$array=unserialize($serialized);
echo'<pre>';
print_r($array);
echo'</pre>';

You can then access the information like a normal array. For more information see: unserialize

I get this array from database with this query function. $userdata = get_user_meta( $user_id, '_sfwd-data', true) and now i try to unserialize this. $array=unserialize($userdata); echo'<pre>'; print_r($array); echo'</pre>'; but it does not work. It shows nothing.

Please use var_dump($userdata) and show the output above.

Then $userdata does not deliver any result, I am not using Wordpress, so please ensure that your function call of "get_user_meta" is successful and provides data. If this is given, the unerialize will work out proper.

hello @D.Schalla, $userdata works without unserialize function. When i print out the result without serialize, it shows the serialized array.The problem is 'unserialize' i think.

Please use var_dump($userdata); directly under the $userdata=get_user_meta(...) and post the output. If this is false, it cannot work with unserialize. It should provide something different.
