Add Class to body tag when PHP finds a word within a web page

Question

I am trying to add a class to the body tag when php finds a certain word within a bit of html code.

So far I have come up with:

<?php echo $this->row->description;
if (stripos($this->row->description, 'Sold')!== false) {
    echo 'true';  
} 
?>

I can see the 'true' being echoed on the web page. So I know it's working and it doesn't show if the word 'sold' is not on the web page.

What I want to do is change echo 'true'; to something that adds the class 'true' to the body tag of the web page.

You can do something like $append_to_body = 'true';, then in your body tag add class="<?php echo $append_to_body?>" — scrowler, Commented Oct 21, 2013 at 2:05

This should be enough:

<body class="<?php echo stripos($this->row->description, 'Sold')!==false?'true':'' ?>">

This didn't work for me (I tried to use it as an ID not a class), it just left "" in the body tag. You can see it here: estate.marketingagencyleeds.co.uk/search-for-a-property/1-student-property-close-to-university

@simon it's blank '' because the if evaluates to FALSE

@Simon: In this case it will be empty is Sold is not found. You get the description before to print the body tag right?
