Is it correct to put variable between commas when echoing?

so, in this video (and some of the previous ones) I see statements like this:

echo "hello, $name";

is this correct? shouldn't it be more like this:

echo "hello, " . $name;

Yes, it is correct. The double quotes tells php to expand the variable (put the value of the variable) inside the string. If we want that to not happen, we'd use single quotes around the string. Hope this helps! :sparkles:

Thanks, Jennifer. I didn't know that difference between the two types of quotes.
