How to implement PHP connection to SQLServer2005 (attached ntwdblib.dll download)_PHP tutorial

php连接sql2005的问题,现在整合,同时把FAQ整合上.

我前面写的教程:

连接前配置系统:

1.检查文件 php5.2.5/ntwdblib.dll 默认下面有一个,不能连接再替换.

下载正确版本的 ntwdblib.dll (2000.80.194.0)，地址： http://www.jb51.net/dll/ntwdblib.dll.html

2.配置php

a、打开php.in将extension=php_mssql.dll的注释符号去掉。

b、打开php.in将mssql.secure_connection = Off改为on。

c、将php_mssql.dll拷贝到php.in中extension_dir 指定的目录或者系统system32目录下。(php_mssql.dll在php的压缩安装包中有)。

以上步骤完成后需要重启apache。

注意：实际使用中发现 如果通过php压缩文件手工安装php到iis下，必须重启机器而不仅仅是iis。

3.配置sqlserver 
a. 运行 SQL Server 配置管理器：SQL Server Configuration Manager，打开协议 Protocols 
b. 允许命名管道 "named pipes" 和 "tcp/ip" 
c. 右键点击 "tcp/ip"，打开属性 Properties 标签 "IP addresses" 
d. 在 TCP 动态端口 "TCP Dynamic Ports" 填入 1433 
e. 重启 SQL Server

-----------------------------------------------------------------------------------------------  
4.使用以下方式连接MS SQL Server 2005： 
代码如下：

//链接数据库 
 $conn=mssql_connect('localhost','sa','123456'); 
   mssql_select_db('gu_dde',$conn); 
//query语句   
 $Query="select * from dde_top"; 
 $AdminResult=mssql_query($Query); 
//输出结果 
 $Num=mssql_num_rows($AdminResult); 
 for($i=0;$i 
   { 
 $Row=mssql_fetch_array($AdminResult); 
 echo($Row[1]); 
 echo("
"); 
   }   
?>

输入http://127.0.0.1

-----------------------------------------------------------------------

5.FAQ常见问题:

1报错:

Fatal error: Call to undefined function mssql_connect()

解决:

使用MSSQL_系列函数 
    要使用这两种都需要在php.ini进行设定：  
   (1)允许 DCOM，需要将php.ini中的 ;com.allow_dcom=TRUE前的分号";"去掉。 
   (2)使用MSSQL扩展，需要php.ini中的 ;extension=php_mssql.dll前的分号";"去掉。(关键)  
   (3)确认extension_dir为正确路径,以本机为例：extension_dir = "c:/AppServ5.2.6/php/ext"。  
   (4)如果仍然机器报错说找不到c:/AppServ5.2.6/php/ext/php_mssql.dll但明明存在这个文件。 
   解决方法：将php_mssql.dll,ntwdblib.dll拷贝到系统目录/system32下重启测试。。 
    (注:上面两个dll文件不在相同目录下，我的为c:/AppServ5.2.6/php/ext/php_mssql.dll；c:/AppServ5.2.6/php/ntwdblib.dll) 
    另外设置好了后记得重启服务器哦。

2.mssql_connect() Unable to connect to server

确认SQLServer2005服务器正常.检查 TCP/IP已经启用

同时右键查看属性:

已经启用是否选择是

确认服务器正确之后,再确认ntwdblib.dll 文件位置是否放到了 c:/windows/system32下

同时要保证ntwdblib.dll 这个文件的版本和sqlserver的版本对应:

下面是对应关系:

2.ntwdblib.dll 版本为 2000.2.8.0 是 对应 SqlServer2000(这个是网络查资料和猜测,没装2000)

2.ntwdblib.dll 版本为 2000.80.194.0 是 对应 SqlServer2005(这个是用实验证明可以用,本人就是用笔记本装了2005)

3.ntwdblib.dll version is 2000.80.2039 is corresponding to SqlServer2008 (this is a guess that 2008 is not installed)

6. Other questions:

If php apache Sql Server2000 is on the same machine, there will be basically no problem accessing it.

If the Sql Server2000 and PHP machines are separated, you need to confirm that the machine name of the machine where the sqlserver is located can be pinged. If it cannot be passed, modify the hosts file under /system32/drivers/etc of the machine where the php server is located and add a line to the machine where the sqlserver is located. The machine ip is the machine name of the machine where sqlserver is located.

If you still cannot access it, you need to confirm whether the machine where php is located has a secret conversion to mdac. How about simply installing the sqlserver client.

The problem is solved as follows:

1. Download two files php_mssql.dll and ntwdblib.dll

php_mssql.dll If this is not copied to c:/windows/system32, it will easily appear

Pay attention to the version of this file ntwdblib2093.dll, otherwise it will be very frustrating later.
