在 PHP 中使用 curl 获取 unicode 字符

Question

我尝试使用 curl 获取 URL。返回值包含 unicode 字符。 curl 转换为 \u 以获取 unicode 字符。如何使用 curl 获取 unicode 字符？

这是我的代码

<?php
$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.ornagai.com/index.php/api/word/q/test/format/json");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$return=curl_exec($ch);
echo $return;
?>

返回 json 跟随

Answer 1

curl 将获取远程服务器发送的任何内容：它不会解释任何内容，也不会对其获取的数据进行任何修改。

如果 curl 返回的字符中有 \uxxxx 字符，那是因为它们是由远程服务器返回的。

在 JSON 数据中包含 \uxxxx 字符应该不是问题：这是使用 JSON 时应该对 unicode 字符进行编码的方式——参见字符串的定义，http://json.org/

在使用 JSON 数据时，这些应该被 Javascript 正确解释。
