Mysql多重查詢和mysql_insert_id（）？

Question

嗨我重複與多個查詢的行，並希望從結果中獲取mysql_insert_id（）。複製工作正常，但我似乎無法從它得到最後一個ID。

這裏是我的代碼：

$mysqli = new mysqli("localhost", "xxxx", "xxxx", "xxxx"); 

if ($mysqli->connect_errno) { 
    echo($error_page_header); 
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error; 
    echo($error_page_footer); 
    exit; 
} 

$sql = "CREATE TEMPORARY TABLE tmp ENGINE=MEMORY SELECT * FROM test_table WHERE id=1; "; 
$sql.= "UPDATE tmp SET id=NULL; "; 
$sql.= "INSERT INTO test_table SELECT * FROM tmp; "; 
$sql.= "DROP TABLE tmp; "; 

if (!$mysqli->multi_query($sql)) { 
    echo($error_page_header); 
    echo "Multi query failed: (" . $mysqli->errno . ") " . $mysqli->error; 
    echo($error_page_footer); 
    exit; 

} do { 
    if ($res = $mysqli->store_result()) { 
     var_dump($res->fetch_all(MYSQLI_ASSOC)); 
     $res->free(); 
    } 

} while ($mysqli->more_results() && $mysqli->next_result());  

echo('id: ' . mysql_insert_id()); // prints 0

不要混淆.. ext/mysql和mysqli不兼容，不能相互使用。使用$mysqli->insert_id（它是每個連接）
