[GoogleCodeExporter]

What steps will reproduce the problem?
1. click save/load
2. choose php-pdo backend
3. click import from DB
4. Or load the php-dbo/index.php directly with ?action=import&database=northwind

What is the expected output? What do you see instead?
Steps 1-3:
Expected output would be the er diagram.  Instead an error message is presented 
in the input/output textarea:
Server response: Internal Server Error

Step 4:
Expected output would be the database diagram presented in xml data.  Instead a 
mysql syntax error is thrown:

Please provide any additional information below.
LayerMYSQL.php has two typos causing these issues:

Problem 1:
public static function Tables() {
...
line 71:  '.self::protect('TABLE_COMMENT').' as '.self::protect('comment').', 
<-- remove trailing comma
...
}

Fix 1:
public static function Tables() {
...
$req = '
SELECT
'.self::protect('TABLE_NAME').' as '.self::protect('name').',
'.self::protect('TABLE_COMMENT').' as '.self::protect('comment').'
FROM '.self::protect('TABLES').'
WHERE
'.self::protect('TABLE_SCHEMA').' = ?
';
...
}

Problem 2:
public static function Keys($table) {
...
line 152: '.self::protect('COLUMN_NAME').' as '.self::protect('column').' <-- 
Add trailing comma
...
}

Fix 2:
public static function Keys($table) {
...
$req = '
SELECT
'.self::protect('TABLE_NAME').' as '.self::protect('table').',
'.self::protect('INDEX_NAME').' as '.self::protect('name').',
'.self::protect('INDEX_TYPE').' as '.self::protect('type').',
'.self::protect('COLUMN_NAME').' as '.self::protect('column').',
'.self::protect('NON_UNIQUE').' as '.self::protect('non_unique').'
FROM '.self::protect('STATISTICS').'
WHERE
'.self::protect('TABLE_SCHEMA').' = ?
ORDER BY '.self::protect('SEQ_IN_INDEX').'
';
...
}

Making these 2 changes fixed the issue for me.

Great tool!
Thanks!
