Using Variables

[ShaKeD]

Hey, I was starting using php again and I don't remember how can I use this option of Variables:

$x = "abc";
$x. = "def";
echo $x;

[u][b]display: [/b][/u]

abcdef


but I don't get the display, I get an error;
[b]Parse error: parse error, unexpected '=' in C:\apache2\htdocs\down.php on line 3[/b]

Your space is in the wrong place:

$x .= "def";

The . and = should be "touching"
