<?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"
