Question

我正在尝试以这种格式输出JSON：

[{"name":"venue 1"}, {"name":"venue 2"}, {"name":"venue 3"}]

但它目前正是这样出现的：

{"name":"venue 1"}{"name":"venue 2"}{"name":"venue 3"}

这是我的代码：

query = "SELECT * FROM venues";
$result = mysqli_query($con, $query);

while ($row = mysqli_fetch_array($result, MYSQLI_BOTH)) {

    $arr = array(
    'name'=> $row['name']
    );

    print json_encode($arr);

我需要改变什么？

Answer 1

$arr[]代替$arr

while ($row = mysqli_fetch_array($result, MYSQLI_BOTH)) {
 $arr[] = array('name'=> $row['name'] );
}   
echo json_encode($arr);

Answer 2

试试这个：

$arr[] = array(
'name'=> $row['name']
);

Answer 3

Simply make an array like

$array[]["name"]="value1";
$array[]["name"]="value2";
$array[]["name"]="value3";
echo json_encode($array);

you will get the json data as:
[{"name":"value1"},{"name":"value2"},{"name":"value3"}]
which you wants. You have to make the array using looping statements according to your need.

如何以这种方式格式化我的JSON？
