if(empty($U_name)){
    $msg .= "Name can not be empty <br>";
}
if(empty($U_user_name)){
    $msg .= "Username can not be empty <br>";
}
echo "<div class='error'>".$msg."</div>";

here .(dot) is the concatenation operator. could anyone please make me clear the code of the last statement.

Looks right to me. Are you getting any errors? You may want to set `$msg` before the if statement: `$msg = '';` – Jay Blanchard Oct 07 '16 at 15:48
No i don't get any error but the last statement "how concatenation works" not clear to me? – user1957167 Oct 07 '16 at 15:50

my question is how the html goes with php code. – user1957167 Oct 07 '16 at 15:58
What do you mean? – Jay Blanchard Oct 07 '16 at 16:04
how the associated div tag applies to the $msg variable – user1957167 Oct 07 '16 at 16:08
This is not a duplicate per-say of the question linked to but it is a duplicate of a commonly asked question. Your code is fine you need to initialize your variable $msg first is all. You can not concatenate anything to a variable that does not exist yet. This is where the General Reference Question (duplicate) comes in. – Blizzardengle Oct 07 '16 at 16:13
Do not do this, use a controller to bind the message or at least something like this: – Marcos Alexandre Sedrez Oct 07 '16 at 16:24
