将变量拆分为定义的块数

Question

I am trying to make my own password hash, which I thought I could use chunk_split() to split the string into two pieces. Apparantly I didn't understand the documentation!

Now, my question, is there a different way to split the string - PHP would be nice, other language is not a problem 'tough - into pieces of 3?

I do have other ideas, but this looks like the best way to me.

Don't try to roll out your own encryption scheme or hashing algorithm. If you're not an expert, there's many mistakes that you'll make. Why reinvent the wheel when are already many good solutions available on the Internet? If you're using PHP 5.x, then you can use the built-in solutions: password_hash() and password_verify()

See: Cryptography — Why shouldn't we roll our own?

However, if it's just for learning purposes, then you can use str_split() with the second parameter.

Example:

$str = 'foobarbaz';
print_r(str_split($str, 3));

Output:

Array
(
    [0] => foo
    [1] => bar
    [2] => baz
)
