在php中替换multibyte utf8字符

Question

I am trying to preg_replace the multibytecharacter for euro in UTF (shown as ⬠in my html) to a "$" and the * for an "@"

$orig = "2 **** reviews  ⬠19,99 price";
$orig = mb_ereg_replace(mb_convert_encoding('€', 'UTF-8', 'HTML-ENTITIES'), "$", $orig);
$orig = preg_replace("/[\$\;\?\!\{\}\(\)\[\]\/\*\>\<]/", "@", $orig);
$a = htmlentities($orig);
$b = html_entity_decode($a);

The "*" are being replaced but not the "â¬" .......

Also tried to replace it with

$orig = preg_replace("/[\xe2\x82\xac]/", "$", $orig);

Doesn't convert either....

Another plan which didnt work:

$orig= mb_ereg_replace(mb_convert_encoding('€', 'UTF-8', 'HTML-ENTITIES'), "$", $orig);

Brrr someone knows how to get rid of this utf8 euro character:

echo html_entity_decode('€');

(driving me nuts)

Pasting my comment here as an answer so you can mark it!

Wouldn't

str_replace(html_entity_decode('€'), '$', $source)

work?
