php hash表单字符串为整数 [英] php hash form string to integer

问题描述

PHP是否有内置函数来执行字符串到整数哈希，这是难以逆转的东西？

Does PHP have a built in function for doing string to integer hashes, something that's difficult to reverse?

现在，我知道我可以放弃做一个md5，并将其子字符串视为基数为16的数字，但我正在寻找内置的东西。

Now, I know I can probably get away with doing an md5, and treating a substring of it as a radix 16 number, but I'm looking for something built in.

谢谢。

推荐答案

我认为最好的选择是选择标准哈希[ md5（）或 sha1（）]获取字符串的哈希值，然后获得整数哈希，得到 base_convert（$ hash，16,10）那应该将你的哈希值转换为整数哈希。

I think the best bet would chose a standard hash [either md5() or sha1()] to obtain a hash of your string, and then to get an integer hash, to a base_convert($hash, 16, 10) and that should convert your hash into a integer hash.

希望我能正确理解你的问题。

Hope I am understanding your issue correctly.
