It is same as
[PHP]$variablename = "some value";
$variablename = $variablename . 10;[/PHP]

in php dot(.) is basically the string concatenation operator. so writing
[PHP]$var .= 10; [/PHP]
[PHP]$var = $var . 10[/PHP];

here in this example 10 will be concatenated with the value of $var as string. There will be no mathematical addition if $var also contain number too.
