一、PHP語法
string mysql_client_encoding ([ resource $link_identifier = NULL ] )
適用php4.3.0以上,php5



二、MySQL5查詢語法：
SHOW VARIABLES LIKE 'character_set%';

報行結果Variable_name和Value兩個欄位
Variable_name            Value
----------------------------------
character_set_client        xxx
character_set_connection    xxx
character_set_database      xxx
