使用 PHP 7 给 Web 应用加速
PHP 20周年了!??
PHP 首發通告,1995年6月8日
發布于 COMP.INFOSYSTEMS.WWW.AUTHORING.CGI
主題:正式宣布:個人主頁工具(Personal Home Page Tools)正式宣布個人主頁工具(PHP 工具)1.0 版本此工具是一組用 C 語言寫的輕量的 cgi 二進制文件。他們能運行許多功能,包括:在你的私有日志文件記錄頁面訪問情況
實時查看日志信息
提供查看日志信息的友好接口
在你的頁面展示最近一次的訪問信息
完整的每天及總體訪問統計
依據用戶的域名限制其訪問
依據用戶的域名為頁面提供密碼保護
依據用戶的電子郵箱地址追蹤其訪問情況
支持追蹤引薦 URL 的 HTTP_REFERER
無需服務器支持即可運行 SSI (server-side includes)
支持不記錄特定域名(比如,你自己的)的訪問信息
輕易地創建并展示表格
-
支持在后續的文檔中使用表格信息
使用該工具,你不需要:
你不需要訪問根目錄——工具安裝在 ~/public_html 目錄
你不需要在服務器啟用 SSI (server-side includes)
你不需要使用 Perl 或 Tcl 或其他任何腳本解釋器
-
你不需要訪問 httpd 日志文件
使用該工具的唯一條件是你能夠運行自己的 cgi 程序。如果你不知道這是什么意思,可以詢問系統管理員。
借助該工具,你還可以在兩分鐘內實現留言板,或其他任何用于寫入信息并向訪客展示的表格。
該工具不受版權限制,遵循 GNU 公共許可證。是的!該工具完全免費!
查看該工具的完整演示,請訪問:http://www.io.org/~rasmus。

用于 Web 應用的 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,你可以這樣使用它:
<html><head><title>Cos Example</title></head> <body><h1>Cos Example</h1> <?echo Cos($input)> </body></html>PHP7
? 引擎提升
現實世界中的大多數應用程序都能獲得 100% 以上的性能提升
內存使用量更低
原生線程本地儲存
? 持久的以文件為基礎的二級緩存 OPCache

安裝 Vagrant 與 Virtualbox
之后:
$ git clone https://github.com/rlerdorf/php7dev.git$ cd php7dev$ vagrant up ... (takes a bit - it is downloading 1.5G)$ vagrant ssh它會 NAT, DHCP 并產生固定的地址 192.168.7.7
http://192.168.7.7/ 會展示 PHP 7 的 phpinfo() 頁面。
現在,你的開發環境就部署好啦。
切換 PHP 版本比較繁雜:
