Insert space in a PHP variable

Navigation
-7

Hello, I see that it's a very simple question, apparently, but I'm finding it very difficult to do this, I probably should be looking wrong on the subject, what I'm trying to do is this: 

$var3 = $var1." ".$var2;

In case var3 would get the string var1 + var2 with a space between them, but in that way I can not get what I want, any way I can do that in this style? (in a simple way).

EDIT: I tested the code and now it worked, there probably should have been some runtime error.

You can use the sprintf function, see: 

$var1 = "Olá";
$var2 = "Mundo";
$var3 = sprintf("%s %s", $var1, $var2);
echo $var3; // Olá Mundo

You can use as many parameters as you want in the sprintf function that PHP will put in the sequence that you define: 

$texto = sprintf("%s %s %s %s", $var1, $var2, "Outra mensagem", "final");
echo $texto; // Olá Mundo Outra mensagem final
