Converting json to array with recursive method?

Question

I am trying to convert json string inside an array into array, ``` $config = array( "type" => '{"category":"admin","page":"page"}', "say" => "Hello", "php" => array( "say" => "no", "type" => '{"category":"admin","page":"page"}', "gran" =>array( "name" => "Hi" ) ) ); ``` My working code, ``` class objectify { public function json_to_array($array, $recursive = true) { # if $array is not an array, let's make it array with one value of former $array. if (!is_array($array)) $array = array($array); foreach($array as $key => $value) { if($recursive === false) $array[$key] = (!empty($value) && is_string($value) && json_decode($value) != NULL) ? json_decode($value, true): $value; else $array[$key] = (!empty($value) && is_string($value) && json_decode($value) != NULL) ? json_decode($value, true): is_array($value) ? self::json_to_array($array) : $value; } return $array; } } ``` It works fine without recursive method but breaks when I want to do the recursive as you can see in my code above, ```…

Quick solution:

```
$full_array = array_map('json_decode', $array);
```

If not all your parameters are JSON, and you want actual arrays instead of `stdClass` objects, you may have to do this:

```
function json_decode_array($input) { 
  $from_json =  json_decode($input, true);  
  return $from_json ? $from_json : $input; 
}
$full_array = array_map('json_decode_array', $array);
```

If you have more levels of nested arrays outside of the JSON, then you have to do your own recursion. Try this version of objectify:

```
class objectify
{
  public function json_mapper($value, $recursive = true) {
    if (!empty($value) && is_string($value) &&
        $decoded = json_decode($value, true)) {
      return $decoded;
    } elseif (is_array($value) && $recursive) {
      return array_map('objectify::json_mapper', $value);
    } else {
      return $value;
    }
  }

// currying, anyone?
  public function json_mapper_norecurse($value) { 
     return objectify::json_mapper($value, false);
  }

public function json_to_array($array, $recursive = true)
  {
    # if $array is not an array, let's make it array with one value of
    # former $array.
    if (!is_array($array)) {
      $array = array($array);
    }

return array_map(
      $recursive ? 'objectify::json_mapper' 
                 : 'objectify::json_mapper_norecurse', $array);
  }
}
```

Which works fine for me on both of your sets of sample data.
