Question

你好我是新来的，

但是我用sqlsrv创建了2个不同的鳕鱼，它连接到sql server 2012

但是当我用mysqli创建另一个php代码时，它返回错误，任何想法为什么？

sqlsrv的第一个代码：

$connect = array( "UID" => "admin", "PWD" => "admin2017", "Database" => "sunto" );
$link = sqlsrv_connect( "localhost", $connect );
if( $link ) {
     echo "Connection established.<br />";
} else{
     echo "Connection could not be established.<br />";
     die( print_r( sqlsrv_errors(), true ) );
}

使用mysqli_connect的另一个代码：

<?php


$hostname = "localhost";
$username = "admin";
$password = "admin2017";

$databaseName = "sunto";

$dbConnected = mysqli_connect($hostname, $username, $password);

$dbSelected = mysqli_select_db($dbConnected, $databaseName);


?>

显示以下错误!!

警告：mysqli_connect（）:( HY000 / 2002）：无法建立连接   因为目标机器主动拒绝它。在   第10行的C：\ Apache24 \ htdocs \ index3.php

警告：mysqli_select_db（）期望参数1为mysqli，boolean   在第12行的C：\ Apache24 \ htdocs \ index3.php中给出

在php.ini（xampp-＆gt; php-＆gt; php.ini）配置文件中查找mysqli。你可以在那个文件中找到; extension = php_mysqli.dll 。取消注释（extension = php_mysqli.dll）这个并尝试下面的代码。

<?php

     @session_start();
     $servername = "localhost";
     $username = "your_username";
     $password = "your_password";
     $dbname = "your_dbname";
     // Create connection
     $conn = new mysqli($servername, $username, $password, $dbname);
     // Check connection
     if ($conn->connect_error) {
     die("Connection failed: " . $conn->connect_error);
     }
?>

sqlsrv连接到sql server whil Mysqli_connect没有
