PHP 5.3 doesn't know how to free a PropelCollection object if it has an attached
Iterator, so this must be done manually to avoid memory leaks.

A PropelOnDemandCollection cannot be exported. Any attempt will result in a PropelExecption being thrown.

Parameters

mixed $parser A PropelParser instance, or a format name ('XML', 'YAML', 'JSON', 'CSV')
boolean $usePrefix (optional) If true, the returned element keys will be prefixed with the model class name ('Article_0', 'Article_1', etc). Defaults to TRUE. Not supported by PropelArrayCollection, as PropelArrayFormatter has already created the array used here with integers as keys.
boolean $includeLazyLoadColumns (optional) Whether to include lazy load(ed) columns. Defaults to TRUE. Not supported by PropelArrayCollection, as PropelArrayFormatter has already included lazy-load columns in the array used here.
