AMFPHP乱码问题

php档用dreamweaver UTF-8 no Bom 存档 , 用notepad存做utf-8 会令amfphp报错"invalid amf message".
php.ini
default_charset = "utf-8"
my.ini
default-character-set = utf8
character_set_server =  utf8
gateway.php
$gateway->setCharsetHandler( "iconv", "UTF-8", "gbk" );
将input 转为utf8
$ID = iconv("gbk","utf-8",$ID);
$ID = iconv("BIG5","utf-8",$ID);
INSERT VALUES 时,记得
SET NAMES "UTF8";
查看mysql 现时charset
mysql> show variables like "character%";
+--------------------------+---------------------------------------------------------+

还有collation编码
mysql> SHOW VARIABLES LIKE 'collation_%';
+----------------------+-----------------+
| Variable_name        | Value           |
+----------------------+-----------------+
| collation_connection | utf8_general_ci |
| collation_database   | big5_chinese_ci |
| collation_server     | utf8_general_ci |
