浅析PHP中的字符串编码转换(自动识别原编码)

/**
* 对数据进行编码转换
* @param array/string $data 数组
* @param string $output 转换后的编码
*/
function array_iconv($data,$output = 'utf-8') {
$encode_arr = array('UTF-8','ASCII','GBK','GB2312','BIG5','JIS','eucjp-win','sjis-win','EUC-JP');
$encoded = mb_detect_encoding($data,$encode_arr);//自动判断编码

if (!is_array($data)) {
return mb_convert_encoding($data,$output,$encoded);
}
else {
foreach ($data as $key=>$val) {
if(is_array($val)) {
$data[$key] = array_iconv($val,$input,$output);
} else {
$data[$key] = mb_convert_encoding($data,$encoded);
}
}
return $data;
}
}
