Using PDO::FETCH_CLASS with Magic Methods

Question

I have a class that uses magic methods to store properties. Here is a simplified example:

class Foo {
    protected $props;

    public function __construct         


        

Answer 1

The default behavior of PDO is to set the properties before invoking the constructor. Include PDO::FETCH_PROPS_LATE in the bitmask when you set the fetch mode to set the properties after invoking the constructor, which will cause the __set magic method to be called on undefined properties.

$st->setFetchMode(PDO::FETCH_CLASS | PDO::FETCH_PROPS_LATE, 'Foo');

Alternatively, create an instance and fetch into it (i.e. set fetch mode to PDO::FETCH_INTO).
