由浓汤和佩卡的建议去,我写道:curl_exec_utf8
/** The same as curl_exec except tries its best to convert the output to utf8 **/
function curl_exec_utf8($ch) {
$data = curl_exec($ch);
if (!is_string($data)) return $data;
unset($charset);
$content_type = curl_getinfo($ch, CURLINFO_CONTENT_TYPE);
/* 1: HTTP Content-Type: header */
preg_match('@([\w/+]+)(;\s*charset=(\S+))[email protected]', $content_type, $matches);
if (isset($matches[3]))
$charset = $matches[3];
/* 2: <meta> element in the page */
if (!isset($charset)) {
preg_match('@<meta\s+http-equiv="Content-Type"\s+content="([\w/]+)(;\s*charset=([^\s"]+))[email protected]', $data, $matches);
if (isset($matches[3])) {
$charset = $matches[3];
/* In case we want do do further processing downstream: */
$data = preg_replace('@(<meta\s+http-equiv="Content-Type"\s+content="[\w/]+\s*;\s*charset=)([^\s"]+)@i', '$1utf-8', $data, 1);
}
}
/* 3: <xml> element in the page */
if (!isset($charset)) {
preg_match('@<\?xml.+encoding="([^\s"]+)@si', $data, $matches);
if (isset($matches[1])) {
$charset = $matches[1];
/* In case we want do do further processing downstream: */
$data = preg_replace('@(<\?xml.+encoding=")([^\s"]+)@si', '$1utf-8', $data, 1);
}
}
/* 4: PHP's heuristic detection */
if (!isset($charset)) {
$encoding = mb_detect_encoding($data);
if ($encoding)
$charset = $encoding;
}
/* 5: Default for HTML */
if (!isset($charset)) {
if (strstr($content_type, "text/html") === 0)
$charset = "ISO 8859-1";
}
/* Convert it if it is anything but UTF-8 */
/* You can change "UTF-8" to "UTF-8//IGNORE" to
ignore conversion errors and still output something reasonable */
if (isset($charset) && strtoupper($charset) != "UTF-8")
$data = iconv($charset, 'UTF-8', $data);
return $data;
}

Ooohh甜美!当我找到时间的时候我会试驾这个。 – 2010-03-25 10:41:12
感谢分享,你救了我的命! :D – 2016-06-20 18:37:01
做得很好,但如果我们在下游进行一些进一步处理,我们希望在我们去的时候修复和标签。我冒昧地更新你的代码。 – DomQ 2018-01-08 17:35:57
