Converting ColdFusion CFIF to PHP IF statement

Dude...I feel like such an idiot when I look over something that obvious!

Thanks for your extra set of eyes. I have one more question.

In another area I want nothing to display if the column "GH" is equal to the word "none" but I can't seem to get that one to work. It just keeps displaying the word "none" It worked in CFM but the if statement was written from a different angle...
<cfif WA_eCart_DisplayInfo(CardCart, "GreetingHead") NEQ "none">#WA_eCart_DisplayInfo(CardCart, "GreetingHead")#</cfif>

So far I have for this I have...
<?php
if ($GCcart->TotalColumn("GH") == "none") {
?>



<?php
} else {
?>

<?php echo $GCcart->DisplayInfo("GH"); ?>

<?php
}
?>



Is there a command I need to put in to PHP that represents nothing or empty?

Thanks,

Grant
