将会话值附加到 API 请求 php 的现有数组结构中

Question

我正在使用一个 API，其中对 API 的每个请求都应该重新发送所有以前的值。我将所有以前的值存储在 php 会话中。生成的数组结构将被 json_encoded 并用于 Curl 请求。除了在现有问题上附加新问题外，一切正常。以下是代码：

$question_counter = ++$_SESSION['question_counter'];
$questionidnew = strip_tags($_POST['questionid1']);
$answernew = strip_tags($_POST['answer1']);
//store new questions as session array
$_SESSION['questions'][$question_counter] = array(
    'questionid' => $questionidnew,
    'questionanswer' => $answernew,
    );
$question_array[] = $_SESSION['questions'];//previous questions

print_r($question_array); 给出以下结果：

Array ( [0] => Array ( 
[1] => Array ( [questionid] => p_48 [questionanswer] => absent ) 
[2] => Array ( [questionid] => p_122 [questionanswer] => absent ) 
) )

如何将其附加到现有数据结构的格式：

$to_json = [
  'sex' => $gender,
  'age' => $age,
  'evidence' => [
    ['id' => $test_id1, 'choice_id' => 'present', 'initial' => true],
    ['id' => $test_id2, 'choice_id' => 'present', 'initial' => true],
    ['id' => $questionidnew, 'choice_id' => $answernew],
    ['id' => 'p_12', 'choice_id' => $choice, 'initial' => true],
    ['id' => $location, 'choice_id' => 'present', 'initial' => true]
  ],
  'extras' => [
    'disable_users' => true
  ],
];

由于我是一名新手程序员，我遇到了一些错误，并且发现为会话中的先前问题添加以下内容有点令人困惑：

['id' => $questionidnew, 'choice_id' => $answernew], 

请求帮助。

如果我没看错，您想将所有新答案添加到 $to_json 数组，对吗？我最终做了以下事情来实现这一点。我冒昧，可能有误解，所以如果这没有帮助，请纠正我：

<?php
session_start();
if(!isset($_SESSION['question_counter'])) {
  $_SESSION['question_counter'] = 0;
}

$gender = "male";
$age = 46;
$test_id1 = 12;
$test_id2 = 24;
$questionidnew = 9;
$answernew = "B";
$choice = "A";
$location = "campus";

$to_json = array(
  'sex' => $gender,
  'age' => $age,
  'evidence' => array(
    array('id' => $test_id1, 'choice_id' => 'present', 'initial' => true),
    array('id' => $test_id2, 'choice_id' => 'present', 'initial' => true),
    array('id' => $questionidnew, 'choice_id' => $answernew),
    array('id' => 'p_12', 'choice_id' => $choice, 'initial' => true),
    array('id' => $location, 'choice_id' => 'present', 'initial' => true)
  ),
  'extras' => array(
    'disable_users' => true
  ),
);

$question_counter = ++$_SESSION['question_counter'];
//$questionidnew = strip_tags($_POST['questionid1']);
//$answernew = strip_tags($_POST['answer1']);
//store new questions as session array
$_SESSION['questions'][$question_counter] = array(
    'questionid' => $questionidnew,
    'questionanswer' => $answernew,
    );
$question_array[] = $_SESSION['questions'];//previous questions

echo "<pre>";
print_r($to_json);
echo "</pre>";
//$_SESSION['names'][] = $name;

foreach($question_array as $question) {
  foreach($question as $key => $value) {
    $to_json['evidence'][] = array('id' => $value['questionid'], 'choice_id' => $value['questionanswer']);
  }
}
echo "<pre>";
print_r($to_json);
echo "</pre>";
print_r(json_encode($to_json));
?>
