MS SQL Server 2000 and PHP

I have a database created inside Helm running MS SQL Server 2000. I want to connect to the database using PHP. I tried all the following codes:

Code 1:

<?php
$myServer = "localhost";
$myUser = "your_name";
$myPass = "your_password";
$myDB = "examples";

//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);
?>

Code 2:

<?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";
?>

Code 3:

<?php
$myServer = "localhost";
$myUser = "your_name";
$myPass = "your_password";
$myDB = "examples";

//create an instance of the  ADO connection object
$conn = new COM ("ADODB.Connection")
  or die("Cannot start ADO");

//define connection string, specify database driver
$connStr = "PROVIDER=SQLOLEDB;SERVER=".$myServer.";UID=".$myUser.";PWD=".$myPass.";DATABASE=".$myDB;
  $conn->open($connStr); //Open the connection to the database

//declare the SQL statement that will query the database
$query = "SELECT * FROM cars";

//execute the SQL statement and return records
$rs = $conn->execute($query);

$num_columns = $rs->Fields->Count();
echo $num_columns . "<br>"; 

for ($i=0; $i < $num_columns; $i++) {
    $fld[$i] = $rs->Fields($i);
}

echo "<table>";

while (!$rs->EOF)  //carry on looping through while there are records
{
    echo "<tr>";
    for ($i=0; $i < $num_columns; $i++) {
        echo "<td>" . $fld[$i]->value . "</td>";
    }
    echo "</tr>";
    $rs->MoveNext(); //move on to the next record
}


echo "</table>";

//close the connection and recordset objects freeing up resources 
$rs->Close();
$conn->Close();

$rs = null;
$conn = null;
?>

However, none of these codes work (on my server anyway). I received the following error messages:

Error 1:

Error 2:

Error 3:

What am I doing wrong? How can I make only one of the codes above work?

 

Is the site on the same server or is it on another server?

 

The site is hosted on the same server as the one that hosts SQL Server.
