Note that the concatenation operator (.=) needs a specified variable on both sides. If you are
running a loop to read out a list of items from $table (this, is, my, list)
<?php
$surface .= $table;
?>
will give you ".this is my list". To get rid of the initial dot, you need to specify an
empty $surface first:
<?php
$surface='';
$surface .= $table;
?>
giving "this is my list".
