如何在数组中获取逗号分隔符（，）值？

Question

这是我的数组，即$ data。

function generateQuestion($userdata) {
$module_name = $userdata->module_name;
$module = new Module();
$module->data['*'] = '';
$module->where = " module_name = '" . $module_name . "' and is_delete='0'";
$module->action = "get";
$module_res = $module->process();
$data = array();
if($module_res['count'] > 0) {
    foreach ($module_res['res'] as $module_key => $module_value) {
        $cat = new Category();
        $cat->data['*'] = '';
        $cat->where = "que_module_id='".$module_value['module_id']."' and is_delete='0'";
        $cat->action = "get";
        $cat_res = $cat->process();

        foreach ($cat_res['res'] as $cat_key => $cat_value) {
            $question = new Question();
            $question->data['*'] = '';
            $question->where = "question_cat_id='".$cat_value['que_cat_id']."' and is_delete='0'";
            $question->action = "get";
            $question_res = $question->process();
            foreach ($question_res['res'] as $question_key => $question_value) {
                $que_ans = '';
                if($question_value['question_ans'] == 1) {
                    $que_ans = 'Yes';
                } elseif($question_value['question_ans'] == 2) {
                    $que_ans = 'No';
                } else {
                    $que_ans = 'N/A';
                }
                $options = explode(',',$question_value['question_options']);

                $data[$module_value['module_name']][$cat_value['que_cat_id']][$question_value['question_id']] = array(
                    'question_name' => $question_value['question_name'],
                    'question_ans'  => $que_ans,
                    'question_ans_comments' => $question_value['question_ans_comments'] == ''?'None':$question_value['question_ans_comments'],
                    'question_options' => explode(',',$question_value['question_options'])
                );
            }
        }
    }
    print_r($data);die;
    //echo json_encode(array("data"=>$data,"status" => "success", 'message' => 'Question Listing'));
} else {
    echo json_encode(array("status" => "error", 'message' => 'Module Not Found'));
}
}
  $data[$module_value['module_name']][$cat_value['que_cat_id']]
 [$question_value['question_id']] = array(
                    'question_name' => $question_value['question_name'],
                    'question_ans'  => $que_ans,
                    'question_ans_comments' => $question_value['question_ans_comments'] == ''?'None':$question_value['question_ans_comments'],
                    'question_options' => explode(',',$question_value['question_options'])
                );

以上数组的输出：

    (
        [3] => Array
            (
                [1] => Array

我的数据库字段存储question_options，如1,2,3,4

我希望数组像

请帮我解决这个问题。

Answer 1

试试这个。

$options = array(1,2,4); // array of explode(',',$question_value['question_options'])

    function getOptions($options){
        $temparray = array();
        $option_fix_array = array(
                    1 => 'Yes',
                    2 => 'NO',
                    3 => 'N/A',
                    4 => 'Comments', 
                );
        foreach($options as $value){
            if(array_key_exists($value,$option_fix_array)){
                $temparray[$value] = $option_fix_array[$value];
            }
        }
        return $temparray;
    }

    print_r(getOptions($options));

我认为这会帮助你。

Answer 2

声明一个数组如下：

$meaningArray = array(
    1 => 'Yes',
    2 => 'No',
    3 => 'N/A',
    4 => 'Comment'
);

并使用：

'question_options' => explode(',',$meaningArray[$question_value['question_options']]);

而不是：

'question_options' => explode(',',$question_value['question_options'])
