ialsoagree Posted February 22, 2010 Share Posted February 22, 2010 If uniqueness is not necessary, you can use a function like md5 or sha1 to hash a random value like the current milliseconds or a number generated with rand.

ialsoagree Posted February 22, 2010 Share Posted February 22, 2010 There's a few approaches to this. Primarily your goal is to take a unique value and turn it into a unique gibberish string. It depends on the needs of your project, but one approach would be use an incrementing value (increments after a unique code is generated) and then encrypt the value using a reversible encryption such as mcrypt_generic(). The incremented value will never be the same (it will always be greater than any previous value) and thus the encryption will never be the same. The encryption will make it much more difficult to determine what value is being used (and thus, to predict the next value that will be used and it's resulting key).
