Question

我有一个var_dump($array)生成

的数组

array(7) 
    { 
    ["*attributes"]=> array(4) 
    { 
        ["type"]=> string(6) "hidden" 
        ["name"]=> string(3) "hmo" 
        ["class"]=> string(12) "form-control" 
        ["id"]=> string(3) "hmo" 
    } 
    ["*label"]=> NULL 
    ["*labelAttributes"]=> array(0) { } 
    ["*labelOptions"]=> array(0) { } 
    ["*messages"]=> array(0) { } 
    ["*options"]=> array(1) 
    { 
        ["disable_inarray_validator"]=> bool(true) 
    } 
    ["*value"]=> string(243) "{"My-Office":{"Floor":"New - ","Walls":"New - ","Door":"New - ","Switches":"New - ","Table":"New - ","Chair":"New - "},"Other office":{"Floor":"New - ","Walls":"New - ","Door":"New - ","Switches":"New - ","Table":"New - ","Chair":"New - "}}" 
   }

我正在尝试访问最后一个位置的json字符串（* value）但我无法使用$array['*value']访问它，因为我什么都没有返回。如果我var_dump($array['*value'])我得到NULL。有谁知道为什么$array['*value']没有给我我需要的字符串？

使用

array_values(array_slice($array, -1))[0];

访问数组$ array的最后一个元素。

无法在关联数组中获取值
