php连接sqlserver2008及以上版本数据库

sqlserver2008及以上版本,微软废弃了对php自带扩展的支持,需要单独安装微软官方提供的驱动

1.安装odbc driver

下载地址: https://www.microsoft.com/en-us/download/details.aspx?id=36434
安装时需给Documents and Settings\<当前登录用户名>\Local Settings\Temp”文件夹的绝对控制权。添加everyone 安装后取消

2.安装Microsoft Drivers for PHP for SQL Server

下载地址 https://www.microsoft.com/en-us/download/details.aspx?id=20098
解压exe文件,拷贝对应版本的dll文件到php对应版本的ext目录,如
php_pdo_sqlsrv_56_nts.dll
php_pdo_sqlsrv_56_ts.dll
php_sqlsrv_56_nts.dll
php_sqlsrv_56_ts.dll

3.修改php.ini

extension=php_pdo_sqlsrv_56_nts.dll
extension=php_sqlsrv_56_nts.dll

4.连接sqlsever示例

sqlsrv_connect取代mssql_connect函数

 

$uid, "PWD"=>$pwd, "Database"=>"gps0310");
$conn = sqlsrv_connect($serverName, $connectionInfo);
if( $conn == false)
{
    echo "连接失败！";
    var_dump(sqlsrv_errors());
    exit;
}
else
{
    echo "链接成功";
}
