注意:并非所有接受编码名称字符串都位于此处。
mb_convert_encoding() 接受 "gbk",但它不在此处。
(PHP 5, PHP 7, PHP 8)
mb_list_encodings — 返回所有支持的编码的数组
此函数没有参数。
返回一个数字索引的数组。
此函数不会发出任何错误。
示例 #1 mb_list_encodings() 示例
<?php
print_r(mb_list_encodings());
?>
上面的示例将输出类似于以下内容
Array ( [0] => pass [1] => auto [2] => wchar [3] => byte2be [4] => byte2le [5] => byte4be [6] => byte4le [7] => BASE64 [8] => UUENCODE [9] => HTML-ENTITIES [10] => Quoted-Printable [11] => 7bit [12] => 8bit [13] => UCS-4 [14] => UCS-4BE [15] => UCS-4LE [16] => UCS-2 [17] => UCS-2BE [18] => UCS-2LE [19] => UTF-32 [20] => UTF-32BE [21] => UTF-32LE [22] => UTF-16 [23] => UTF-16BE [24] => UTF-16LE [25] => UTF-8 [26] => UTF-7 [27] => UTF7-IMAP [28] => ASCII [29] => EUC-JP [30] => SJIS [31] => eucJP-win [32] => SJIS-win [33] => JIS [34] => ISO-2022-JP [35] => Windows-1252 [36] => ISO-8859-1 [37] => ISO-8859-2 [38] => ISO-8859-3 [39] => ISO-8859-4 [40] => ISO-8859-5 [41] => ISO-8859-6 [42] => ISO-8859-7 [43] => ISO-8859-8 [44] => ISO-8859-9 [45] => ISO-8859-10 [46] => ISO-8859-13 [47] => ISO-8859-14 [48] => ISO-8859-15 [49] => EUC-CN [50] => CP936 [51] => HZ [52] => EUC-TW [53] => BIG-5 [54] => EUC-KR [55] => UHC [56] => ISO-2022-KR [57] => Windows-1251 [58] => CP866 [59] => KOI8-R )
此函数列出了编码的常用名称,
如果您正在寻找的名称不在列表中,但可以工作,则它可能是返回的编码名称之一的别名
mb_encoding_aliases 返回编码的别名,
不幸的是,没有反向执行此操作的方法(例如,没有函数会为 'GBK' 返回 'CP936')
您可以通过执行以下操作列出所有编码名称及其已知别名:
<?php
print_r(
array_unique(
array_merge(
$enc = mb_list_encodings(),
call_user_func_array(
'array_merge',
array_map(
"mb_encoding_aliases",
$enc
)
)
)
)
);
?>
print "<pre>";
print_r(mb_list_encodings());
并在 win8.1 中的 xampp 上获得了以下结果。
