PHP iconv方法

string iconv ( string $in_charset , string $out_charset , string $str )

iconv — Convert string to requested character encoding

php  manual iconv方法的原话。

一般的情况下，我使用这个方法，都是这样使用：

   If you append the string //TRANSLIT to out_charset transliteration is activated. This means that when a character can't be represented in the target charset, it can be approximated through one or several similarly looking characters. If you append the string //IGNORE, characters that cannot be represented in the target charset are silently discarded. Otherwise, str is cut from the first illegal character and an E_NOTICE is generated.
