escaping column name with PDO

Question

I have a function that\'s like

function getInfoById($id, $info) {

}

the idea is to have a query be \"SELECT $info FROM table WHERE i

Answer 1

What about using quote and substr.

$sql = 'SELECT * FROM table WHERE `' . substr($db->quote($field), 1, -1) . '` = :id';

This will remove the quotes surrounding the escaped field.
