I'm a mess in regular expressions and I make this code:

$link = ereg_replace('ñ','n',$link);
$link = ereg_replace('á','a',$link);
$link = ereg_replace('é','e',$link);
$link = ereg_replace('í','i',$link);
$link = ereg_replace('ó','o',$link);
$link = ereg_replace('ú','u',$link);

I ask if is a way to make those lines into a single one but working as
well as this piece. I'm thinking in increase those lines so will be
wonderful if I can optimize the code.

<?php

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

one mistake, your commas above, between the index and value,
should be a "=>" instead

    );

    $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.
