如何用php連接sql server數(shù)據(jù)庫？

我用的PHP版本是php5.6.12,mssql數(shù)據(jù)庫版本為2008

創(chuàng)新互聯(lián)建站憑借在網(wǎng)站建設(shè)、網(wǎng)站推廣領(lǐng)域領(lǐng)先的技術(shù)能力和多年的行業(yè)經(jīng)驗，為客戶提供超值的營銷型網(wǎng)站建設(shè)服務(wù)，我們始終認為：好的營銷型網(wǎng)站就是好的業(yè)務(wù)員。我們已成功為企業(yè)單位、個人等客戶提供了成都網(wǎng)站建設(shè)、成都做網(wǎng)站服務(wù)，以良好的商業(yè)信譽，完善的服務(wù)及深厚的技術(shù)力量處于同行領(lǐng)先地位。

兩種途徑：

1、直接連接

$servname="CAPTAINHERO567";

$conninfo=array(

"Database"="netdata",

"UID"="lxz2005",

"PWD"="831140");

$conn=sqlsrv_connect($servname,

$conninfo);

$sql="select

*

from

Pinfo";

$db=sqlsrv_query($conn,

$sql);

while($row=sqlsrv_fetch_array($db))

{

echo("

".iconv("GB2312","UTF-8",$row["Pname"])."

");

}

2、使用PDO抽象數(shù)據(jù)層連接

$hostname

=

"192.168.1.100";

$dbname

=

"Northwind";

$username

=

"sa";

$pwd

=

"pwd100";

$dsn="sqlsrv:Server=$hostname;database=$dbname";

$conn

=

new

PDO

($dsn,$username,$pwd);

$conn-setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);

echo

"mssql

database

connnection

sucessed!";

php怎么連接mysql數(shù)據(jù)庫并導(dǎo)入數(shù)據(jù)？

方法/步驟

1

登錄到phpMyAdmin

2

新建一個要導(dǎo)入的數(shù)據(jù)庫，點擊“+new”

3

如圖，分別填寫數(shù)據(jù)庫名稱，以及選擇數(shù)據(jù)庫的排序規(guī)則，

4

完成步驟3，點擊“創(chuàng)建”

5

完成步驟4，從右側(cè)就可以看到我們新創(chuàng)建的數(shù)據(jù)庫了，如果沒有立即顯示，刷新即可立馬顯示了。

6

單擊我們新創(chuàng)建的數(shù)據(jù)庫，

7

然后，我們選擇“導(dǎo)入”，

8

完成步驟7，我們點擊“選擇文件”，

9

點擊了“選擇文件”之后，就會出現(xiàn)如圖所示的彈出框，我們選擇要導(dǎo)入的sql就可以了，后綴名可以是.sql，也可以是壓縮文件.zip。如圖，選擇好文件之后，點擊“確定”就可以了

10

完成步驟⑨，你就可以從剛才的頁面中看到自己上傳的文件了，如圖所示，其余選項默認就可以了，然后點擊“執(zhí)行”就可以了。

11

這個時候，你就可以看到你的數(shù)據(jù)已經(jīng)導(dǎo)入到你新創(chuàng)建的數(shù)據(jù)庫中了

怎樣用PHP連接sql數(shù)據(jù)庫

1、學(xué)習(xí)的方法，最好是看手冊

在前一篇文章中涉及到了連接數(shù)據(jù)庫sqlsrv_connect();還記得我們mysql連接數(shù)據(jù)庫的時候也是mysql_connect();兩者操作數(shù)據(jù)庫是很相似的。從零基礎(chǔ)開始學(xué)起的話，只能是查閱手冊。查看一下sqlsrv有哪些函數(shù)提供我們使用！推薦網(wǎng)址是：

【注意】很多的方法都跟mysql提供的方法很相似，看到后面的函數(shù)名就大概知道里面的用法，比如說mysql執(zhí)行sql語句的時候調(diào)用mysql_query();而sqlserver執(zhí)行sql語句的時候調(diào)用也是sqlsrv_query()，但是特別注意一點就是，它們的傳遞參數(shù)不一樣。詳細的只能看一下手冊。接下來我簡單總結(jié)一下操作數(shù)據(jù)的方法

2、連接數(shù)據(jù)庫sqlsrv_connect()

?php$serverName = "serverName\sqlexpress";//服務(wù)器的名字，本地localhost$connectionInfo = array( "Database"="dbName", "UID"="userName", "PWD"="password");$conn = sqlsrv_connect( $serverName, $connectionInfo);if( $conn ) { ? ? echo "Connection established.br /";

}else{ ? ? echo "Connection could not be established.br /"; ? ? die( print_r( sqlsrv_errors(), true));

}

3、操作數(shù)據(jù)庫

1）執(zhí)行sql語句sqlsrv_query()，返回值為true或者false，這里函數(shù)的用法跟mysql_query()，不一樣。它需要把連接的資源句柄當(dāng)作參數(shù)傳進去，看源碼。資源句柄就是上面代碼連接數(shù)據(jù)庫的“$conn”。

$sql = "select * from test1"; ? //sql語句$data = sqlsrv_query($conn,$sql); ?//$conn資源句柄if($data == true){ ? ?die("執(zhí)行成功");

}else{ ? ?die("執(zhí)行失敗");

}

2）獲取結(jié)果集

//以數(shù)值索引數(shù)組、關(guān)聯(lián)數(shù)組或這兩種數(shù)組的形式檢索下一行的數(shù)據(jù)。類似于mysql_fetch_arraysqlsrv_fetch_array ?

//以對象形式檢索下一行的數(shù)據(jù)。sqlsrv_fetch_object 1234

$sql = "select * from test1";$data = sqlsrv_query($conn,$sql);if($data == true){ ? ?while($row = sqlsrv_fetch_array( $data, SQLSRV_FETCH_ASSOC) ) { ? ? ? ? ?echo $row['id'].", ".$row['name']."br /";

}else{ ? ? ? ? die( print_r( sqlsrv_errors(), true));

}

}

$sql = "SELECT fName, lName FROM Table_1";$stmt = sqlsrv_query( $conn, $sql);if( $stmt === false ) { ? ? die( print_r( sqlsrv_errors(), true));

}while( $obj = sqlsrv_fetch_object( $stmt)) { ? ? ?echo $obj-fName.", ".$obj-lName."br /";

}

3）顯示錯誤信息sqlsrv_errors()：上面都有用到這個函數(shù)，只要是操作數(shù)據(jù)庫發(fā)生錯誤，都可以使用這個函數(shù)打印出來看一下壓

這里就不用上代碼了
