?php
$conn=mysql_connect("localhost","root","");
$select=mysql_select_db("books",$conn);
$query="insert into computers(name,price,publish_data) ";
$query.="values('JSP',28.00,'2008-11-1')";
$query="select * from computers";
$result=mysql_query($query);
//以下是使用mysql_result()函数来获取到查询结果
$num=mysql_num_rows($result);
for($rows_count=0;$rows_count$num;$rows_count++){
echo "书名：".mysql_result($result,$rows_count,"name");
echo "价格：".mysql_result($result,$rows_count,"price");
echo "出版日期：".mysql_result($result,$rows_count,"publish_data")."br";
}
//以下是使用mysql_fetch_row()函数来获取到查询结果
while($row=mysql_fetch_row($result))
{
echo "书号：".$row[0]."br";
echo "书名：".$row[1]."br";
echo "价格：".$row[2]."br";
echo "出版日期：".$row[3]."br";
echo "br";
}
//以下是使用mysql_fetch_array()函数来获取到查询结果
while($row=mysql_fetch_array($result))
{
echo "书号：".$row[0]."br";
echo "书名：".$row[1]."br";
echo "价格：".$row["price"]."br";
echo "出版日期：".$row["publish_data"]."br";
echo "br";
}
//以下是使用mysql_fetch_object()函数来获取到查询结果
while($row=mysql_fetch_object($result))

echo "书名：".$row-name."br";

试编写代码如下：
?php
//从数据库根据 id 获取颜色
function getColor($db, $id)
{
if ($result = $db-query("SELECT * FROM color where id='" . $id . "'"))
{
$row = $result-fetch_assoc();
return $row['color'];
}
return '#000000';
}
$mysqli = new mysqli("localhost", "test", "test", "room");
if ($mysqli-connect_error) {
printf("数据库连接错误: %s\n", mysqli_connect_error());
exit();
}
?
table border="1" cellspacing="0"
tr
td bgcolor="?php echo getColor($mysqli,'1')?"1/td
/tr
tr
td bgcolor="?php echo getColor($mysqli,'2')?"2/td
/tr
tr
td bgcolor="?php echo getColor($mysqli,'3')?"3/td
/tr
/table
?php
$mysqli-close();
?
代码如下：?View
Code
PHP
include("conn.php");//调用数据库连接文件
echo
"table

$SQL
=
"select

$query
=
mysql_query($SQL);
//SQL查询语句
while
($row
=

//使用while循环mysql_fetch_array()并将数据返回数组
echo
