Sources

You may export data from various sources:

• PHP Array

• CSV

• Doctrine Query (ORM & ODM supported)

• PDO Statement

• PHP Iterator instance

• PHP Iterator with a callback on current

• XML

• Excel XML

• XLSX (SpreadsheetML format for Microsoft Excel)

• Sitemap (Takes another iterator)

• Chain (can aggregate data from several different iterators)

You may also create your own. To do so, create a class that implements \Iterator.
