str_replace with "grave" accent

Question

I'm developing a web and I want to print some information from DB. I have found the problem that information with "grave" accent it is not possible to convert to upper case.

For example, I have the following information: John Seràn Mollò and I need to convert it to upper case. This should be the result: JOHN SERÀN MOLLÒ

I'm trying the following code:

            $filtre = array("&agrave", "&egrave", "&ograve");
            $modificacions = array("a", "e", "o");
            $phrase = str_replace($filtre, $modificacions, $vols[$i]['crew']);
            var_dump($phrase);
            echo strtoupper($phrase); ?>

In that case, the result should be JOHN SERAN MOLLO (without the accents), but I get this: JOHN SERàN MOLLò.

What I'm doing bad? How can I get JOHN SERAN MOLLO (without accents) or, if it's possible, how can I could get JOHN SERÀN MOLLÒ (accents in upper case).

`à` and `a` is not the same. add `à` to the `$modifications` array — Saeed M., Apr 13 '18 at 10:53
Why don't you replace directly `à` with `À` etc... ? (if encoding is consistent in your appli) — Déjà vu, Apr 13 '18 at 10:54
Why are you comparing entities to a string? Surely, that's the reason it doesn't work. — Script47, Apr 13 '18 at 10:54
I know, but if I do it I get à. I have explained below the code — msabate, Apr 13 '18 at 10:55

@Script47 I have the same explanation why is not working, but how can I fix it? — msabate, Apr 13 '18 at 10:55
*How can I get JOHN SERAN MOLLO (without accents)* vs *how can I could get JOHN SERÀN MOLLÒ (accents in upper case).* - Which one do you want or do you want both? Please clarify. — Script47, Apr 13 '18 at 10:56
@Script47 I prefer to get the second one, but it doesn't matter if I can get the first one because the second one is not possible — msabate, Apr 13 '18 at 10:58

If your installation has the mbstring extension loaded (most do, in my experience), you should be able to use mb_strtoupper, e.g.

echo mb_strtoupper($phrase);

This will use the default internal encoding by default, so should be all you need, but you may also need to provide a second argument to specify the string encoding.

If the function isn't available, there's a polyfill available here: https://github.com/symfony/polyfill-mbstring

Use strtoupper() function or mb_strtoupper() function. Woohaa just try this... Have a good Day... Seeya...

<?php

setlocale(LC_CTYPE, 'de_DE.UTF8');

echo strtoupper('Umlaute äöü in uppercase'); // outputs "UMLAUTE äöü IN UPPERCASE"
echo mb_strtoupper('Umlaute äöü in uppercase', 'UTF-8'); // outputs "UMLAUTE ÄÖÜ IN UPPERCASE"

?>
