我的数据库中有多个表,我想将它们连接在一起以为GET请求创建嵌套的JSON。有一次我想基于数据库中的值添加一个数组,例如(类型===“ fixValue”)。
... $sql = "SELECT name, type
FROM section INNER JOIN question ON section.section_id = question.section_id
WHERE question.section_id = ".$row_section['section_id']."";
$stmtq = $db->query($sqlq);
$stmtq -> execute();
while( $row_question = $stmtq->fetch(PDO::FETCH_ASSOC)){
$question_array['name'] = $row_question['name'];
$question_array['type'] = $row_question['type'];
if($row_question['type'] == "fixValue"){
$question_array['options'] = array();
}
array_push($section_array['sectionQuestion'], $question_array);
} ....
我的json输出现在是:
{
"name": "Test",
"something": "Test",
"array1": [
{
"name": "Section",
"array2": [
{
"name": "Something",
"type": "fixValue",
"options": []
},
{
"name": "Sometthing2",
"type": "notFixValue",
"options": []
}
]
}
]}
我想要的输出:
{
"name": "Test",
"something": "Test",
"array1": [
{
"name": "Section",
"array2": [
{
"name": "Something",
"type": "fixValue",
"options": []
},
{
"name": "Sometthing2",
"type": "notFixValue",
}
]
}
]}
因此,不仅将options数组添加到值为“ fixValue”的项。具有不同类型值(如“ fixValue”)的项目应没有“ options”数组。 有任何想法如何实现这样的目标吗?

尝试使用counter而不是array_push:
... $sql = "SELECT name, type
FROM section INNER JOIN question ON section.section_id = question.section_id
WHERE question.section_id = ".$row_section['section_id']."";
$stmtq = $db->query($sqlq);
$stmtq -> execute();
$cnt = 0;
while( $row_question = $stmtq->fetch(PDO::FETCH_ASSOC)){
$question_array['name'] = $row_question['name'];
$question_array['type'] = $row_question['type'];
if($row_question['type'] == "fixValue"){
$question_array['options'] = array();
}
$section_array['sectionQuestion'][$cnt] = $question_array;
unset($question_array);
$cnt++;
} ....
