如何使用xampp将sql server与php连接起来?

I am trying to connect my SQL server with PHP using Xampp. I have already uploaded dll files in the ext folder but I am unable to connect it. My PHP version is 7.2.6. Uploaded dll files are - php_pdo_sqlsrv_72_ts.dll, php_sqlsrv_72_ts.dll. I have written this code to connect my SQL database with PHP-

<?php   
$serverName = "INDO-SERVSQLEXPRESS,1443";  
$uid = "sa";     
$pwd = "XXXXXX";    
$databaseName = "web";  
$connectionInfo = array("UID" => $uid, "PWD" => $pwd, "Database"=>$databaseName);  
$conn = sqlsrv_connect( $serverName, $connectionInfo);  
if( $conn )  
{  
     echo "Connection established.
";  
}  
else  
{  
     echo "Connection could not be established.
";  
     die( print_r( sqlsrv_errors(), true));  
}  
sqlsrv_close( $conn);  
?>     
 
 

我在尝试这个时遇到了这个错误-
