This is a first attempt but the general idea is that the regular
expression matching is done in one operation and then str_replace() is
called only as many times as required instead of once for every line in
your list. Also, str_replace() is faster than ereg_replace().
<?php
$replace = array(
"ñ" => "n",
"á" => "a",
"é" => "e",
"í" => "i",
"ó" => "o",
"ú" => "u"
);
$link = "ssrsrsrsóererrereísddósdssú";
if (preg_match_all("/(".join("|", array_keys($replace)).")/", $link,
$matches)) {
$matches = array_unique($matches);
foreach ($matches[0] as $match) {
$link = str_replace($match, $replace[$match], $link);
}
}
echo $link;
?>
