What role does authentication mode (Mixed-Mode) play in resolving connection problems between PHP and MSSQL?

When connecting PHP to MSSQL, using Mixed-Mode authentication can help resolve connection problems by allowing both Windows Authentication and SQL Server Authentication methods to be used. This can be particularly useful if there are issues with authentication mismatches between PHP and MSSQL. By enabling Mixed-Mode authentication, you can ensure that the appropriate authentication method is used to establish a successful connection. 

$serverName = "your_server_name";
$connectionOptions = array(
    "Database" => "your_database_name",
    "Uid" => "your_username",
    "PWD" => "your_password",
    "Authentication" => SQLSRV_SQL_AUTHENTICATION,
);

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

if($conn) {
    echo "Connected successfully";
} else {
    echo "Connection could not be established";
}
