Question

这是我的代码，获取我需要的查询结果

$json_array = array();
$sql = "call rep_info();";
$result = $connect->query($sql);
while ($row = $result->fetch_assoc()) {
  $json_array[] = $row;
}

mysqli_free_result($result);  
mysqli_next_result($connect); 

// Buat info user
$json_array2 = array();
$sql = "call rep_user();";

$result = $connect->query($sql);
while ($row = $result->fetch_assoc()) {
  $json_array2[]["user"] = $row;
}

然后我像这样将两个数组合并为一个

$timeline = array_merge($json_array[0],$json_array2[0]);
$timeline2 = array_merge($json_array[1],$json_array2[1]);

$timeline = array_merge($timeline,$timeline2);

编码合并后的数组以及回显变量

$encoded = json_encode($timeline);

echo $encoded;

所以基本上我想要显示的是查询结果的两行，它们来自json_array [0]和json_array [1]。但是我在json_array [1]和json_array2 [1]的回显结果中只得到1行。

这段代码有什么问题？谢谢！

尝试这样

$timeline = $json_array[0];
$timeline['user'] = $json_array2[0]['user'];
$timeline2 = $json_array[1];
$timeline2['user'] = $json_array2[1]['user'];

$timeline = [$timeline, $timeline2];

$encoded = json_encode($timeline);

echo $encoded;

假设$json_array与$json_array2的长度相同，则可以像这样合并它们

foreach($json_array as $idx => &$item)
{
  $item['user'] = &$json_array2[$idx]['user'];
}
echo json_encode($json_array);

我不确定您为什么不理解这个1行周期。我会尽力解释它。

您有两个长度相同的数组-$json_array和$json_array2。您遍历$json_array中的每个元素，并查看$json_array2中相同的数组索引。当两个数组中都有对应的元素时，只需将第二个数组中的user键复制到第一个数组中即可。

Json_encode一个合并的数组，但只返回1行
