听说nginx不需要多个进程, 那不是多个请求都用同一个进程, 不会干扰么?

php代码需要改写么?

完全不需要，跟php没有任何关系，php是个脚本语言，自己有虚拟机处理这些东西，你完全不需要关心在什么平台运行

不是完全没影响 有些变量如_SERVER[PHP_SELF]与是apache还是nginx有关系的

使用PHP，可以说你只需要关注PHP解释器便可以了，无论是结合哪个web server，都需要调用解释器来执行脚本的。

不仅不会干扰...相反这种单进程（线程）的模型在高并发下性能会更好...比如nodejs...
因为高并发下..多进程（线程）模型会使CPU的计算能力大部分浪费在其进程（线程）切换上...

$_SERVER 变量可能会有影响 然后重写规则需要修改 别的 基本上差不多
