I’m having a problem with htmlentities()

$txt = "árbol";
echo $txt; // outputs: árbol
echo htmlentities($txt); // outputs: árbol (árbol)

The second echo should output árbol (á)

I’m using utf-8:

<meta charset="utf-8">

What’s going on? Thank you!

    You have to set the third parameter of htmlentities() which tells the charset to use. Because of you don’t set it, the default is used and the default is ISO-8859-1, not UTF-8.

    Like htmlspecialchars(), it takes an optional third argument charset which defines character set used in conversion. Presently, the ISO-8859-1 character set is used as the default.

    Just to clarify, this is the function signature:

    string htmlentities ( string $string [, int $flags = ENT_COMPAT | ENT_HTML401 [, string $charset [, bool $double_encode = true ]]] )

    and here you’ll find the official doc: http://php.net/manual/en/function.htmlentities.php
