php如何获取表单上传文件的绝对路径
图片：

$src=$_POST['src'];
获取的是 1.jpg
如何获取包含绝对路径的地址，如：D:\php\Essamp\wwwroot\huaxia\Img\1.jpg


------解决方案--------------------
当file改变(onchange时间记录)时候将src给隐藏域赋值，服务端获取该隐藏域就行了
------解决方案--------------------
1 这样做没有意义 将用户的本地路径展示出来会招致反感 
2 如果非要这么做 可以将输入框中的字符串赋值给页面中hidden变量 这样post出去就可以
  给你个参考 js赋给hidden变量你自己实现吧
