<?php
$myServer = "host_name";
$myUser = "user_name";
$myPass = "password";
$myDB =  "database_name";

//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 col1, col2, col3, .... , coln FROM table_name";

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

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

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

$contents="<table border='1'>";

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

$contents.="</table>";

$file="File_name.xls";
$test="<table border=1><tr><td>Cell 1</td><td>Cell 2</td></tr></table>";
header("Content-type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=File_name".date('Y-m-d').".xls");
echo $contents;

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

$rs = null;
$conn = null;
