[Trying to add a click counting code.]

<?php 
if(!file_exists('counter.txt')){ 
file_put_co 

ntents('counter.txt', '0'); 
} 
if($_GET['click'] == 'yes'){ 
file_put_contents('counter.txt', ((int) file_get_contents('counter.txt')) + 1); 
header('Location: ' . $_SERVER['SCRIPT_NAME']); 
die; 
} 
?>

I am trying to add a click counter to my search button. I found the code online.

I need to add <a href="?click=yes"></a> to

<form id="tfnewsearch" method="get" action="http://www.google.com/search?q=<?php echo $_REQUEST['q']?>">
<input type="text" id="tfq" class="tftextinput4" name="q" size="21" maxlength="120" <?php if(isset($_REQUEST['q'])) echo " value='{$_REQUEST['q']}'"?> autocomplete="off"  placeholder="Search Google..."><input type="submit" value="" class="tfbutton4">
</form>

Would anyone know how. Thanks
