Are there any specific configuration settings in php.ini that need to be adjusted in order to establish a successful connection between PHP and a MSSQL server?

To establish a successful connection between PHP and a MSSQL server, you need to ensure that the `mssql` extension is enabled in your php.ini file. Additionally, you may need to set the correct values for `mssql.secure_connection`, `mssql.charset`, and `mssql.textlimit` based on your server configuration.

// PHP code snippet to establish a connection with MSSQL server
$serverName = "serverName";
$connectionOptions = array(
    "Database" => "dbName",
    "Uid" => "username",
    "PWD" => "password"
);

// Establishes the connection
$conn = sqlsrv_connect($serverName, $connectionOptions);

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