The information_schema path doesn't appear to work for MS Access.
(Like I said, I'd hardly call it a standard SQL database.) However, I
was able to get a column list using the ODBC library:
<?php
$db_name = 'C:\Path\To\Access\Data\File\MyDatabase';
$dsn = 'Driver={Microsoft Access Driver (*.mdb)};Dbq=' . $db_name . '.mdb';
$table_name = 'MyTable';
$db = odbc_connect($dsn, null, null);
$result = odbc_columns($db, $db_name, "", $table_name);
echo odbc_result_all($result);
?>
