Attribute Mapping with key path

Hello

It would be nice to manage path in “Attribute Mapping” keys, like “key.subkey”. It’ll permit to access value in user info api result.

If you have a git somewhere I can send you a pull request.

I did a try with code like

/**
     * Retrieve a key in a structured data.
     * Key path separator is "." like "k1.k2".
     */
    public static function array_getKeyPath( Array & $array, $keyPath, $default = null )
    {
        if( empty($array) || (! is_array($array)) )
            return $default ;
        $ar =& $array ;
        $value = $default ;
        foreach( explode('.',$keyPath) as $key )
        {
            if( isset($ar[$key]) )
            {
                $value = $ar[$key];
                $ar =& $ar[$key] ;
            }
            else
            {
                return $default ;
            }
        }
        return $value ;
    }
