In MySQL strict mode PHP boolean values produce error

[GoogleCodeExporter]

When you have a MySQL database connection set to STRICT_TRANS_TABLE, the 
database server won't accept the PHP true/false value, it refuses it with the 
following error: "SQLSTATE[HY000]: General error: 1366 Incorrect integer value: 
'' for column 'xy' at row 1".

The error originates from that PHP tries to pass the boolean value as a 
PHP-boolean, but in MySQL such value doesn't exist. So it's necessary to simple 
cast it to integer.

In the mapper's toArray() function (~56. line) I replaced the following:
'<?=$column['field']?>' => $model->get<?=$column['capital']?>(),

to:

<?php $typeCast = $column['phptype'] == 'boolean' ? ' (int)' : '';?>
'<?=$column['field']?>' =><?=$typeCast?> $model->get<?=$column['capital']?>(),

This patch works fine, but it doesn't handle other DB engines or when you need 
boolean values in PHP code (aka. you need the toArray() function not for save 
into the database).
