示例 #1 mb_encoding_aliases() example
<?php
$encoding = 'ASCII';
$known_encodings = mb_list_encodings();
if (in_array($encoding, $known_encodings)) {
$aliases = mb_encoding_aliases($encoding);
print_r($aliases);
} else {
echo "Unknown ($encoding) encoding.\n";
}
?>
以上例程的输出类似于：

[2] => ANSI_X3.4-1986
[3] => ISO_646.irv:1991
