php怎么鏈接sqlserver數據庫進行增刪改查

php有專門的sql server操作函數，舉個簡單的例子，是查詢的

$serverName?=?"localhost";?//數據庫服務器地址

$uid?=?"root";?//數據庫用戶名

$pwd?=?"123456";?//數據庫密碼

$connectionInfo?=?array("UID"=$uid,?"PWD"=$pwd,?"Database"='databasename');

$conn?=?sqlsrv_connect(?$serverName,?$connectionInfo);

if(?$conn?==?false){

echo?"連接數據庫失敗！";

die(?print_r(?sqlsrv_errors(),?true));

}

$sql?=?"select?*?from?user";

$query?=?sqlsrv_query(?$conn,?$sql?,?array(),?array(?"Scrollable"?=?SQLSRV_CURSOR_KEYSET?));

$num_rows?=?sqlsrv_num_rows($query);

if($num_rows??0){

while?($row?=?sqlsrv_fetch_array($query)){

echo?$row['aaaa'];

}

}

其它的操作也同理，舉一反三

php封裝一個class類，實現mysql數據庫的增刪改查怎么操做？

class sqlHelper{ \x0d\x0a public $conn; \x0d\x0a public $dbname="數據庫名稱"; \x0d\x0a public $username="數據庫用戶名"; \x0d\x0a public $password="數據庫密碼"; \x0d\x0a public $host="localhost"; \x0d\x0a //連接數據庫 \x0d\x0a public function __construct(){ \x0d\x0a $this-conn=mysql_connect($this-host,$this-username,$this-password); \x0d\x0a if(!$this-conn){ \x0d\x0a die("連接失敗".mysql_error()); \x0d\x0a } \x0d\x0a mysql_select_db($this-dbname,$this-conn); \x0d\x0a } \x0d\x0a //執行查詢語句 \x0d\x0a public function execute_dql($sql){ \x0d\x0a $res=mysql_query($sql,$this-conn); \x0d\x0a return $res; \x0d\x0a } \x0d\x0a //執行增填改語句 \x0d\x0a public function execute_dml($sql){ \x0d\x0a $b=mysql_query($sql,$this-conn); \x0d\x0a if(!$b){ \x0d\x0a return 3; \x0d\x0a }else{ \x0d\x0a if(mysql_affected_rows($this-conn)){ \x0d\x0a return 1;//表示OK \x0d\x0a }else{ \x0d\x0a return 2;//表示沒有行收到影響 \x0d\x0a } \x0d\x0a } \x0d\x0a }\x0d\x0a}

如何用PHP代碼實現MySQL數據庫的增刪改查

?php

$con = mysql_connect("localhost:3306","root","");

if (!$con) {

die('Could not connect: ' . mysql_error());

}

mysql_select_db("test", $con);

$result = mysql_query("SELECT * FROM user");

echo "table border='1'

tr

thUsername/th

thPassword/th

/tr";

while($row = mysql_fetch_array($result)) {

echo "tr";

echo "td" . $row['username'] . "/td";

echo "td" . $row['password'] . "/td";

echo "/tr";

}

echo "/table";

mysql_close($con);

?

從服務器中獲取用戶所有信息（SQL SELECT語句）并以表格形式出現

?php

$con = mysql_connect("localhost","root","");

if (!$con) {

die('Could not connect: ' . mysql_error());

}

mysql_select_db("test", $con);

mysql_query("DELETE FROM user WHERE username = '$_POST[username]'");

mysql_close($con);

?

刪除該用戶所有信息delete.php

?php

$con = mysql_connect("localhost:3306","root","");

if (!$con) {

die('Could not connect: ' . mysql_error());

}

mysql_select_db("test", $con);

$sql = "INSERT INTO user (username,password)

VALUES

('$_POST[username]','$_POST[password]')";

if (!mysql_query($sql,$con)) {

die('Error: ' . mysql_error());

}

echo "1 record added";

mysql_close($con);

?

注冊一個新用戶insert.php

?php

$con = mysql_connect("localhost","root","");

if (!$con) {

die('Could not connect: ' . mysql_error());

}

mysql_select_db("test", $con);

mysql_query("UPDATE user SET password = '$_POST[password]' WHERE username = '$_POST[username]'");

mysql_close($con);

?

修改一個用戶密碼update.php

titleFORM/title

/head

body

br /

h1Insert:/h1

form action="insert.php" method="post"

username:input type="name" name="username"/

br /

password:input type="password" name="password"/

input type="submit" value="submit"/

/form

br /hr /br /

h1Delete/h1

form action="delete.php" method="post"

username:input type="name" name="username" /

br /

Are you sure?input type="submit" value="sure" /

/form

h1Update/h1

form action="update.php" method="post"

username:input type="name" name="username"/

br /

You want to change your password into:input type="password" name="password"/

input type="submit" value="submit"/

/form
