Example #1 Iterating a MultipleIterator
<?php
$people = new ArrayIterator (array( 'John' , 'Jane' , 'Jack' , 'Judy' ));
$roles = new ArrayIterator (array( 'Developer' , 'Scrum Master' , 'Project Owner' ));
$team = new MultipleIterator ( $flags );
$team -> attachIterator ( $people , 'person' );
$team -> attachIterator ( $roles , 'role' );
foreach ( $team as $member ) {
print_r ( $member );
}
?>
Output with $flags = MIT_NEED_ALL|MIT_KEYS_NUMERIC
Array ( [0] => John [1] => Developer ) Array ( [0] => Jane [1] => Scrum Master ) Array ( [0] => Jack [1] => Project Owner )
Output with $flags = MIT_NEED_ANY|MIT_KEYS_NUMERIC
Array ( [0] => John [1] => Developer ) Array ( [0] => Jane [1] => Scrum Master ) Array ( [0] => Jack [1] => Project Owner ) Array ( [0] => Judy [1] => )
Output with $flags = MIT_NEED_ALL|MIT_KEYS_ASSOC
Array ( [person] => John [role] => Developer ) Array ( [person] => Jane [role] => Scrum Master ) Array ( [person] => Jack [role] => Project Owner )
Output with $flags = MIT_NEED_ANY|MIT_KEYS_ASSOC
Array ( [person] => John [role] => Developer ) Array ( [person] => Jane [role] => Scrum Master ) Array ( [person] => Jack [role] => Project Owner ) Array ( [person] => Judy [role] => )
