访问从JSON转换的数组中对象的键值

Question

I have this JSON string:

"Filters": [
   {"IsActive" : "1"},
   {"Gender" : "M"}
]

That I'm converting into an array $filters. When I var_dump I get:

array(2) {
  [0]=>
  array(1) {
    ["IsActive"]=>
    string(1) "1"
  }
  [1]=>
  array(1) {
    ["Gender"]=>
    string(1) "M"
  }
}

I am trying to access the Key / Value pairs. The Keys are not always Gender, or IsActive. They can be anything, with any value.

 foreach ($filters as $key => $value) {
   echo "
Filter: " . $key . " => " . $value;
 }

But it outputs:

Filter: Array => Array
Notice: Array to string conversion in

Why am I unable to access the k/v pairs?

You are not looking deeply enough at the array. Its actually an array of arrays, so one way to process it would beto use another foreach like this

foreach ($filters as $arr) {
    foreach ($arr as $key => $value) {
        echo "
Filter: " . $key . " => " . $value;
    }
}
