Greetings to all,
I am an old guy who have started to learn html, css and php.
Is there any difference using comma vs punctuation when concatenate?
$number = 5;
$text = “hello”;
echo “Coool string”, " and another string" . " " . $number, 5 * 44;
Both seems to work but all books I have started to read all use punctuation…but why not use comma?
