iconv — Convert string to requested character encoding
Performs a character set conversion on the string str from in_charset to out_charset.
The input charset.
The output charset.
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.
The string to be converted.
Returns the converted string 或者在失败时返回 FALSE.
