<?php
$array = array('1' => 'one',
'2' => 'two',
'3' => 'three');
$arrayobject = new ArrayObject($array);
for($iterator = $arrayobject->getIterator();
$iterator->valid();
$iterator->next()) {
echo $iterator->key() . ' => ' . $iterator->current() . "\n";
}
?>
The above example will output:
1 => one
2 => two
3 => three
ArrayIterator
