1.前端页面
2.PHP页面
$value) //循环_SERVER数组
{
if (substr($name,5) == 'HTTP_') //前5个字符是HTTP_的进入循环
{
$headers[str_replace(' ','-',ucwords(strtolower(str_replace('_',' ',substr($name,5)))))] = $value;
//注释
//substr($name,5)，从$name第5个字符向后截取
//str_replace('_',)下划线替换成空格
//strtolower()全部转换为小写
//ucwords()首字母转换为大写
//str_replace(' ',)所有空格替换为-
}
}
return $headers; //返回前key前5个字符是HTTP_的数组
//return $_SERVER; //返回_SERVER数组
}
