<?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"
