Rookie problem: Phpstorm the built-in server running post is invalid

Purpose: Two numbers added, sent to the server with post, but the server did not receive the submission
First, post.html




Add





Second, post_server.php

Print_r ($_post);
if ($_post[' a '] && $_post[' B ']) {
Echo $_post[' A ']+$_post[' B '];
}else{
The echo ' parameter cannot be empty! ';
};

Third, the operation result:
Array ()
notice:undefined index:a in E:\xampp\htdocs\tools\post_server.php on line 11
None of the parameters are empty!

Iv. Other Notes
Using the built-in server http://localhost:63342/htdocs/tools/post.html
But use Apache to run no problem http://localhos/tools/post.html
Phpstorm version 10.0.1
PHP Interpreter settings: E:\xampp\php\php.exe
The built-in server needs to be configured?

Who told you to use Phpstorm 10, return 9 on the line.
