<?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"
