php有專門的sql server操作函數(shù)，舉個(gè)簡(jiǎn)單的例子，是查詢的
$serverName?=?"localhost";?//數(shù)據(jù)庫(kù)服務(wù)器地址
$uid?=?"root";?//數(shù)據(jù)庫(kù)用戶名
$pwd?=?"123456";?//數(shù)據(jù)庫(kù)密碼
$connectionInfo?=?array("UID"=$uid,?"PWD"=$pwd,?"Database"='databasename');
$conn?=?sqlsrv_connect(?$serverName,?$connectionInfo);
if(?$conn?==?false){
echo?"連接數(shù)據(jù)庫(kù)失敗！";
die(?print_r(?sqlsrv_errors(),?true));
}
$sql?=?"select?*?from?user";
$query?=?sqlsrv_query(?$conn,?$sql?,?array(),?array(?"Scrollable"?=?SQLSRV_CURSOR_KEYSET?));
$num_rows?=?sqlsrv_num_rows($query);
if($num_rows??0){
while?($row?=?sqlsrv_fetch_array($query)){
echo?$row['aaaa'];
}
}
其它的操作也同理，舉一反三
