对象类型数组元素php

Question

I stored some values in db using json_encode .Now on fetching i got values like this ["ab","cd"] .I have tried by exploding , json_encode and then decode.But nothing works.some of tried code is below

$array = "["ab","cd"]";
$value = (array)$array;

//-------------
$array = (array) $array;
// get_object_vars
$array = get_object_vars($object);
print_r($array);

when i loop directly on array i didn't get any values.Thanks for any help in advance. on this i got like this :

var_dump(json_decode($object));
print_r($object);

OUTPUT :

NULL ["MKD","KD3"]

If I am understanding your question, I think you are looking for json_decode .

$json_encoded_str = '["ab","cd"]';

// Will return an array of elements in your string  
var_dump(json_decode($json_encoded_str));

The result would be

array(2) {
    [0]=> string(2) "ab"
    [1]=> string(2) "cd"
}
