I'm just starting in php (and on stackoverfow) and I was using some code founded on php.net's manual to do some tests. I tried to edit a line to add a \n.

```
echo gettype($a_bool)."\n";
echo gettype($a_str);

```

Those 2 lines are supposed to display

```
boolean
string

```

on my page but instead I get:

```
boolean string

```

I'd like to know if the problem is coming from my use of \n or concatenate or from somewhere else.
Edit : I'm adding my code that I'm executing on mozilla with a local server using apache.

```
<?php
$a_bool = TRUE;   // un booléen
$a_str  = "foo";  // une chaîne de caractères
$a_str2 = 'foo';  // une chaîne de caractères
$an_int = 12;     // un entier

echo gettype($a_bool)."\br";
echo gettype($a_str);

// Si c'est un entier, incrément de 4
if (is_int($an_int)) {
    $an_int += 4;
    }

// Si $a_bool est une chaîne de caractères, on l'affiche
if (is_string($a_bool)) {
    echo "String: $a_bool";
}
?>

```

I changed my "\n" for a "\br" as recomended and this is what's displayed on my page now :

```
boolean\brstring

```

Just fixed it with   
 (I was just not using it correctly).
Thank you.
