Access is not MSSQL, and I'd hardly consider it standard SQL either.
:-) To even connect to it from PHP, I think you'd need to either use a
generic ODBC library or else the COM or DOTNET libraries to use
something like Microsoft's ADO library or similar.
I don't know about the connection details. My point was that querying
the information_schema.columns and the like are the SQL standard way of
querying the database engine to determine the details of the database
and the tables. As I recall, MySQL had quite good tools for doing this,
and PostgreSQL didn't, until the SQL standard way of querying the
database about the database was implemented.

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);
?

A dirty way is to query the table where 1=2 to return no results
select * from table where 1=2
That'll just return an empty result set, as in empty and with no fields

SELECT column_name FROM information_schema.columns WHERE table_name =

I haven't ever seen information_schema in M$ Access.

I guess then you could do something like this:
$row_names = Array();
$query = SELECT TOP 1 * FROM table_name;
$result = mssql_query($query);
while($row = mssql_fetch_array($result))
{
foreach($row as $key = $value)
{
$row_names[] = $key;
}
}
I know it's a little messy there with the double loop, and I'm sure we
can get rid of the while, but I've just woken up, so I'm not too compos
mentis just yet!
