ajax接收到的字符串长度不一样问题
我用ajax传递一个参数，然后php接收，用var_dump打印出来，长度是41，然后我把同样的字符串拷贝到php，直接var_dump打印出来，长度是42.如下：

string(41) "
[data]"
string(42) "
[data]"

字符串是一样的，长度不一样，不知道为何会造成如此差别，考虑到可能编码不一样，尝试过
接收的时候声明编码，如
header("Content-type: text/html; charset=GB2312");
获取把字符串统一转成一样的编码，都未解决问题。
请问这种情况最有可能的原因是什么？

------解决方案--------------------
这是操作系统引起的差异
window 系统是回车换行(\r\n)
linux 系统是换行(\n)

正好差一个字符
------解决方案--------------------
print_r(unpack('H*', $str));
看一下就知道了！
瞎猜有什么用？
