将带有方括号的字符串转换为PHP数组

问题描述：

我有一个字符串，值放在方括号中，并用逗号分隔，例如数组字符串:

I have a string, values are in brackets and separated with comma, like array string:

示例:

[[["Name" , "ID"] , [12]] , ["Test" , 78] , 0]

如何将此字符串转换为PHP数组?

How to convert this string to PHP array?

答

这是 JSON 的字符串表示形式数组，请使用json_decode():

That's a JSON string representation of an array, use json_decode():

$array = json_decode($string);    
print_r($array);

收益:

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [0] => Name
                    [1] => ID
                )
            [1] => Array
                (
                    [0] => 12
                )
        )
    [1] => Array
        (
            [0] => Test
            [1] => 78
        )
    [2] => 0
)

如果它具有任何将成为对象的{ }并且在PHP中将其解码为stdClass对象，除非您将true传递给json_decode()以强制使用数组.

If it had any { } that would be an object and decoded as a stdClass object in PHP unless you pass true to json_decode() to force an array.

由于它被构造为一个PHP数组(从PHP 5.4开始)，因此也可以正常工作(不要对不可信的数据使用eval).绝对没有理由这样做，只是为了好玩:

Since it's structured as a PHP array (as of PHP 5.4), this works as well (don't use eval on untrusted data). There is absolutely no reason to do this, it's just for fun:

eval("\$array = $string;");
print_r($array);
