關于PHP7.0與PHP5.6下Laravel博客應用性能對比分析詳解

目前我安裝的 Homestead 虛擬機版本是 2.1.8： 該版本 Homestead 上預裝的 PHP 版本是 5.6.15： 我們使用 ab 命令（Apache 提供的性能測驗工具）在該版本中測驗 Laravel 應用（以目前正在講的使用Laravel開發的博客應用為例）性能，我們模擬 10000 次請求，100 個并發進行壓力測驗：

ab -n 10000 -c 100 http://blog.app/

　　

運行結果如下：

這里我們要關注的是紅色加粗的文字，即每秒處理請求數，這是衡量系統性能的關鍵指標，根據系統及硬體配置的差異，資料會有些出入， 現在我們按照“Laravel Homestead 支持 PHP 7 ”這一節所述將 Homestead 中的 PHP 升級到 7.0 版本， 使用 vagrant ssh 登錄到新添加的 homestead-7 虛擬機，查看 PHP 版本資訊是否正確： 此時在瀏覽器中訪問 http://blog.app 會報錯，因為新安裝的 Homestead 資料庫資料為空，需要登錄到虛擬機運行如下命令運行遷移并填充資料：

php artisan migrate 

php artisan db:seed

　　

再次訪問就OK了，好了我們繼續使用同樣的 ab 命令進行壓力測驗：

ab -n 10000 -c 100 http://blog.app/

經過對比，同一個 Laravel 應用在 PHP 7.0 下的性能比 PHP 5.6 提高了54%，這是一個很顯著的性能提升，當然環境不同資料會有所出入，而且還有更大的提升空間，
