<?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:

int(0) 
int(1) 
int(2) 
int(0)
