插入數據
MySQL插入數據
MySQL 表中使用 INSERT INTO SQL語句來插入數據。
你可以通過 mysql> 命令提示窗口中向數據表中插入數據，或者通過PHP腳本來插入數據。
以下爲向MySQL數據表插入數據通用的 INSERT INTO SQL語法：
INSERT INTO table_name ( field1, field2,...fieldN )
VALUES
( value1, value2,...valueN );通過命令提示窗口插入數據
以下我們將使用 SQL INSERT INTO 語句向 MySQL 數據表 runoob_tbl 插入數據
實例：
root@host# mysql -u root -p password;
Enter password:*******
mysql> use RUNOOB;
Database changed
mysql> INSERT INTO runoob_tbl
->(runoob_title, runoob_author, submission_date)
->VALUES
->("Learn PHP", "John Poul", NOW());
Query OK, 1 row affected (0.01 sec)
mysql> INSERT INTO runoob_tbl
->(runoob_title, runoob_author, submission_date)
->VALUES
->("Learn MySQL", "Abdul S", NOW());
Query OK, 1 row affected (0.01 sec)
mysql> INSERT INTO runoob_tbl
->(runoob_title, runoob_author, submission_date)
->VALUES
->("JAVA Tutorial", "Sanjay", '2007-05-06');
Query OK, 1 row affected (0.01 sec)

</html>在我們接收用戶提交的數據時，爲了數據的安全性我們需要使用 get_magic_quotes_gpc() 函數來判斷特殊字符的轉義是否已經開啓。如果這個選項爲off（未開啓），返回0，那麼我們就必須調用addslashes 這個函數來爲字符串增加轉義。
