是否将数组值转换为类属性资源密集型？

Question

I have an array with approximately 50 keys & values. I would like to take the array and create class properties from the values like so:

$arr = array();
$arr['name'] = 'John';
$arr['age'] = '20';

$object = (object) $arr;

echo $object->name;

My question is, is this very resource-intensive? Would it require a lot of overhead with a large array? If so, would there be a better way of doing this?

Also, this does not work if the array is setup like:

$arr = array();
$arr['name']['boy'] = 'John';
$arr['name']['girl'] = 'Jane';
$arr['age']['boy'] = '20';
$arr['age']['girl'] = '30';

$object = (object) $arr;

echo $object->name->boy;

Answer 1

You can make like this :

$arr = array();

$arr['name']['boy'] = 'John';
$arr['name']['girl'] = 'Jane';
$arr['age']['boy'] = '20';
$arr['age']['girl'] = '30';


$obj = json_decode(json_encode($arr)); //Turn it into an object


print_r($obj);    // to view the result

echo $obj->name->boy;   // output: John

It works great with simple arrays and with subarrays too.

I think this is good solution when we work with subarrays and we want to save resources
