What is the best way to retrieve field properties such as encoding, length, and field type from a MSSQL database using PHP?

To retrieve field properties such as encoding, length, and field type from a MSSQL database using PHP, you can use the sqlsrv_field_metadata function provided by the SQL Server Driver for PHP. This function returns an array of field metadata for a specified query result field. You can then access the properties such as encoding, length, and field type from this array. 

<?php
$serverName = "your_server_name";
$connectionOptions = array(
    "Database" => "your_database_name",
    "Uid" => "your_username",
    "PWD" => "your_password"
);

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

if($conn) {
    $sql = "SELECT * FROM your_table_name";
    $stmt = sqlsrv_query($conn, $sql);

    $fieldMetadata = sqlsrv_field_metadata($stmt);
    foreach($fieldMetadata as $field) {
        echo "Field Name: " . $field["Name"] . "<br>";
        echo "Encoding: " . $field["Encoding"] . "<br>";
        echo "Length: " . $field["Size"] . "<br>";
        echo "Field Type: " . $field["Type"] . "<br><br>";
    }

    sqlsrv_free_stmt($stmt);
    sqlsrv_close($conn);
} else {
    die(print_r(sqlsrv_errors(), true));
}
?>
