Php cross-domain problem

I use the laravel framework, the apach environment built by xampp,
header ("content-type:application:json;charset=utf8"); 

    header("Access-Control-Allow-Origin:*");
    header("Access-Control-Allow-Methods:POST");
    header("Access-Control-Allow-Headers:x-requested-with,content-type");

I added such a header header to the php code, but it didn"t work.
ask for advice!

PHP is OK to write in this way, but it may not necessarily be a cross-domain problem. Check out the other files

which file is added specifically? Can the code be more detailed

Why not change the php of the js server since it is php,?

replace * in the code with the actual requester address. Referer Information 

  
 found the problem. The problem lies in the laravel framework, where header ('Access-Control-Allow-Origin:*'); is cross-domain in the native PHP language. You need to use the cors cross-domain plug-in in laravel
