php 购物车完整实现代码

.代码如下:

<table width="255" cellspacing="0" cellpadding="0">

<tr>

<td width="130" rowspan="6"><div align="center">

<?php

if(trim($info[tupian]==""))

{

echo "暂无图片";

}

else

{

?>

<img src="<?php echo $info[tupian];?>" width="130" height="100" >

<?php

}

?>

</div></td>

<td width="20" height="16"> </td>

<td width="113"><font color="EF9C3E">【<?php echo $info[mingcheng];?>】</font></td>

}

else

{

echo "已售完";

}

?>】</font></td>

</tr>

</table>

<?php

}

4、数据库配置文件conn.php

.代码如下:

<?php

$conn=mysql_connect("localhost","root","") or die("数据库服务器连接错误".mysql_error());

mysql_select_db("shop",$conn) or die("数据库访问错误".mysql_error());

mysql_query("set character set gb2312");

mysql_query("set names gb2312");

?>
