php: file_get_contents encoding problem
提问by Jamol
My task is simple: make a post request to translate.google.com and get the translation. In the following example I'm using the word "hello" to translate into russian.
我的任务很简单：向 translate.google.com 发出帖子请求并获取翻译。在下面的例子中，我使用“你好”这个词来翻译成俄语。
header('Content-Type: text/plain; charset=utf-8'); // optional
error_reporting(E_ALL | E_STRICT);
$context = stream_context_create(array(
'http' => array(
'method' => 'POST',
'header' => implode("\r\n", array(
'Content-type: application/x-www-form-urlencoded',
'Accept-Language: en-us,en;q=0.5', // optional
'Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7' // optional
)),
'content' => http_build_query(array(
'prev' => '_t',
'hl' => 'en',
'ie' => 'UTF-8',
'text' => 'hello',
'sl' => 'en',
'tl' => 'ru'
))
)
));
$page = file_get_contents('http://translate.google.com/translate_t', false, $context);
require '../simplehtmldom/simple_html_dom.php';
$dom = str_get_html($page);
$translation = $dom->find('#result_box', 0)->plaintext;
echo $translation;
Lines marked as optional are those without which the output is the same. But I'm getting weird characters...
标记为可选的行是那些没有输出相同的行。但我得到了奇怪的字符...
??????
I tried
我试过
echo mb_convert_encoding($translation, 'UTF-8');
But I get
但我得到
Dòé×??
Does anybody know how to solve this problem?
有谁知道如何解决这个问题？
UPDATE:
更新：
- Forgot to mention that all my php files are encoded in UTF-8 without BOM
- When i change the "to" language to "en", that is translate from english to english, it works ok.
- I do not think the library I'm using is messing it up, because I tried to output the whole $page without passing it to the library functions.
- I'm using PHP 5
- 忘了说我所有的 php 文件都是用 UTF-8 编码的，没有 BOM
- 当我将“to”语言更改为“en”时，即从英语翻译成英语，它工作正常。
- 我不认为我使用的库把它搞砸了，因为我试图输出整个 $page 而不将它传递给库函数。
- 我正在使用 PHP 5

Try to see this post if it can help CURL import character encoding problem
试试看这个帖子是否可以帮助CURL导入字符编码问题
Also you can try this snippet (taken from php.net)
你也可以试试这个片段（取自 php.net）
<?php
function file_get_contents_utf8($fn) {
$content = file_get_contents($fn);
return mb_convert_encoding($content, 'UTF-8',
mb_detect_encoding($content, 'UTF-8, ISO-8859-1', true));
}
?>

First off, is your browser set to UTF-8? In Firefox you can set your text encoding in View->Character Encoding. Make sure you have "Unicode (UTF-8)" selected. I would also set View->Character Encoding->Auto-Detect to "Universal."
首先，您的浏览器是否设置为 UTF-8？在 Firefox 中，您可以在 View->Character Encoding 中设置文本编码。确保您选择了“Unicode (UTF-8)”。我还会将 View->Character Encoding->Auto-Detect 设置为“Universal”。
Secondly, you could try passing the FILE_TEXT flag, like so:
其次，您可以尝试传递 FILE_TEXT 标志，如下所示：
$page = file_get_contents('http://translate.google.com/translate_t', FILE_TEXT, $context);

Accept-Charsetis not really that optional. You should specify UTF8 there. Russian characters are not valid in ISO_8859-1
Accept-Charset并不是那么可选。您应该在那里指定 UTF8。俄语字符在 ISO_8859-1 中无效
