PHP - 将ΓÇô转换为破折号

Question

I found some special characters in my PHP script. One of them is ΓÇô. It's actually a special character of a dash -. How should I convert it back to dash so I can process the string?

Answer 1

I found the answer! It's inspired by this answer

$title = "Hunting, Tactical & Outdoor Optics eCommerce Store ΓÇô $595,000 ΓÇö SOLD";
$title = str_replace(html_entity_decode('–', ENT_COMPAT, 'UTF-8'), '-', $title);
$title = str_replace(html_entity_decode('—', ENT_COMPAT, 'UTF-8'), '-', $title);

Replacing the character right away won't work. html_entity_decode is definitely needed.
