连接到 PHP 的 SQL 服务器：无法建立连接

Question

Connection could not be established. Array ( [0] => Array ( [0] => 08001 [SQLSTATE] => 08001 [1] => 10061 [code] => 10061 [2] => [Microsoft][ODBC Driver 11 for SQL Server]TCP Provider: No connection could be made because the target machine actively refused it. [message] => [Microsoft][ODBC Driver 11 for SQL Server]TCP Provider: No connection could be made because the target machine actively refused it. ) [1] => Array ( [0] => HYT00 [SQLSTATE] => HYT00 [1] => 0 [code] => 0 [2] => [Microsoft][ODBC Driver 11 for SQL Server]Login timeout expired [message] => [Microsoft][ODBC Driver 11 for SQL Server]Login timeout expired ) [2] => Array ( [0] => 08001 [SQLSTATE] => 08001 [1] => 10061 [code] => 10061 [2] => [Microsoft][ODBC Driver 11 for SQL Server]A network-related or instance-specific error has occurred while establishing a connection to SQL Server.

代码：

<?php
$serverName = "localhost\sqlexpress, 1433"; //serverName\instanceName, portNumber (default is 1433)
$connectionInfo = array( "Database"=>"QLBH", "UID"=>"sa", "PWD"=>"123456");
$conn = sqlsrv_connect($serverName, $connectionInfo);

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

我该如何解决？

Answer 1

 $serverName = "(local)";

$connectionOptions = array("Database"=>"dbname" Username=>Username,PWD=password);



/* Connect using Windows Authentication. */

$conn = sqlsrv_connect( $serverName, $connectionOptions);

if( $conn === false )

      { die( FormatErrors( sqlsrv_errors() ) ); }

connectionOptions 给出数组中的所有连接数据。 sql_connect 只包含两个参数。
