1.前端页面
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

2.php页面


<"Token"];//输出Token
var_dump($arr);//输出整个数组
function get_getallheaders() //定义方法
{ 
 foreach ($_SERVER as $name => $value) //循环_SERVER数组
 { 
 if (substr($name, 0, 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
} 


3.php页面返回的headers


array(11) {
 ["Cookie"]=>
 string(94) "Hm_lvt_f62fa14829605f0d29c05da9c30e045a=1503649309,1503884728; _ga=GA1.1.1091059248.1504832863"
