我试图从我的数据库中获取一个JSON字符串，但数据库返回多行数据，当JSON编码时，不适合使用正确的格式 .
我目前的PHP代码
$conn = [omitted];
$sql = [omitted];
$result = $conn->query($sql); //this query has been proven to work
if ($result->num_rows > 0) {
$rows = [];
while($row = $result->fetch_assoc()) {
$row[] = array_merge($row,$rows);
}
echo json_encode($rows);
} else {
echo "0";
}
但是这个代码在与 $row 数组合并之前回显了 $rows 数组 .
目前的结果：
[]
通缉结果：
[{"id":"1","team_name":"[omitted]","has_finished":"0"},{"id":"2","team_name":"[omitted]","has_finished":"0"},{"id":"3","team_name":"[omitted]","has_finished":"0"},{"id":"4","team_name":"[omitted]","has_finished":"0"},{"id":"5","team_name":"[omitted]","has_finished":"0"},{"id":"6","team_name":"[omitted]","has_finished":"0"},{"id":"7","team_name":"[omitted]","has_finished":"0"}]

您永远不会将任何数据分配到$ rows数组中 . 要将每一行分配到数组中，您需要将其作为循环 .
