How get a detail of an array result

Question

I don't know how to do this in PHP so I i'll ask it here. Right now I have this:

$s3 = $sdk->getUser();
var_dump($s3["custom_fields"]);

It results in:

string(51) "a:1:{s:3:"IGN";s:27:"hfsdkklsdhfasfhoihgoiahgoid";}"

The only thing I want is: hfsdkklsdhfasfhoihgoiahgoid

How can I get that?

Answer 1

it's a serialized array.

var_dump(unserialize($s3["custom_fields"]));

there ya go.

Answer 2

You can do it this way:

$s3 = $sdk->getUser();
$custom_fields = unserialize($s3["custom_fields"]);

echo $custom_fields['IGN'];
