我使用ff.代码，但它有一个错误
<?php
$serverName = "MELODY-PC'SQLEXPRESS"; //serverName'instanceName
$connectionInfo = array( "Database"=>"customerdb", "UID"=>"admin", "PWD"=>"reden");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn ) {
echo "Connection established.<br />";
}else{
echo "Connection could not be established.<br />";
die( print_r( sqlsrv_errors(), true));
}
?>Connection could not be established.

if(mssql_connect('server_ip','user','password') === FALSE) die('Error Connecting to MySQL Server.');
但请注意，此函数已被弃用。
您的用户似乎已配置为使用Windows身份验证，但要使用带有凭据（UID和PWD）的sqlsrv_connect()，用户必须具有SQL Server身份验证，而不是Windows身份验证。
此答案显示如何创建SQL Server身份验证用户。
