How can I reset an array in PHP?

Sometimes if you are moving through the various elements in an array, you will want to return the pointer to the beginning of the array.

This is easily done with the reset function, like this:
reset($array);

This returns the first element and sets it as the current element.

Here is a little example just to make this technique clear:


<?php

$numbers = array("Item 1","Item 2","Item 3");

next($numbers);

$thisvalue = current($numbers); echo "We are now at $thisvalue\n\n";

$first = reset($numbers);

echo "Back to $first";

?>

Printing:

We are now at Item 2

Back to Item 1
