php如何取數(shù)據(jù)庫中內(nèi)容

試編寫代碼如下：

?php

//從數(shù)據(jù)庫根據(jù)?id?獲取顏色

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("數(shù)據(jù)庫連接錯誤:?%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();

php如何獲取數(shù)據(jù)庫信息

代碼如下：?View

Code

PHP

include("conn.php");//調(diào)用數(shù)據(jù)庫連接文件

echo

"table

width=572

height=56

border=0

cellspacing=1

";

//創(chuàng)建html表格

echo

"tr

echo

"th

width=33

scope=colid/th";

echo

"th

width=100

scope=coluser_name/th

scope=coluser_pass/th

";

echo

"th

width=100

scope=colstaus/th";

echo

"th

echo

$SQL

=

"select

from

user_info";

$query

=

mysql_query($SQL);

//SQL查詢語句

while

($row

=

mysql_fetch_array($query)){

//使用while循環(huán)mysql_fetch_array()并將數(shù)據(jù)返回數(shù)組

echo

"tr

onmouseout=this.style.backgroundColor=''

onMouseOver=this.style.backgroundColor='#99CC33'

bgcolor=#CCCCCC";

echo

"td$row[0]/td";

//輸出數(shù)組中數(shù)據(jù)

echo

"td$row[1]/td";

echo

"td$row[2]/td";

echo

"td$row[3]/td";

echo

"td$row[4]/td";

echo

"/tr";

}

echo

"/table";輸出記錄截圖
