(PHP 7 >= 7.2.0, PHP 8)
hash_hmac_algos — 返回适用于 hash_hmac 的已注册散列算法列表
说明
hash_hmac_algos(): array参数
此函数没有参数。
返回值
返回数字索引数组，包含适用于 hash_hmac() 支持的散列算法列表。
示例
示例 #1 hash_hmac_algos() 示例
<?php
print_r(hash_hmac_algos());以上示例的输出类似于：
Array

)注释
注意:在 PHP 7.2.0 之前，获取支持的散列算法列表的唯一方法是调用 hash_algos()，该方法也会返回不适合 hash_hmac() 的散列算法。
