<?php

/**
* Example : rewind();
*/

$arr = new SplFixedArray(5);

$arr[1] = 2;
$arr[4] = "foo";

$a = $arr->key();
var_dump($a);
echo
"<br>";

$arr->next();
$a = $arr->key();
var_dump($a);
echo
"<br>";

$arr->next();
$a = $arr->key();
var_dump($a);
echo
"<br>";

$arr->rewind();
$a = $arr->key();
var_dump($a);
echo
"<br>";
?>

The above example will output:
