无法连接到mssql服务器或sqlsrv没有显示在phpinfo上

i have problem to connect to server, i did all the step from here and i already change php.ini On windows: extension_dir = "D:\xampp\php\ext" but i still cant connect, My PHP Version is 7.2.11 i tried with mssql_connect() and sqlsrv_connect()

here my

`<?php
$servername = "1111";
$username = "user";
$password = "123";
$dbname = "DEV";
$connection = mssql_connect($servername, $username, $password);
if (!$connection) {  die('Not connected : ' . mssql_get_last_message());} 
$db_selected = mssql_select_db($dbname, $connection);
if (!$db_selected) {
  die ('Can\'t use db : ' . mssql_get_last_message());
} else{
echo "success";} ?>`

MSSQL extension for PHP (mssql_ functions) and PHP Driver for SQL Server (sqlsrv_ functions) are two different extensions for PHP.

MSSQL extension is not available anymore on Windows with PHP 5.3 or later, so you need to install PHP Driver for SQL Server. You need to download appropriate version of this driver. For PHP 7.2 - version 5.2 or 5.3 (32-bit or 64-bit also depends on PHP version). Also download and install an appropriate ODBC driver.

Check the configuration with <?php phpinfo();?>. There should be a section with name pdo_sqlsrv (if you use PDO) and/or sqlsrv (without PDO).

Example:

<?php
$server   = '1111';
$database = 'DEV';
$uid      = 'user';
$pwd      = '123';

# SQL Server authentication
#$cinfo = array(
#    "Database" => $database,
#    "UID" => $uid,
#    "PWD" => $pwd
#);

# Windows authentication
$cinfo = array(
    "Database" => $database
);

$conn = sqlsrv_connect($server, $cinfo);
if ($conn === false) {
    echo "Error (sqlsrv_connect): ".print_r(sqlsrv_errors(), true);
    exit;
} else {
    echo "success";
}

sqlsrv_close($conn);
?>
