請問各位大大，我想架設 iis server + php + mssql
環境是 OS:win10 php版本:7.1.30 mssql版本是 14.0

用PHP連接mssql的時候一直連不上，出現以下訊息

Connection could not be established.

Array ( [0] => Array ( [0] => 28000 [SQLSTATE] => 28000 [1] => 18456 [code] => 18456 [2] => [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]�ϥΪ� 'NT AUTHORITY\IUSR' ���n�J���ѡC [message] => [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]�ϥΪ� 'NT AUTHORITY\IUSR' ���n�J���ѡC ) [1] => Array ( [0] => 28000 [SQLSTATE] => 28000 [1] => 18456 [code] => 18456 [2] => [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]�ϥΪ� 'NT AUTHORITY\IUSR' ���n�J���ѡC [message] => [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]�ϥΪ� 'NT AUTHORITY\IUSR' ���n�J���ѡC ) )

然後我有安裝ODBC 17，但不知道是否正確，結果於下圖

測試連接mssql的程式碼

$serverName = "DESKTOP-96U7FIF"; //serverName\instanceName

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

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

想請各位高手能幫幫我，這問題已經搞了2天還是沒結果
