PHP中iconv函数知识汇总(2)

from_encoding is specified by character code name before conversion. it can be array or string - comma separated enumerated list. If it is not specified, the internal encoding will be used.
 /* Auto detect encoding from JIS, eucjp-win, sjis-win, then convert str to UCS-2LE */
 $str = mb_convert_encoding($str, “UCS-2LE”, “JIS, eucjp-win, sjis-win”);
 /* “auto” is expanded to “ASCII,JIS,UTF-8,EUC-JP,SJIS” */
 $str = mb_convert_encoding($str, “EUC-JP”, “auto”);

例子：

$content = iconv(”GBK”, “UTF-8″, $content); $content = mb_convert_encoding($content, "UTF-8″,"GBK");

php中使用iconv函数时容易忽略的参数

今天在处理抓取内容的时候，当采用iconv进行编码转换的时候，发现结果会中断，猜是字符集的问题，考虑怎么跳过目标字符集不存在的字符，查手册发现iconv的函数只有三个参数，好像不行，然后查网上有人说可以，但是很奇怪怎么实现，最后发现英文描述有说可以加标识到目标编码后面：“TRANSLIT”，很郁闷怎么加呢？原来是先加“//”，真是郁闷，竟然有这样的设计
原型： $txtContent = iconv("utf-8",'GBK',$txtContent);

特殊参数：iconv("UTF-8","GB2312//IGNORE",$data)

两个可选的辅助参数：TRANSLIT和IGNORE ，(其中IGNORE 就是说遇到无法转换的就跳过)。
