php - multidimensional array json_decode (first level) -

i have json file this:

{     "numeric1": {         "id": "numeric1",         "name": "alphanumeric1",         "key": "alphanumeric2",         "expire": "alphanumeric3",         "status": true,         "ads": true     },      etc... } 

with (etc...) mean matrix repeated more times. parse php using:

$allowed = json_decode(file_get_contents("allowed.json"), true); 

then array like:

array (     [0] => array         (             [id] => numeric1             [name] => alphanumeric1             [key] => alphanumeric2             [expire] => alphanumeric3             [status] => 1             [ads] => 1         )       etc....  ) 

so lose first level of associative keys, have

 [0] => array

instead of

 ["numeric1"] => array

how can keep first level of json array? thanks.

try this:

$allowed = (array) json_decode(file_get_contents("allowed.json")); 

so instead of directly parsing json array (by specifying second parameter of json_decode), first object preserve key, cast array.
