php编程 连接数据库 读取数据表的问题
我的数据库有多张数据表,只有表order不能读取 只能打印出111
其他任何一张表都能 就是会打印出222
不知道出了什么问题QAQ
<?php $corn=mysql_connect('localhost','root',''); mysql_query('set names UTF8',$corn); if(!$corn) die('Could not connect: ' . mysql_error()); $db_selected=mysql_select_db("daydream",$corn); if (!$db_selected) die ('Can\'t use foo : ' . mysql_error()); $query=mysql_query("select * from order "); if(!$query) echo 111; else echo 222;//这三行是用来测试是否读取到数据表 $row = mysql_fetch_array($query); echo" <div> <p class='item'>购物车编号:$row[cartNo]  客户编号:$row[cusNo]  商品编号:$row[proNo]  购买时间:$row[cartDate]  购买金额:$row[cartSum]  收货地址:$row[cartAddress] </input></p> </br> </div><p> "; echo"  </p>"; ?>
回复讨论(解决方案)
真的做到最后显示订单记录这里最容易的部分啊!!!!居然读不到订单表!!!!拜托大家帮我看看!!!实在想不出什么问题QAQ
下面是我的数据表和数据库
$query=mysql_query("select * from order ");
order 是??字
改成
$query=mysql_query("select * from `order `");
就可以了。
其?表名一般都不要用??字比?好,可以用orders?做。
$query=mysql_query("select * from `order` ");
表名不能使用关键字这个我知道
但是一但有关键字,就要用‘’起来。
只有表order不能读取 只能打印出111
其他任何一张表都能 就是会打印出222 其实从你的描述就已经知道问题所在了,就是order表的问题,什么问题呢,和关键字order一样,所以改一下表名吧,或者`order`
$query=mysql_query("select * from order ") or die(mysql_error());
提示什么不就知道了
mysql 保留字 http://www.cnblogs.com/lawdong/archive/2010/08/08/2357903.html
凡是将保留字挪作他用时都不需转义:用 `` 括起来
但如下保留字可以例外:
ACTION
BIT
DATE
ENUM
NO
TEXT
TIME
TIMESTAMP
原来是关键字的问题 谢谢大家啦 我知道啦 已经改好啦~~~~

PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.
