First make your search term safe and then use it in query using LIKE instead of =.

$safe = mysqli_real_escape_string($link, $_GET['iid']); 
$safe = trim($safe);

Then query could be,

$sql = "SELECT * FROM qcdataa2 Where first_name LIKE '$safe%' ";

Try sending data with urlencode() and decode it with urldecode()
