It joins each element which it prints by space. Your code doesn't work because you should put php opening and closing tags <?PHP and ?> and whole your code should be inside the tags.

In PHP, the period (.) serves the same purpose as the plus (+) in other languages: string concatenation. Here, PHP will treat the integer ($i) as a string before appending the space, for output.
