For some reason this function (but not mcrypt_list_algorithms()) returns each element in the array twice. If you have this problem, try array_unique(mcrypt_list_algorithms()).
(PHP 4 >= 4.0.2, PHP 5, PHP 7)
mcrypt_enc_get_algorithms_name — 返回打开的算法名称
This function has been DEPRECATED as of PHP 7.1.0. Relying on this function is highly discouraged.
$td
)本函数返回算法名称。
td加密描述符。
以字符串格式返回打开的加密算法名称。
Example #1 mcrypt_enc_get_algorithms_name() 例程
<?php
$td = mcrypt_module_open(MCRYPT_CAST_256, '', MCRYPT_MODE_CFB, '');
echo mcrypt_enc_get_algorithms_name($td). "\n";
$td = mcrypt_module_open('cast-256', '', MCRYPT_MODE_CFB, '');
echo mcrypt_enc_get_algorithms_name($td). "\n";
?>
以上例程会输出：
CAST-256 CAST-256
