Question: What is the best way of doing this ?

```
rand('Helloworld','Hi world');

```

I know this is not working as rand needs a min and max number, but what is the solution for this ?

Answer: 
Use [array\_rand](http://php.net/manual/en/function.array-rand.php).
```
function rand_of() {
    $_ = func_get_args();
    return $_[rand(0, count($_) - 1)];
}

echo rand_of("foo", "bar", "baz");

```
