看看
iconv()或
mb_convert_encoding()。只是顺便：为什么不
utf8_enpre()和
utf8_depre()为你工作？
utf8_depre —将使用UTF-8编码的ISO-8859-1字符的字符串转换为单字节ISO-8859-1
utf8_enpre —将ISO-8859-1字符串编码为UTF-8
所以本质上
$utf8 = 'ÄÖÜ'; // file must be UTF-8 enpred$iso88591_1 = utf8_depre($utf8);$iso88591_2 = iconv('UTF-8', 'ISO-8859-1', $utf8);$iso88591_2 = mb_convert_encoding($utf8, 'ISO-8859-1', 'UTF-8');$iso88591 = 'ÄÖÜ'; // file must be ISO-8859-1 enpred$utf8_1 = utf8_enpre($iso88591);$utf8_2 = iconv('ISO-8859-1', 'UTF-8', $iso88591);$utf8_2 = mb_convert_encoding($iso88591, 'UTF-8', 'ISO-8859-1');所有这些都应该做同样的事情-
utf8_en/depre()不需要特殊的扩展，
mb_convert_encoding()不需要ext /
mbstring，也
iconv()需要ext / iconv。
