$recordSet[$index]

Up: class RecordSet

For the most part an instance of RecordSet can be treated like an array. In particular you can retrieve a class instance using a subscript, which is in most cases the primary key of the class. You can create a new instance of a class and store it into the RecordSet using a subscript. You can delete an entry from the RecordSet using unset($recordSet[$index]), although that just removes it from the RecordSet, not from the database. And, as noted previously you can ask how many entries there are in the RecordSet using the count function.

Examples:

$countries	  = new RecordSet('Countries');
$canada		  = $countries['CA'];
$BIOT		  = $countries['IO'];
unset($countries['IO']);	// remove from RecordSet
$BIOT->delete();	        // actually delete the record
$BIOT		  = new Country(array('code'	=> 'IO',
				      'name'	=> 'Diego Garcia');
$BIOT->save();		        // actually add record to database
$countries['IO']  = $BIOT;	// add to RecordSet

Note that the RecordSet is out of alphabetical order by name after these changes.
