Question

我尝试使用sqlsrv_connect()函数使用PHP连接到2005 Microsoft SQL数据库。唉，函数返回false，我不知道为什么。

<?php
$myServer = "MAZE.jpc.wa.edu.au.local";
$myUser = "myUsername";
$myPass = "myPassword";
$myDB = "John Paul College";
$connectionInfo = array("Database"=>$myDB, "UID" => $myUser, "PWD" => $myPass);

$conn = sqlsrv_connect($myServer, $connectionInfo); //returns false
if( $conn === false )
{
    echo "failed connection";
}

$sql = "SELECT name FROM users WHERE name= 'admin'";
$stmt = sqlsrv_query($conn,$sql);
if(sqlsrv_fetch($stmt) ===false)
{
    echo "couldn't fetch data"; 
}
$name = sqlsrv_get_field($stmt,0);
echo $name;
sqlsrv_close( $conn );
?>

有谁知道为什么我无法连接？感谢。

编辑。

好的，好吧，我能够提出错误信息，感谢其他人回答，其中说明了

我不完全确定如何解决这个问题。我使用XAMPP作为我的测试网络服务器，php版本5.3和以下.dll php_sqlsrv_53_ts_vc6.dll 和 php_pdo_sqlsrv_53_ts_vc6.dll

我建议您使用sqlsrv_errors（）显示连接错误。请参阅以下实施。

<?php
   $serverName = "serverName\sqlexpress"; //serverName\instanceName

   // Since UID and PWD are not specified in the $connectionInfo array,
   // The connection will be attempted using Windows Authentication.
   $connectionInfo = array( "Database"=>"dbName");
   $conn = sqlsrv_connect( $serverName, $connectionInfo);

   if( $conn ) {
     echo "Connection established.<br />";
   }else{
     echo "Connection could not be established.<br />";
     die( print_r( sqlsrv_errors(), true));
   }
?>

Answer 2

下载SQL Native Client，如错误消息所示。这与SQL Server分开，并且要求此驱动程序正常工作。在IIS环境中构建sqlsrv实现的经验教训

通过sqlsrv_connect（） - PHP连接到mssql数据库
