String Concatenation in PHP

Why in Learn PHP string Concatenation is code like this?
echo “one” . " " . “two” . " " . “three”; // Prints: one two three
When I need only (dot) . for string Concatenation. It is confusing. You are making people silly then.
Should not be. echo “one” . “two” . “three”;

Hi,
why don’t you try it? You can do it that way.
But it would print “onetwothree”

Thank you very much. It is just about trie and trie. If I do not trie then will not get anything. Then I will be still struggling. I was confused by all the dots and quotations marks. Thank you once more and happy coding.
