PHP连接MSSQL2008/2005数据库(SQLSRV)配置实例_php技巧

分享到:

本文实例讲述了PHP连接MSSQL2008/2005数据库(SQLSRV)配置方法,分享给大家供大家参考。具体方法如下:

PHP连接MSSQL2008/2005数据库与以往的连接mssql2000是不一样的,连接mssql2008/2005是需要自己添加PHP对MSSQL连接的驱动扩展了,而我们常用的hp.ini中的extension=php_mssql.dll扩展只适用连接于MSSQL2000,下面我们就来看看对此的解决办法

1.下载扩展

(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【记得下载后好像是要先安装然后再解压】

(2)您也可以直接从本站下载(我之前下载的,来源于microsoft官方)【点击此处直接下载
将下载下来的rar文件解压后你就会得到一堆的.dll文件

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);
?>

5.例子

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:
//简单调用
$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);

希望本文所述对大家的PHP数据库程序设计有所帮助。
