函數(shù)名稱：mb_encoding_aliases()

函數(shù)描述：mb_encoding_aliases() 函數(shù)返回一個(gè)數(shù)組，其中包含指定字符編碼的所有別名。

參數(shù)：無

返回值：一個(gè)包含所有別名的數(shù)組，如果沒有別名，則返回空數(shù)組。

示例：

// 獲取 UTF-8 編碼的所有別名
$aliases = mb_encoding_aliases('UTF-8');
print_r($aliases);

輸出結(jié)果：

Array
(
    [0] => UTF-8
    [1] => utf8
    [2] => ucs-2
    [3] => ucs-2be
    [4] => ucs-2le
    [5] => ucs-4
    [6] => ucs-4be
    [7] => ucs-4le
    [8] => utf-16
    [9] => utf-16be
    [10] => utf-16le
    [11] => utf-32
    [12] => utf-32be
    [13] => utf-32le
    [14] => UNICODE-1-1
    [15] => UNICODEBIG
    [16] => UTF-16
    [17] => UTF-16BE
    [18] => UTF-16LE
    [19] => UTF-32
    [20] => UTF-32BE
    [21] => UTF-32LE
    [22] => UTF8
    [23] => UNICODE
    [24] => UNICODEBIGENDIAN
