Iconv-convert string to requested character encoding (PHP 4 >= 4.0.5, PHP 5)
Mb_convert_encoding-convert character encoding (PHP 4 >= 4.0.6, PHP 5)
Usage:
String mb_convert_encoding (String str, string to_encoding [, mixed from_encoding])
Need to enable mbstring extension library, in php.ini; Extension=php_mbstring.dll in front of; Remove
String Iconv (String in_charset, String out_charset, String str)
Attention:
The second parameter, in addition to specifying the encoding to be converted to, can also add two suffixes://translit and//ignore,
which
Translit automatically converts characters that cannot be converted directly into one or more approximate characters,
IGNORE ignores characters that cannot be converted, and the default effect is to truncate from the first illegal character.
Returns the converted string or FALSE on failure.
Use:
1. Iconv is found to have an error converting the character "-" to gb2312, and if there is no ignore parameter, all strings after that character cannot be saved. Anyway, this
"-" can not be converted successfully, cannot output. Another mb_convert_encoding does not have this bug.
2. Mb_convert_encoding can specify a variety of input codes, which will be automatically recognized according to the content, but the execution efficiency is much worse than the iconv, such as: $str =
Mb_convert_encoding ($str, "EUC-JP", "Ascii,jis,euc-jp,sjis,utf-8"); " Ascii,jis,euc-jp,sjis,utf-8 "in the order of different effects also have
Difference
3. In general, with Iconv, only when encountering the inability to determine the encoding of the original encoding, or iconv conversion can not be normal display when the mb_convert_encoding function
.
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 would be used.
$str = mb_convert_encoding ($str, "Ucs-2le", "JIS, Eucjp-win, Sjis-win");
$str = mb_convert_encoding ($str, "EUC-JP", "Auto");
Example:
$content = Iconv ("GBK", "UTF-8", $content);
$content = mb_convert_encoding ($content, "UTF-8", "GBK");
