<?php

/**
 * current() : It returns current element in the SplFixedArray.
 */

$arr = new SplFixedArray(5);

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

var_dump($arr->current());
echo "<br>";

$arr->next();
var_dump($arr->current());
echo "<br>";

$arr->next();
var_dump($arr->current());
echo "<br>";

?>

The output of this will be:

NULL 
int(2) 
string(3) "foo"
