adsense ad_format concat

[myseng]

i wanted to concat string into something look like this:-

google_ad_format = "728x90_as";

from two argument passes down from the main function and that argument is the width(728) and height(90) and store into a variable $adFormat as "728x90_as"

so that when i put this code into my adsense code like this it will work:-

google_ad_format = $adFormat;

i've tried this before
$x = 'x';
$quote = '"';
$as = '_as';
$adFormat = "$quote$adWidth$x$adHeight$as$quote";

AND THIS

$adFormat = '"'.$adWidth."x".$adHeight."_as".'"';

and then called

google_ad_format = $adFormat;
which it dont work. no ads displayed on my page...

please help

THe first one would work. You're just missing the periods in between each variable. It should look like:

$x = 'x';
$quote = '"';
$as = '_as';
$adFormat = $quote.$adWidth.$x.$adHeight.$as.$quote;

That should work. No reason for it not to.

Edit
Mocked up a code for you.

<?php

$adWidth = "728";
$adHeight = "90";
$x = "x";
$as = "_as";
$quote = '"';

$adFormat = $quote.$adWidth.$x.$adHeight.$as.$quote;

echo($adFormat);

?>
