<a href="https://www.baidu.com/s?wd=mysql_select_db&tn=44039180_cpr&fenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1Y3PjR1P1csPhDYujnLPHIW0AP8IA3qPjfsn1bkrjKxmLKz0ZNzUjdCIZwsrBtEXh9GuA7EQhF9pywdQhPEUiqkIyN1IA-EUBtdPHnvP1czrjb" target="_blank" class="baidu-highlight">mysql_select_db</a>('db_name',$conn);//db_name是你的数据库名字
$sql='delete from table_name where id=1';//table_name是你的表名 where后跟的是删除的条件
mysql_query($sql,$conn);
mysql_close($conn);//关闭连接 养成好习惯！
