This function creates relatively secure random passwords. It's by no means ideal, but it should work in most non-critical situations. The nice thing is the generator attempts to create passwords that people can pronounce and chooses letters that won't be mistaken for others (such as the numeral "1", an upper-case "i" and a lower-case "L"). To keep the code short much of this functionality is very rudimentary, but it's better than nothing.

This is a quick and easy method to generate a somewhat random password. This simply generates the MD5 hash for the integer returned by the time() function and then truncates it to the specific length.

Creates a random string, usefull for passwords etc.

Use: $password = makeRandomPassword($Length);

If $Length is not specified (ie $password = makeRandomPassword();) then it will default to 8 characters

It works with Array types. The example is a simple list of numbers, but the array could contain anything; lists of strings, functions, DOM nodes, whatever. Unfortunately, a lot of things that seem like arrays in the DOM aren't really, so you can't shuffle the images on a page with just document.images.shuffle() all by itself.
