다음은 PHP에서 ajax 헤더를 얻는 방법에 대한 예를 공유할 것입니다. 이는 좋은 참고 가치가 있으며 모든 사람에게 도움이 되기를 바랍니다. 함께 살펴볼까요

<?php
$arr = get_getallheaders();//获取http头数组
//echo $arr["Token"];//输出Token
var_dump($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) == &#39;HTTP_&#39;) //前5个字符是HTTP_的进入循环
 { 
 $headers[str_replace(&#39; &#39;, &#39;-&#39;, ucwords(strtolower(str_replace(&#39;_&#39;, &#39; &#39;, substr($name, 5)))))] = $value; 
 //注释
 //substr($name, 5)，从$name第5个字符向后截取
 //str_replace(&#39;_&#39;, &#39; &#39;,)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(&#39; &#39;, &#39;-&#39;,)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
}
