PHP - Quicker/more Simpler Way Of Doing This?

Hi,

I'm want to be able to change small site contents by using links like: site.com/?radio1, site.com/?radio2, but i want an easier way of making small bits of text change, for example, at the moment, i'm using:

Autofresh is: <?php
$link ='hits.php?on';
if (isset($_GET['on']))
echo "Enabled |<a href=\"?off\"> Disable?</a>"
?>
<?php
$link ='hits.php?on';
if (isset($_GET['off']))
echo "Disabled |<a href=\"?on\"> Enable?</a>"
?>

Is it possible to do that with only one

<?php
$link ='hits.php?on';
if (isset($_GET['off']))
echo "Disabled |<a href=\"?on\"> Enable?</a>"
?>

So i can have multiple echo's and assign which echo i want to use, for example:

<?php
$link ='hits.php?on';
if (isset($_GET['off']))
echo1 "Disabled |<a href=\"?on\"> Enable?</a>"
echo2 "Enabled |<a href=\"?off\"> Disable?</a>"
?>
<?php include echo2 ?>

i know that wont work, but since im new to php, i need to explain what i mean.

THANKS

I have this query that fully works the way it is, but I am wondering if I am overdoing some things in it.  I know this may be hard to tell without knowing the full relationship between all the tables in the query.  I'm basically running 3 subqueries mostly based on a timestamp value and other specific clauses per subquery.  Where the main query is only gathering based on the timestamp.   Like I said it works perfect from what I can verify by cross referencing the tables manually and checking the results the query returned.  I just want to know if there is a better way to do all this.

SELECT `products`.`id` AS `pid`, `products`.`prod_name`,
 
(SELECT COUNT(*) FROM `products` 
INNER JOIN `quote_deposits` ON `quote_deposits`.`product_id` = `products`.`id`
INNER JOIN `quote_responses` ON `quote_responses`.`id` = `quote_deposits`.`q_id`
WHERE `quote_responses`.`purchased` = 0 AND `quote_deposits`.`dep_date` >= $committed_start
) AS `committed`, 

(SELECT COUNT(`products`.`id`) FROM `products` 
  INNER JOIN `quote_deposits` ON `quote_deposits`.`product_id` = `products`.`id`
  INNER JOIN `quote_responses` ON `quote_responses`.`id` = `quote_deposits`.`q_id`
  WHERE `quote_responses`.`purchased` = 1 AND `products`.`id` = `pid` AND `quote_deposits`.`dep_date` >= $committed_start
) AS `total_per_item`,

  INNER JOIN `schedule` ON `schedule`.`deposit_id` = `quote_deposits`.`id`
