How to move the internal pointer of an array in PHP?

Every PHP array has an internal pointer that points to one element. You can move it with these functions:

Function	What it does
current()	Returns the element where the pointer is now
key()	Returns the key of the current element
next()	Moves the pointer one step forward
prev()	Moves the pointer one step back
reset()	Moves the pointer to the first element
end()	Moves the pointer to the last element

<?php
$fruits = ["apple", "banana", "cherry"];

echo current($fruits) . "<br>";
echo next($fruits) . "<br>";
echo next($fruits) . "<br>";
echo prev($fruits) . "<br>";
echo reset($fruits) . "<br>";
echo end($fruits);
?>

Output:

When the pointer goes outside the array, next() and prev() return false.
