php连接mysql与mssql 2005数据库代码

php教程连接mssql 2005 1.下载以下两个文件,放入php ext目录及system32

php_sqlsrv_52_ts_vc6.dll   (线程安全)

php_sqlsrv_52_nts_vc6.dll (非线程安全)

vc6用于apache,vc9用于iis

2.修改php.ini

extension=php_sqlsrv_52_ts_vc6.dll

3.下载sqlncli.msi，微软官方可以下

安装的时候提示是sql server 2008的，不过2005也是可以用的。

4.测试代码

<?php

$servername = "127.0.0.1";
$connectioninfo = array("database"=>"testdb","uid"=>"test","pwd"=>"test");
$conn = sqlsrv_connect($servername, $connectioninfo);

if($conn) {
    echo "connection established.<br>";
} else {
    echo "connection could not be established.<br>";
    die(print_r(sqlsrv_errors(), true));
    exit();
}

$sql = "select * from t_employee";
$result = sqlsrv_query($conn,$sql);
$data = array();
while($row=sqlsrv_fetch_array($result)) {
    $data[] = $row;
}

foreach($data as $p) {
    echo $p['name']."<br>";
}

sqlsrv_close($conn);

echo "<br> done <br>";
echo date("y-m-d h:i:s");

?>

下面总结了三种流行的数据库教程如何利用php教程 来调用它们的存储过程，我们讲有mysql教程,oracle,mssql server哦。

<?php
function check_login($user, $pass) {
         $conn = ocilogon('user', 'pass', 'database');
         $sql = 'begin :result := test.check_login(:user, :pass); end;';
         $stmt = oci_parse($conn, $sql);
        
         $result = '';
         oci_bind_by_name($stmt, ':user', $user, 32);
         oci_bind_by_name($stmt, ':pass', md5($pass), 32);
         oci_bind_by_name($stmt, ':result', $result, 10);
         oci_execute($stmt);
         ocilogoff($conn);
        
         return $result;
}
?>

调用mysql

存储过程改成：
create procedure in_out(in uid int) begin
set @msg='hello';
select *,@msg from manage_loginhistory where h_uid=uid;
end;
php调用改成：
$sql = "call in_out(39)";
$rs=mysql_query($sql);
$row=mysql_fetch_array($rs);

调用ms sql server

$user_name = '龙之泪';      //声明一个变量，用做存储过程的输入参数
   $password = '123456';       //再声明一个变量，用做存储过程的另一个输入参数
   $info = '';                            //$info，用来接受从存储过程输出的参数值
   $host="192.168.0.1";         //定义数据库服务器
   $user="sa";                        //连接用户名
   $password="123456";        //连接密码
   $db="sample";                    //数据库名称
   $dblink=mssql_connect($host,$user,$password) or die("can't connect to mssql"); //连接数据库服务器
   mssql_select_db($db,$dblink)   or die("can't select sample");//选择数据库

   $sp = mssql_init("test");  //初始化一个存储过程

   //为存储过程添加一个参数，@user_name为参数名，$user_name为参数对应的php变量，sqlvarchar表明该参数类型为sql server的varchar类型，第一个false表示该参数不是输出参数，即该参数是输入参数，第二个false表示该参数不允许为null，最后的30表示该变量的长度为30
   mssql_bind($sp,"@user_name",$user_name,sqlvarchar,false,false,30);
   mssql_bind($sp,"@password",$password,sqlvarchar,false,false,30);
   mssql_bind($sp,"@info",$info,sqlvarchar,true,false,30); //为存储过程添加一个输出参数
   mssql_execute($sp); //执行该存储过程

   echo $info; //打印出从存储过程中返回的输出参数值

在 windows 下安装 php教程 时，　为了避免配置文件混乱，将安装目录下的 php.ini 复制到 windows 目录下之后，应该将原来安装目录下的 php.ini 文件重命名或删除，以免造成在不同环境下执行时，查找配置文件不一致的情况发生

fatal error: undefined function mysql_connect()
　　环境: windows 2003, php 5.2.0, mysql 5.0, apache 2.0
　　在 php.ini 中, 已经将 php_mysql.dll 的模块选项给打开了；测试的脚本也很简单，就一个 mysql_conect 函数，内容如下:
复制代码 代码如下:

php.ini:
extension=php_mysql.dll
测试脚本 test.php 内容如下：
text.php
<?
if ( !mysql_connect(dbhost, dbuser,dbpwd) )
{
echo "连接失败!";
exit;
}
echo "连接成功!t";
?>
用 web 方式调用 http://localhost/test.php, 执行正常, 显示"连接成功".
　　但用 dos command 命令行的方式调用 d:/php/php.exe test.php 却显示连接失败, 错误信息为: fatal error: undefined function mysql_connect()
　　很显然, 在 dos command 命令行的环境下，mysql 的模块没有被调用。方法弄尽, 仍无法解决. 百思不得其解. 后来, 用写了个脚本, 看看 php 的配置, 在两个环境下有什么不同:
test.php
复制代码 代码如下:

<?
echo phpinfo();
?>

仔细查看两个环境下 phpinfo() 输入的 php 配置信息，终于发现了问题所在:
web 方式 http://localhost/test.php 方式调用时, 其 configuration file (php.ini) path 显示为 c:windowsphp.ini。
dos command 命令行方式 d:/php/php.exe test.php 调用时, 其 configuration file (php.ini) path 为 d:phpphp.ini。
　　而在 c:windows 和 d:php 目录下，　都存在一个 php.ini 文件，d:php 目录下的 php.ini 没有将 extension=php_mysql.dll 模块打开．于是将 d:phpphp.ini 删除，只保留 c:windowsphp.ini，问题解决．

操作时点击删除连接时就会会获取到当前条目的id然后程序获取到当前id进行删除操作。

<?php教程
       include("conn.php");
      
       $query = "select * from new order by id desc";
       $res = mysql教程_query($query);
       while($rows =mysql_fetch_array($res)){       //将查询到结果拆到$rows数组中
?>
<table>
       <tr>
              <td>标题:<?php echo$rows['title']?></td><td><a href="del.php?<?php $tid = $rows['id'] ?>">[删除]</a></td><td><a href="">[修改]</a></td>
