問題描述

我正在嘗試對從 Zend_DB 查詢返回的數組進行 json_encode.

I am trying to json_encode an array which is returned from a Zend_DB query.

var_dump 給出:(手動添加 0 個成員不會改變圖片.)

var_dump gives: (Manually adding 0 member does not change the picture.)

array(3) {
  [1]=>
  array(3) {
    ["comment_id"]=>
    string(1) "1"
    ["erasable"]=>
    string(1) "1"
    ["comment"]=>
    string(6) "test 1"
  }
  [2]=>
  array(3) {
    ["comment_id"]=>
    string(1) "2"
    ["erasable"]=>
    string(1) "1"
    ["comment"]=>
    string(6) "test 1"
  }
  [3]=>
  array(3) {
    ["comment_id"]=>
    string(1) "3"
    ["erasable"]=>
    string(1) "1"
    ["comment"]=>
    string(6) "jhghjg"
  }
}

編碼后的字符串如下所示:

The encoded string looks like:

{"1":{"comment_id":"1","erasable":"1","comment":"test 1"},
 "2":{"comment_id":"2","erasable":"1","comment":"test 1"},
 "3":{"comment_id":"3","erasable":"1","comment":"jhghjg"}}

我需要的是:

[{"comment_id":"1","erasable":"1","comment":"test 1"},
{"comment_id":"2","erasable":"1","comment":"test 1"},
{"comment_id":"3","erasable":"1","comment":"jhghjg"}]

php.ini/json_encode 文檔說它應該是什么樣子.

Which is what the php.ini/json_encode documentation says it should look like.

您如何設置初始數組?

如果你這樣設置:

array(
 "1" => array(...),
 "2" => array(...),
);

那么你沒有一個帶有數字索引的數組，而是字符串，在 JS 世界中它被轉換為一個對象.如果您沒有設置嚴格的順序(即從 0 而不是 1 開始)，也會發生這種情況.

then you don't have an array with numeric indexes but strings, and that's converted to an object in JS world. This can happen also if you don't set a strict order (i.e. starting at 0 instead of 1).

然而，這是在黑暗中拍攝，因為我看不到您的原始代碼:首先嘗試在不使用鍵的情況下設置您的數組:

This is a shot in the dark, however, because I can't see your original code: try setting your array without using keys at all in the first place:

array(
 array(...),
 array(...),
);
