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:
Array ( [0] => ANSI_X3.4-1968 [1] => iso-ir-6 [2] => ANSI_X3.4-1986 [3] => ISO_646.irv:1991 [4] => US-ASCII [5] => ISO646-US [6] => us [7] => IBM367 [8] => cp367 [9] => csASCII )
