Использование

$Table = new Table();
$Table->__construct( $args );
$args(массив)
Supported arguments:
php table – the name of the database table fields – an array of columns to get from the table, '*' is a valid value and the default where – conditions for filtering rows. Supports two formats: = string – this will be the where clause = array – each element is treated as a condition if it's positional, or as column => value if it's a key/value pair. In the latter case the value is automatically quoted and escaped append - add arbitrary extra SQL
