How do I include array from another PHP file

Question

In the handle_signup.php page, I try to handle with the data which was sent from the sign up page. If the nickname blank has no value, then the error message is "Please enter your nickname". So, in the signup page, I try to include the $errorMsgs array from handle_signup.php page and show the msg below the nickname input. How can I get the array from the handle_signup.php page? Currently, I use include_once, but there is no message in the array after transferring to handle_signup.php. Could some one help this issue? Thank you.

Handle the value from signup.php

<?php
  require_once('./conn.php');
  $errorMsgs = array('nickname'=>'', 'email'=>'', 'password'=>'');


  if(isset($_POST['submit'])) {
    if(empty($_POST['nickname'])) {
      $errorMsgs['nickname'] = "Please enter your nickname";
      header("Location: ./signup.php");
    }
  };
?>

Sign up page - signup.php

<?php
  include_once 'handle_signup.php';
  var_dump($errorMsgs);
?>

正如 DarkBee 所建议的，您可以使用$_SESSION来显示错误消息，或者干脆不使用header("Location: ./signup.php")而是将所有 PHP 代码包含在同一页面中。
