PHP Absolutely unique, random string

Is there any php function in our time, which generates absolutely unique, random string? Or rephrase the question, how to make absolutely unique and random string in php in our time? Is it enough to combine couple of randomizing functions?

Some other people have also found ways to do this, it seems.
