自从php5.3之后系统就不支持mssql_connect这个函数连接了,以前我也讲可以使用com接口来实现,现在我再介绍解决php5.3不能连接mssql数据库另一方法.

windows系统下,PHP5.3以上的版本已经不支持mssql扩展.

首先http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx 点击 get it 下载SQLSRV20.EXE。

将文件解压到php的扩展文件夹ext下,打开php.ini在结尾添加:

[PHP_PDO_SQLSRV] 

extension=php_pdo_sqlsrv_53_nts_vc6.dll 

[PHP_SQLSRV] 

extension=php_sqlsrv_53_nts_vc6.dll 

保存后重启apache即可,附上简单的php连接的例子,代码如下:

<?php
$serverName = "(127.0.0.1)";
$connectionInfo = array(
    "UID" => "root",
    "PWD" => "root2010",
    "Database" => "master"
);
$conn = sqlsrv_connect($serverName, $connectionInfo);
//开源代码phprm.com
if ($conn) {
    echo "Connection established.n";
} else {
    echo "Connection could not be established.n";
    die(print_r(sqlsrv_errors() , true));
}
Copy after login

我使用的是wamp5.1集成安装包,在windows server 2008上面做的测试,php5.4以上版本测试没有成功.

如果使用这个扩展连接Sql server 2005以上版本的sql server(如sql server 2008),你还需要在机器上先安装 SQL Server Native Client :http://download.microsoft.com/download/0/E/6/0E67502A-22B4-4C47-92D3-0D223F117190/sqlncli.msi

这个扩展为php新增了一系列sqlsrv_开头的函数,函数参考如下:

sqlsrv_begin_transaction 
sqlsrv_cancel 
sqlsrv_client_info 
sqlsrv_close 
sqlsrv_commit 
sqlsrv_configure 
sqlsrv_connect 
sqlsrv_errors 
sqlsrv_execute 
sqlsrv_fetch 
sqlsrv_fetch_array 
sqlsrv_fetch_object 
sqlsrv_fetch_metadata 
sqlsrv_free_stmt 
sqlsrv_get_config 
sqlsrv_get_field 
sqlsrv_has_rows 
sqlsrv_next_result 
sqlsrv_num_fields 
sqlsrv_num_rows 
sqlsrv_prepare 
sqlsrv_query 
sqlsrv_rollback 
sqlsrv_rows_affected 
sqlsrv_send_stream_data 
sqlsrv_server_info
Copy after login

更多详细的说明可以在刚才的自解压的文件中有个 SQLServerDriverForPHP.chm 帮助文件中可以找到打开后点击API Reference节点.

另外看一种odb连接方式,代码如下:

$dbhost = "; 
$dbuser = "; //你的mssql用户名 
$dbpass = "; //你的mssql密码 
$dbname = "; //你的mssql库名 
$connect=odbc_connect("Driver={SQL Server};Server=$dbhost;Database=$dbname","$dbuser","$dbpass"); 
$sql="select * from content"; 
$exec=odbc_exec($connect,$sql); 
while($row = (odbc_fetch_array($exec))) 
{ 
$row[&#39;id&#39;]   //?取字段值 
… 
}
Copy after login
