<?php

    $map = array
    (
        '&ntilde;', 'n',
        '&aacute;', 'a',
        '&eacute;', 'e',
        '&iacute;', 'i',
        '&oacute;', 'o',
        '&uacute;', 'u',
    );

    $link =
        str_replace(
            array_keys( $map ), array_values( $map ), $link );

?>

The only way to make it faster is to build the key array and value array
separately, but then the association is not so clear.

Cheers,
Rob.
