Question

我试图解析从MySQL数据库中提取的json字符串。 json字符串包含一个二维数组，但json_decode返回null，json_last_error返回0，我认为这意味着没有发生错误。

$ result是json字符串

json_decode($result, true);

字符串：

[
 ["17544500374","17544500489","17544500571","17544500587","17544500528"],
 ["17544500651","17544500432","17544500673","17544500452","17544500362"],
 ["17544500454","17544500457","17544500523","17544500441"],
 ["17544500547","17544500463","17544500535","17544500676"],
 ["17544500548","17544500581","17544500584","17544500382"],
 ["17544500593","17544500364","17544500660","17544500595"],
 ["17544500635","17544500647","17544500529","17544500670"]
]

Answer 1

您的值没有密钥。这意味着，您的第二个参数不正确，因为该函数无法创建关联数组。

这适用于我的mashine：

json_decode($result);

Answer 2

$result必须是字符串：

$result = '[["17544500374","17544500489","17544500571","17544500587","17544500528"],["17544500651","17544500432","17544500673","17544500452","17544500362"],["17544500454","17544500457","17544500523","17544500441"],["17544500547","17544500463","17544500535","17544500676"],["17544500548","17544500581","17544500584","17544500382"],["17544500593","17544500364","17544500660","17544500595"],["17544500635","17544500647","17544500529","17544500670"]]'

PHP用json解析多维数组
