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