php查詢數(shù)據(jù)與數(shù)據(jù)庫內(nèi)信息不一致,該怎么解決?

1.有可能有緩存,你可以更新下緩存。

2.檢查下數(shù)據(jù)庫配置方面的信息,看看是否配置正確。

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

//創(chuàng)建html表格

如何正確理解PHP獲取顯示數(shù)據(jù)庫數(shù)據(jù)函數(shù)

1、PHP獲取顯示數(shù)據(jù)庫數(shù)據(jù)函數(shù)之 mysql_result()

mixed mysql_result(resource result_set, int row [,mixed field])

從result_set 的指定row 中獲取一個field 的數(shù)據(jù). 簡單但是效率低.

舉例:

$link1 = @mysql_connect("server1",

"webuser", "password")

or die("Could not connect

to mysql server!");

@mysql_select_db("company")

or die("Could not select database!");

$query = "select id, name

from product order by name";

$result = mysql_query($query);

$id = mysql_result($result, 0, "id");

$name = mysql_result($result, 0, "name");

mysql_close();

注意,上述代碼只是輸出結(jié)果集中的第一條數(shù)據(jù)的字段值,如果要輸出所有記錄,需要循環(huán)處理.

for ($i = 0; $i = mysql_num_rows($result); $i++)

{

$id = mysql_result($result, 0, "id");

$name = mysql_result($result, 0, "name");

echo "Product: $name ($id)";

}

注意,如果查詢字段名是別名,則mysql_result中就使用別名.

2、PHP獲取顯示數(shù)據(jù)庫數(shù)據(jù)函數(shù)之mysql_fetch_row()

array mysql_fetch_row(resource result_set)

從result_set中獲取整行,把數(shù)據(jù)放入數(shù)組中.

舉例(注意和list 的巧妙配合):

$query = "select id,

name from product order by name";

$result = mysql_query($query);

while(list($id, $name)

= mysql_fetch_row($result)) {

echo "Product: $name ($id)";

}

3、PHP獲取顯示數(shù)據(jù)庫數(shù)據(jù)函數(shù)之mysql_fetch_array()

array mysql_fetch_array(resource result_set [,int result_type])

mysql_fetch_row()的增強版.

將result_set的每一行獲取為一個關(guān)聯(lián)數(shù)組或/和數(shù)值索引數(shù)組.

默認獲取兩種數(shù)組,result_type可以設(shè)置:

MYSQL_ASSOC:返回關(guān)聯(lián)數(shù)組,字段名=字段值

MYSQL_NUM:返回數(shù)值索引數(shù)組.

MYSQL_BOTH:獲取兩種數(shù)組.因此每個字段可以按索引偏移引用,也可以按字段名引用.

舉例:

$query = "select id,

name from product order by name";

$result = mysql_query($query);

while($row = mysql_fetch_array

($result, MYSQL_BOTH)) {

$name = $row['name'];

//或者 $name = $row[1];

$name = $row['id'];

//或者 $name = $row[0];

echo "Product: $name ($id)";

}

4、PHP獲取顯示數(shù)據(jù)庫數(shù)據(jù)函數(shù)之mysql_fetch_assoc()

array mysql_fetch_assoc(resource result_set)

相當于 mysql_fetch_array($result, MYSQL_ASSOC)

5、PHP獲取顯示數(shù)據(jù)庫數(shù)據(jù)函數(shù)之mysql_fetch_object()

object mysql_fetch_object(resource result_set)

和mysql_fetch_array()功能一樣,不過返回的不是數(shù)組,而是一個對象.

舉例:

$query = "select id, name

from product order by name";

$result = mysql_query($query);

while($row = mysql_fetch_object

($result)) {

$name = $row-name;

$name = $row-id;

echo "Product: $name ($id)";

}

以上這些函數(shù)就是PHP獲取顯示數(shù)據(jù)庫數(shù)據(jù)函數(shù)的全部總結(jié)。

php怎么從其他的數(shù)據(jù)庫里面取數(shù)據(jù)

$con=mysql_connect('localhost','root','');//數(shù)據(jù)庫信息

mysql_select_db('shop');//數(shù)據(jù)庫名

mysql_query("set?names?utf8");//設(shè)置字符集編碼

$sql="select?goods_name,goods_number,shop_price?from?goods";//查詢語句

$res=mysql_query($sql);//執(zhí)行查詢

while($row=mysql_fetch_assoc($res)){

$rows[]=$row;//接受結(jié)果集

}

//遍歷數(shù)組

foreach($rows?as?$key=$v){

echo?$v['goods_name']."---".$v['goods_number']."---".$v['shop_price']."";

}

布局可以自己寫的。數(shù)據(jù)從foreach循環(huán)里取出。
