Issue

I use curl to get the website content, but the encoding of this page is gbk. Some characters are unreadable. The results are shown below.

<html>
<head>
    <meta charset="gbk">
    <meta charset="GBK" />
    <title>����ΪP40 8GB/128GB/ȫ��ͨ/5G���������Ϊ P40 8GB/128GB/ȫ��ͨ/5G���ֻ�����_���_����_����-ZOL�йش�����</title>

Solution

With mb_convert_encoding method, we can convert character encoding. It need mbstring extension, add --enable-mbstring when configure php. It Supports Character Encodings.

$url = "http://detail.zol.com.cn/1317/1316635/param.shtml";
$curl = curl_init();
...

$html = curl_exec($curl);
$utf8Body = mb_convert_encoding($html, 'utf-8','GBk');

After convert encoding, the content is normal.

<html>
<head>
    <meta charset="gbk">
    <meta charset="GBK" />
