范例
Example #1 hash_algos() 例程
在 PHP 7.4.0 中,hash_algos() 会返回下表所示的算法清单:
<?phpprint_r(hash_algos());?>
以上例程的输出类似于:
Array ( [0] => md2 [1] => md4 [2] => md5 [3] => sha1 [4] => sha224 [5] => sha256 [6] => sha384 [7] => sha512/224 [8] => sha512/256 [9] => sha512 [10] => sha3-224 [11] => sha3-256 [12] => sha3-384 [13] => sha3-512 [14] => ripemd128 [15] => ripemd160 [16] => ripemd256 [17] => ripemd320 [18] => whirlpool [19] => tiger128,3 [20] => tiger160,3 [21] => tiger192,3 [22] => tiger128,4 [23] => tiger160,4 [24] => tiger192,4 [25] => snefru [26] => snefru256 [27] => gost [28] => gost-crypto [29] => adler32 [30] => crc32 [31] => crc32b [32] => crc32c [33] => fnv132 [34] => fnv1a32 [35] => fnv164 [36] => fnv1a64 [37] => joaat [38] => haval128,3 [39] => haval160,3 [40] => haval192,3 [41] => haval224,3 [42] => haval256,3 [43] => haval128,4 [44] => haval160,4 [45] => haval192,4 [46] => haval224,4 [47] => haval256,4 [48] => haval128,5 [49] => haval160,5 [50] => haval192,5 [51] => haval224,5 [52] => haval256,5 )
