You have a couple of options... just pick the one that suits you...

<?
echo "\"{$_POST[$var]},\"";
echo '"'.$_POST[$var].',"';
?>
[/snip]

var should not have a $ in front of it, should it?

echo "\"{$_POST['var']},\"";
echo '"'.$_POST['var'].',"';

That all depends. Consider the following:

Assume:
<input type='text' name='something' value='foo'>
to be posted to the script

print '"$_POST[$var],"'; // prints (literally): "$_POST[$var],"
print '"'.$_POST['something'].","; // prints: "foo,"
print '"'.$_POST[$var].","; // Issues a 'notice: undefined index..' and
prints: ","

$var = 'something';
print '"'.$_POST[$var].","; // prints: "foo,"

Pick your flavor.
