Best Solution for me:

$output_array = unserialize(My_checker($serialized_string));

code:

function My_checker($serialized_string){
    // securities
    if (empty($serialized_string))                      return '';
    if ( !preg_match('/^[aOs]:/', $serialized_string) ) return $serialized_string;
    if ( @unserialize($serialized_string) !== false ) return $serialized_string;

    return
    preg_replace_callback(
        '/s\:(\d+)\:\"(.*?)\";/s', 
        function ($matches){  return 's:'.strlen($matches[2]).':"'.$matches[2].'";';  },
        $serialized_string )
    ;
}
