PHP MySql增删改查，phpmysql增删改
mysql_connect()连接数据库
mysql_select_db选择数据库
mysql_fetch_assoc()获取结果集
mysql_query()执行sql语句
实例如下：
$con=@mysql_connect('localhost','root','root');//连接数据库
mysql_select_db('test',$con);//选择数据库
$userInfo=mysql_query("select * from user",$con);//创建sql语句
echo "
| "; echo $row['id'];//获取行中的id echo " | ";"; echo $row['username']; echo " | ";"; echo $row['password']; echo " | ";
mysql_free_result($userInfo);//释放结果集
mysql_close($con); //关闭数据库
/*delete
$d=@mysql_connect('localhost','root','root');
mysql_select_db('test',$d);
mysql_query("delete from user where id=1",$d);
mysql_close($d);
*/
/*insert
$i=@mysql_connect('localhost','root','root');
mysql_select_db('test',$i);
mysql_query("insert into user(username,password) values('ad','ad')",$i);
mysql_close($i);
*/
//update
$u=@mysql_connect('localhost','root','root');
mysql_select_db('test',$u);
mysql_query("update user set username='aaa' where username='00'",$u);
