經過WEB服務器來實現PHP多線程功能。php
固然,對多線程有深刻理解的人都知道經過WEB服務器實現的多線程只能模仿多線程的一些效果,並非真正意義上的多線程。web
但無論怎麼樣,它仍是能知足咱們的一些須要的,在須要相似多線程的功能方面仍是能夠採用這個類。服務器

使用方法:多線程
$thread = new thread(); $thread->addthread('func1','info1'); $thread->addthread('func2','info2'); $thread->addthread('func3','info3'); $thread->runthread();函數
說明:ui
addthread是添加線程函數,第一個參數是函數名,以後的參數(可選)爲傳遞給指定函數的參數。this
runthread是執行線程的函數。spa
