SQL server php登录脚本

我已经创建了脚本来验证我的登录系统，但是我很难弄清楚如何让它专门登录到我的

sqlserver

帐户到我的特定工作空间我的登录脚本如下所示

<?php
    session_start();

    if(!isset($_SESSION["user_id"])){
        header("location:../../login.html");
    }

    $username = $_POST['txt_username'];
    $user_id = $_POST['txt_password'];


    mysql_connect($server, $username, $password) or die("No Server Found");

    mysql_select_db($schema) or die("No Connection");

?>

下面是连接到MSSQL服务器数据库的代码

//connection to the database
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
  or die("Couldn't connect to SQL Server on $myServer"); 

//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
  or die("Couldn't open database $myDB"); 

//declare the SQL statement that will query the database
$query = "SELECT id, name, year ";
$query .= "FROM cars ";
$query .= "WHERE name='BMW'"; 

//execute the SQL query and return records
$result = mssql_query($query);

$numRows = mssql_num_rows($result); 
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>"; 

//display the results 
while($row = mssql_fetch_array($result))
{
  echo "<li>" . $row["id"] . $row["name"] . $row["year"] . "</li>";
}
//close the connection
mssql_close($dbhandle);
?>

//与数据库的连接
//connection to the database
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
  or die("Couldn't connect to SQL Server on $myServer"); 

//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
  or die("Couldn't open database $myDB"); 

//declare the SQL statement that will query the database
$query = "SELECT id, name, year ";
$query .= "FROM cars ";
$query .= "WHERE name='BMW'"; 

//execute the SQL query and return records
$result = mssql_query($query);

$numRows = mssql_num_rows($result);

//display the results 
while($row = mssql_fetch_array($result))
{
  echo "<li>" . $row["id"] . $row["name"] . $row["year"] . "</li>";
}
//close the connection
mssql_close($dbhandle);
?>

$dbhandle=mssql\u connect（$myServer、$myUser、$myPass）
或者死亡（“无法连接到$myServer上的SQL Server”）；
//选择要使用的数据库
//connection to the database
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
  or die("Couldn't connect to SQL Server on $myServer"); 

//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
  or die("Couldn't open database $myDB"); 

//declare the SQL statement that will query the database
$query = "SELECT id, name, year ";
$query .= "FROM cars ";
$query .= "WHERE name='BMW'"; 

//execute the SQL query and return records
$result = mssql_query($query);

$numRows = mssql_num_rows($result); 
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>"; 

//display the results 
while($row = mssql_fetch_array($result))
{
  echo "<li>" . $row["id"] . $row["name"] . $row["year"] . "</li>";
}
//close the connection
mssql_close($dbhandle);
?>

$selected=mssql\u select\u db（$myDB，$dbhandle）
或者死亡（“无法打开数据库$myDB”）；
//connection to the database

  or die("Couldn't connect to SQL Server on $myServer"); 

//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
  or die("Couldn't open database $myDB"); 

//declare the SQL statement that will query the database
$query = "SELECT id, name, year ";
$query .= "FROM cars ";
$query .= "WHERE name='BMW'"; 

//execute the SQL query and return records
$result = mssql_query($query);

$numRows = mssql_num_rows($result); 
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>"; 

//display the results 
while($row = mssql_fetch_array($result))
{
  echo "<li>" . $row["id"] . $row["name"] . $row["year"] . "</li>";
}
//close the connection
mssql_close($dbhandle);
?>

//声明将查询数据库的SQL语句
//connection to the database
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
  or die("Couldn't connect to SQL Server on $myServer"); 

//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
  or die("Couldn't open database $myDB"); 

//declare the SQL statement that will query the database
$query = "SELECT id, name, year ";

//execute the SQL query and return records
$result = mssql_query($query);

使用DSN连接

DSN代表“数据源名称”。这是一种为数据源分配有用且易于记忆的名称的简单方法，数据源可能不仅仅限于数据库

//connection to the database
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
  or die("Couldn't connect to SQL Server on $myServer"); 

//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
  or die("Couldn't open database $myDB"); 

//declare the SQL statement that will query the database
$query = "SELECT id, name, year ";
$query .= "FROM cars ";
$query .= "WHERE name='BMW'"; 

//execute the SQL query and return records
$result = mssql_query($query);

$numRows = mssql_num_rows($result); 
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>"; 

//display the results 
while($row = mssql_fetch_array($result))
{
  echo "<li>" . $row["id"] . $row["name"] . $row["year"] . "</li>";
}
//close the connection
mssql_close($dbhandle);
?>

在下面的示例中，我们将向您展示如何使用DSN连接到名为“examples”的MSSQL服务器数据库，并从表“cars”中检索所有记录

//connection to the database
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
  or die("Couldn't connect to SQL Server on $myServer"); 

//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
  or die("Couldn't open database $myDB"); 

//declare the SQL statement that will query the database
$query = "SELECT id, name, year ";
$query .= "FROM cars ";
$query .= "WHERE name='BMW'"; 

//execute the SQL query and return records
$result = mssql_query($query);

$numRows = mssql_num_rows($result); 
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>"; 

//display the results 
while($row = mssql_fetch_array($result))
{
  echo "<li>" . $row["id"] . $row["name"] . $row["year"] . "</li>";
}
//close the connection
mssql_close($dbhandle);
?>

<?php 

//connect to a DSN "myDSN" 
$conn = odbc_connect('myDSN','',''); 

if ($conn) 
{ 
  //the SQL statement that will query the database 
  $query = "select * from cars"; 
  //perform the query 
  $result=odbc_exec($conn, $query); 

  echo "<table border=\"1\"><tr>"; 

  //print field name 
  $colName = odbc_num_fields($result); 
  for ($j=1; $j<= $colName; $j++) 
  {  
    echo "<th>"; 
    echo odbc_field_name ($result, $j ); 
    echo "</th>"; 
  } 

  //fetch tha data from the database 
  while(odbc_fetch_row($result)) 
  { 
    echo "<tr>"; 
    for($i=1;$i<=odbc_num_fields($result);$i++) 
    { 
      echo "<td>"; 
      echo odbc_result($result,$i); 
      echo "</td>"; 
    } 
    echo "</tr>"; 
  } 

  echo "</td> </tr>"; 
  echo "</table >"; 

  //close the connection 
  odbc_close ($conn); 
} 
else echo "odbc not connected"; 
?>

这实际上并没有连接到数据库以允许我获取登录详细信息。这里是检查用户名和密码的查询？请告诉我您使用的是Microsoft SQL server还是Mysql数据库。如果您使用的是SQL server。按照下面的编码//创建指向MSSQL$link=MSSQL_connect（'KALLESPC\SQLEXPRESS'，'root'，'pass'）的链接；//选择数据库“php”mssql\u Select\u db（'database1'，$link）；SQL server也是我无法找到的，我已经做了研究，但它似乎回到了我无法理解的代码位感谢这是一个很大的帮助。

//connection to the database
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
  or die("Couldn't connect to SQL Server on $myServer"); 

//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
  or die("Couldn't open database $myDB"); 

//declare the SQL statement that will query the database
$query = "SELECT id, name, year ";
$query .= "FROM cars ";
$query .= "WHERE name='BMW'"; 

//execute the SQL query and return records
$result = mssql_query($query);

$numRows = mssql_num_rows($result); 
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>"; 

//display the results 
while($row = mssql_fetch_array($result))
{
  echo "<li>" . $row["id"] . $row["name"] . $row["year"] . "</li>";
}
//close the connection
mssql_close($dbhandle);
