   多数情况下,基于JavaScript 的Js框架如jquery、Mootools、Prototype等,在发出Ajax请求指令时,都会发送额外的 HTTP_X_REQUESTED_WITH 头部信息,就当是一个ajax请求,因此你可以在服务器端检测到这些Ajax请求,在PHP中的检测方法如下代码所示:

  1

  2if(!emptyempty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) =='xmlhttprequest'){

  3 //这里面是你的ajax请求处理逻辑

  4}else{

  5 //一些逻辑。。。

  6}

  7?>

  在开发Ajax交互应用时候用得到。
