Regex to combine accented characters

I have the following PHP code:

$search = "foo bar que";
$search_string = str_replace(" ", "|", $search);

$text = "This is my foo text with qué and other accented characters.";
$text = preg_replace("/$search_string/i", "<b>$0</b>", $text);

echo $text;

Obviously, que does not match qué. How can i change this? Is there any way to preg_replaceignore all accents?

Characters to match (Spanish):

á,Á,é,É,í,Í,ó,Ó,ú,Ú,ñ,Ñ

I do not want to replace all characters with an accent before applying the regular expression, because the characters in the text must remain unchanged:

"This is my text foo with qué and other accented characters."

but not

"This is my text foo with que and other accented characters."

:

$vowel_replacements = array(
    "e" => "eé",
    // Other letters mapped to their other versions
);

preg_match - :

foreach ($vowel_replacements as $vowel => $replacements) {
    str_replace($search_string, "$vowel", "[$replacements]");
}

If I remember my right to PHP, this should replace your vowels with the character class of their accented forms - which will keep it in place. It also allows you to easily change the search bar; You do not need to forget about replacing vowels with character classes. All you need to remember is to use the non-accumulated form in the search bar.

(If there is any special syntax, I forget that it does this without foreach, comment and let me know.)
