我的函数有两个函数。php

这两个函数都来自一个插件，我试图在另一个操作中使用这个变量$answerIndex来执行if条件。

问题是我正在尝试全局变量，但它不起作用，我是否做错了什么？

add_action(\'quiz_completed\', \'mi_ld_quiz_ert\', 10, 2);
function mi_ld_quiz_ert( $quizdata, $current_user ) {
global $globalres;
    if($globalres== 0){
        do_action(\'ld_update_group_access\', $current_user, 2, $remove = false ));
    }else{
        do_action(\'ld_update_group_access\', $current_user, 14, $remove = false ));
    }
}

add_action(\'learndash_ques_single_answer_correct\', \'my_ld_quiz_resp\',5,5);
function my_ld_quiz_resp(  $answerIndex, $correctAnswer, $userResponse) {
  global $globalres;
  $globalres = $answerIndex; 
}

首先运行操作my\\u ld\\u quick\\u resp，然后运行mi\\u ld\\u quick\\u ert。

$globalres = \'\';

add_action(\'quiz_completed\', \'mi_ld_quiz_ert\', 10, 2);
function mi_ld_quiz_ert( $quizdata, $current_user ) {
  global $globalres;
  if($globalres== 0){
    do_action(\'ld_update_group_access\', $current_user, 2, $remove = false     ));
  }
  else{
    do_action(\'ld_update_group_access\', $current_user, 14, $remove = false ));
   }
}

add_action(\'learndash_ques_single_answer_correct\', \'my_ld_quiz_resp\',5,5);
function my_ld_quiz_resp(  $answerIndex, $correctAnswer, $userResponse) {
  global $globalres;
  $globalres = $answerIndex; 
}
