或其他任何用于写入信息并向访客展示的表格。        该工具不受版权限制，遵循 GNU 公共许可证。是的！该工具完全免费！        查看该工具的完整演示，请访问：http://www.io.org/~rasmus。        --    Rasmus Lerdorf    rasmus@io.org    http://www.io.org/~rasmus## 用于 Web 应用的 C API    void Cos(void) {    Stack *s;    char temp[64];    s = Pop();    if(!s) {        Error("Stack error in cos");        return;    }    sprintf(temp,"%f",cos(s->douval));    Push(temp,DNUMBER);    }###于是乎，你可以这样使用它：    <html><head><title>Cos Example</title></head>    <body><h1 id="Cos-Example">Cos Example</h1>    <?echo Cos($input)>    </body></html>##PHP7#####? 引擎提升- 现实世界中的大多数应用程序都能获得 100% 以上的性能提升- 内存使用量更低- 原生线程本地储存#####? 持久的以文件为基础的二级缓存 OPCache![](http://talks.php.net/presentations/slides/intro/pcache.png)```    ;
