What is the significance of setting the PDO::SQLSRV_ATTR_ENCODING attribute when establishing a connection to a SQL Server database in PHP?

Setting the PDO::SQLSRV_ATTR_ENCODING attribute when establishing a connection to a SQL Server database in PHP is significant because it allows you to specify the encoding to be used for data retrieved from the database. This is particularly important when working with multibyte character sets to ensure that data is correctly interpreted and displayed. 

$serverName = "your_server_name";
$connectionOptions = array(
    "Database" => "your_database_name",
    "Uid" => "your_username",
    "PWD" => "your_password",
    PDO::SQLSRV_ATTR_ENCODING => PDO::SQLSRV_ENCODING_UTF8 // Set encoding to UTF-8
);

$conn = new PDO("sqlsrv:Server=$serverName;ConnectionPooling=0", $connectionOptions);
