PHP连接MSSQL数据库,原来使用的是MSSQL2000,配置相对简单一点,只需要在php.ini配置文件中修改extension=php_mssql.dll就可以了。现在将数据库升级到了SQL SERVER2008,就需要自己添加PHP对MSSQL连接的驱动扩展SQLSRV了。
1.下载SQLSRV扩展
(1)去官方下载一个SQL Server Driver for PHP的扩展包,我是在这里下载的http://www.microsoft.com/en-us/download/details.aspx?id=20098。
下载驱动程序,下载后安装释放程序,里面有以下文件:
php_pdo_sqlsrv_52_nts.dll
php_pdo_sqlsrv_52_ts.dll
php_pdo_sqlsrv_53_nts_vc6.dll
php_pdo_sqlsrv_53_nts_vc9.dll
php_pdo_sqlsrv_53_ts_vc6.dll
php_pdo_sqlsrv_53_ts_vc9.dll
php_sqlsrv_52_nts.dll
php_sqlsrv_52_ts.dll
php_sqlsrv_53_nts_vc6.dll
php_sqlsrv_53_nts_vc9.dll
php_sqlsrv_53_ts_vc6.dll
php_sqlsrv_53_ts_vc9.dll
SQLServerDriverForPHP.chm(手册,英文够好的话,可以看看,嘿嘿)
SQLServerDriverForPHP_License.rtf
SQLServerDriverForPHP_Readme.htm(自述文件)
2.添加扩展
根据(vc6/vc9)需要选择扩展,我的环境是WAMP(php5.2.6/apache2.2.8),我选用的是php_sqlsrv_52_ts_vc6.dll,php_pdo_sqlsrv_52_ts_vc6.dll这两个文件,复制到wamp安装目录下的ext目录下,我的ext目录是在wamp/bin/php/php5.2.6/ext/
3.配置php.ini
(1)在php.ini的Dynamic Extensions中添加如下两条扩展:
extension=php_sqlsrv_52_ts_vc6.dll
extension=php_pdo_sqlsrv_52_ts_vc6.dll
(2)将;extension=php_pdo.dll前面的;去掉,开启pdo连接扩展
(3)重新启动apache
4.连接数据库(pdo连接)
<?php $servern="SFKFK27EL8FJ\SQLTRY"; $coninfo=array("Database"=>"try2","UID"=>"sa","PWD"=>"123"); $conn=sqlsrv_connect($servern,$coninfo) or die ("连接失败!"); $val=sqlsrv_query($conn,"select * from usertable"); while($row=sqlsrv_fetch_array($val)){ echo $row[1]."<br />"; } sqlsrv_close($conn); ?>
链接示例:
mssql_lib.php文件如下:
<?php class DB { var $con = null; function __construct($dbhost,$dbuser,$dbpass,$dbname) { $connectionInfo = array("UID"=>$dbuser,"PWD"=>$dbpass,"Database"=>$dbname); $this->con = sqlsrv_connect($dbhost,$connectionInfo); } function query($sql){ $result = sqlsrv_query($this->con, $sql); } function getRow($sql){ $result = sqlsrv_query($this->con, $sql); $arr = array(); while($row = sqlsrv_fetch_array($result)) { $arr[] = $row; } return $arr[0]; } function getAll($sql){ $result = sqlsrv_query($this->con, $sql); $arr = array(); while($row = sqlsrv_fetch_array($result)) { $arr[] = $row; } return $arr; } function __destruct() { unset($con); } }
test.php页面如下:
$db = new DB(DB_HOST, DB_USER, DB_PASS, DB_NAME); $sql = "select * from crm_order_batch where (status=0 or status is null) and lock_id is not null "; $orders_add_list = $db->getAll($sql);
