php:array()和{}之间的区别 [英] php: different between array( ) and { }

问题描述

Array
    (
        [user_id] => 1
        [username] => user
        [first_name] => hello
        [last_name] => world
    )

和

{
    user_id: "1",
    username:"user",
    first_name:"hello",
    last_name:"world"
}

?以及如何在php中转换它们?

? and how to convert them in php?

添加详细信息

实际上，我正在使用redis zunionstore和zrevrange来组合用户数据.结果返回给我类似的东西:

Actually i'm using redis zunionstore and zrevrange to combine user data. The result returns me something like :

Array
(
    [0] =>{"user_id":"1","username":"user","first_name:hello","last_name:world"}
    [1] => ...
)

因为我必须处理数据，所以我想要这样的东西:

Since i have to process the data, i want something like this:

Array
(
    [0] => Array
        (
            [user_id] => 1
            [username] => user
            [first_name] => hello
            [last_name] => world
        )
 ...
)

那么有什么简单的方法可以转换它，而不是使用for循环对每个元素进行json_decode?谢谢

So is there any easy way to convert it instead of using for loop to json_decode each element? Thx

推荐答案

第一个字符串是 print_r 函数的输出.示例:

The first string is the output of the print_r function. Example:

$array=array('key'=>'value');
print_r($array);

输出:

Array
(
    [key] => value
)

您的第二个是类似于JSON的，而且还缺少密钥的双引号.
您不能直接将其转换.

Your second is JSON-like, alto it lacks of double-quotes for keys.
You can't convert them directly.

如果第二个字符串是这样的，则可以使用 json_decode 将JSON转换为PHP数组:

You could convert JSON to a PHP array with json_decode if your second string was something like this:

{
    "user_id": "1",
    "username":"user"
    ...
}
