$_POST syntax question

[den160593]

Hi,

I'm just slightly confused on the $_POST syntax and I can't find any explanations on the internet (probably cos I'm not searching for the right thing, but hopefully you guys can help 😃)

$title = $_POST['Submit'] . " " .
$_POST['type'] . " : " .
$_POST['Name'];

Well the thing I'm confused by is the dots (.)

I have no-idea what they mean and what they do, I understand that the " " enclose text and that the " : " is the equivalent of "space colon space" and stuff and I know that the $_POST['type'] refers to the variable under the name of type from the previous page, but no clue at all about the dots.

So what do they do and how are they used? If you know of a link to a tutorial about this it would be very handy

Thanks in advance

The dot is PHP's string concatenation operator, i.e. it appends the string to the right of it onto the string to the left of it.
