如何将UTF-8 URL传递给cURL？

Question

I have a table in UTF-8 format. I want to read data from the database and then to curl get content. I pass url in UTF-8 format, but I can't get content. what should I do to solve the problem?

I use below code, but had a problem:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$this->content = curl_exec($ch);
curl_close($ch);

Answer 1

尝试先utf8_encode ，然后urlencode() URL，

$url = urlencode(utf8_encode($url));
