如何将PHP数组编码为JSON数组而不是对象? [英] How do I encode a PHP array to a JSON array, not object?
问题描述
我正在尝试对Zend_DB查询返回的数组进行json_encode.
I am trying to json_encode an array which is returned from a Zend_DB query.
var_dump给出:(手动添加0个成员不会更改图片.)
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"
}
}
编码后的字符串如下:
{"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文档应该是什么样子.
Which is what the php.ini/json_encode documentation says it should look like.
推荐答案
如何设置初始数组?
如果您将其设置为:
array(
"1" => array(...),
"2" => array(...),
);
那么您就没有一个带有数字索引而是一个字符串的数组,并且该数组将转换为JS world中的一个对象.如果您未设置严格的顺序(即从0开始而不是1),也会发生这种情况.
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).
但是,这是在黑暗中拍摄的,因为我看不到您的原始代码:首先尝试完全不使用键来设置数组:
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(...),
);
