将php连接到sql server

我正在使用wamp服务器。我使用dreamweaver创建php文件。 这是我的密码：

     -untitled.php
    <?php
 include 'E:\wamp\www\PHP\connection.php';
 $query ="SELECT * FROM students";
 $result = mysql_query($query);
 while($students = mysql_fetch_array($result)) {
     echo "<h3>".$students['LNAME'] ."</H3>";
 }
   ?>
   <h1>Create A user</h1>
<form action="create.php" method="post">
<input type="text" name="LName" value="" />
<input type="text" name="FName" value="" />
<input type="text" name="MName" value="" />
<input type="text" name="GradeOrYear" value="" />
<input type="text" name="Address" value="" />
<br/>
 <input type="submit" name="Submit" value="" />
</form>

      -Connection.php

     <?php
  $dbhost = 'localhost';
  $dbuser- 'root';
  $dbpass= '';
  $dbname = 'koro';
  $conn =mysql_connect($dbhost, $dbuser, $dbpass);
  mysql_select_db($db);
 ?>

-untitled.php
创建用户

      -Connection.php

     <?php
  $dbhost = 'localhost';
  $dbuser- 'root';
  $dbpass= '';
  $dbname = 'koro';
  $conn =mysql_connect($dbhost, $dbuser, $dbpass);
  mysql_select_db($db);
 ?>

-Connection.php

但我得到了这个错误：

      -Connection.php

     <?php
  $dbhost = 'localhost';
  $dbuser- 'root';
  $dbpass= '';
  $dbname = 'koro';
  $conn =mysql_connect($dbhost, $dbuser, $dbpass);
  mysql_select_db($db);
 ?>

---

请问，我如何修复此错误？

您的意思是

$dbuser='root'$dbuser='root'可能会改为？
+1到Ignacio-您有$dbuser-'root'而不是$dbuser='root'+1到Ignacio-您有$dbuser-'root'而不是$dbuser='root'
      -Connection.php

     <?php
  $dbhost = 'localhost';
  $dbuser- 'root';
  $dbpass= '';
  $dbname = 'koro';
  $conn =mysql_connect($dbhost, $dbuser, $dbpass);
  mysql_select_db($db);
 ?>
