Twitter API，添加超链接

Question

我正在使用 Twitter API 使用 "statuses/user_timeline" 功能获取我时间线的最后 3 条推文。它抓取推文并发送响应，但我需要在我的网页中为 HTML 注入超链接。问题是 Microsoft 字符正在丢弃链接位置的索引。

[display_url] => artshound.com/event/detail/4…
[indices] => Array
       (
              [0] => 109
              [1] => 131
       )

这是我将超链接插入字符串后的输出：

Answer 1

您可能需要显式设置编码并使用多字节字符串函数：

mb_internal_encoding('UTF-8');
header('Content-type: text/html; charset=UTF-8');
echo mb_substr($text, 0, 109) . '<a href="' . $link . '">' . mb_substr($text, 109, 131-109) . '</a>' . mb_substr($text, 131);
