php連接mysql與mssql 2005數據庫代碼

編輯:關於PHP編程

php教程連接mssql 2005 1.下載以下兩個文件,放入php ext目錄及system32

php_sqlsrv_52_ts_vc6.dll   (線程安全)

php_sqlsrv_52_nts_vc6.dll (非線程安全)

vc6用於apache,vc9用於iis

2.修改php.ini

extension=php_sqlsrv_52_ts_vc6.dll

3.下載sqlncli.msi,微軟官方可以下

安裝的時候提示是sql server 2008的,不過2005也是可以用的。

4.測試代碼

<?php

$servername = "127.0.0.1";
$connectioninfo = array("database"=>"testdb","uid"=>"test","pwd"=>"test");
$conn = sqlsrv_connect($servername, $connectioninfo);

if($conn) {
    echo "connection established.<br>";
} else {
    echo "connection could not be established.<br>";
    die(print_r(sqlsrv_errors(), true));
    exit();
}

$sql = "select * from t_employee";
$result = sqlsrv_query($conn,$sql);
$data = array();
while($row=sqlsrv_fetch_array($result)) {
    $data[] = $row;
}

foreach($data as $p) {
    echo $p['name']."<br>";
}

sqlsrv_close($conn);

echo "<br> done <br>";
echo date("y-m-d h:i:s");

?>
