This is from an old script.  No professional would use the MySQL extension any more, but it can be mapped into the currently supported extensions by following the guidance in this article.  The query and the theory are still accurate.

// GET THE COLUMN NAMES
$sql = "SHOW COLUMNS FROM books";
if (!$res = mysql_query($sql))
{
    $errmsg = mysql_errno() . ' ' . mysql_error();
    echo "<br/>QUERY FAIL: ";
    echo "<br/>$sql <br/>";
    trigger_error($errmsg, E_USER_ERROR);
}
if (mysql_num_rows($res) == 0)
{
    echo "TABLE books HAS NO COLUMNS";
}
else
{
    // MAN PAGE: http://php.net/manual/en/function.mysql-fetch-assoc.php
    while ($show_columns = mysql_fetch_assoc($res))
    {
        $my_columns[] = $show_columns["Field"];
    }
    // SEE THE COLUMN NAMES
    var_dump($my_columns);
}
