WIN下比較簡單:

1.安裝SQL服務(wù)器并添加PHP的MSSQL擴(kuò)展.
2.使用以下代碼連接并測試

<?php

$myServer = "localhost"; //主機(jī)
$myUser = "sa"; //用戶名
$myPass = "password"; //密碼
$myDB = "Northwind";  //MSSQL庫名

$s = @mssql_connect($myServer, $myUser, $myPass)
or die("Couldn't connect to SQL Server on $myServer");

$d = @mssql_select_db($myDB, $s)
or die("Couldn't open database $myDB");

$query = "SELECT TitleOfCourtesy+' '+FirstName+' '+LastName AS Employee ";
$query .= "FROM Employees ";
$query .= "WHERE Country='USA' AND Left(HomePhone, 5) = '(206)'";

$result = mssql_query($query);
$numRows = mssql_num_rows($result);

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

while($row = mssql_fetch_array($result))
{
echo "<li>" . $row["Employee"] . "</li>";
}

?>

-------------------------------------------------

LINUX下的方法如下:(以TCP/IP 遠(yuǎn)程連接MSSQL)

1.安裝freetds后.配置好.

一般是這樣:

[MSSQL_2000]
host = 192.168.0.25
port = 1433
tds version = 8.0

2.編譯PHP時(shí).加上 --with-mssql=/freetbs的path

3.連接測試:

<?
$msconnect=mssql_connect("MSSQL_2000","sa","");
$msdb=mssql_select_db("Northwind",$msconnect);
$msquery = "select titleofcourtesy,firstname,lastname from employees";
$msresults= mssql_query($msquery);
while ($row = mssql_fetch_array($msresults)) {
       echo "<li>" . $row['titleofcourtesy'] . " " . $row['firstname'] . " " . $row['lastname'] .  "</li>";
}
?>
