一、安装SQL Driver for PHP 2.0
下载SQL Driver for PHP2.0,地址是:http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx
解压后根据PHP的版本选择对应的.dll文件,放入PHP扩展目录。PHP版本对应的.dll是(在压缩包内的SQLSRV_Readme.html里):
Driver file
PHP version
Thread safe?
Use with PHP .dll
php_sqlsrv_53_nts_vc6.dll
php_pdo_sqlsrv_53_nts_vc6.dll
5.3
no
php5.dll
php_sqlsrv_53_nts_vc9.dll
php_pdo_sqlsrv_53_nts_vc9.dll
5.3
no
php5.dll
php_sqlsrv_53_ts_vc6.dll
php_pdo_sqlsrv_53_ts_vc6.dll
5.3
yes
php5ts.dll
php_sqlsrv_53_ts_vc9.dll
php_pdo_sqlsrv_53_ts_vc9.dll
5.3
yes
php5ts.dll
php_sqlsrv_52_nts_vc6.dll
php_pdo_sqlsrv_52_nts_vc6.dll
5.2
no
php5.dll
php_sqlsrv_52_ts_vc6.dll
php_pdo_sqlsrv_52_ts_vc6.dll
5.2
yes
php5ts.dll
接下来修改PHP.ini文件,添加以下几条命令(以PHP5.2,Thread Safe版本为例):
extension=php_pdo.dll extension=php_sqlsrv_52_ts_vc6.dll extension=php_pdo_sqlsrv_52_ts_vc6.dll 完成后重启Apache,通过phpinfo();查看安装结果。如果出现PDO_sqlsrv一栏,就说明驱动安装成功。 二、连接数据库 连接SQL Server 2008有两种方式,即Windows认证和Windows与SQL的混合认证。对于两种认证,使用的连接方式也有所不同。 使用Windows认证连接时,代码为: <?php try { $conn = new PDO( "sqlsrv:Server=服务器IP地址;Database=数据库名",NULL, NULL); $conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION ); } catch( PDOException $e ) { die( "Error connecting to SQL Server".$e->getMessage() ); } echo "Connected to SQL Server/n"; $query = 'select * from 表名'; $stmt = $conn->query( $query ); while ( $row = $stmt->fetch( PDO::FETCH_ASSOC ) ){ print_r( $row ); } ?>
使用混合认证模式时,代码为:
<?php
$serverName = "服务器IP地址";
$database = "数据库名";
// Get UID and PWD from application-specific files.
$uid = file_get_contents("C:/AppData/uid.txt");
$pwd = file_get_contents("C:/AppData/pwd.txt");
try {
$conn = new PDO( "sqlsrv:server=$serverName;Database = $database", $uid, $pwd);
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
}
catch( PDOException $e ) {
die( "Error connecting to SQL Server".$e->getMessage() );
}
echo "Connected to SQL Server/n";
$query = 'select * from 表名';
$stmt = $conn->query( $query );
while ( $row = $stmt->fetch( PDO::FETCH_ASSOC ) ){
print_r( $row );
}
// Free statement and connection resources.
$stmt = null;
$conn = null;
?>
在使用混合认证时,微软建议尽量避免使用“sa”作为用户ID,而且用户名和密码不要直接出现在代码中,而是写入服务器上某一文件内,以保证数据库的安全。
