ถามเรื่องการแสดงผลแต่ละหน้าตามตัวอักษร เหมือนใน hi5 อะคับ

$Search = $_GET["Search"];
	if($Search=="ALL" || $Search==""){
		$searchkey = "";
	}else{
		$searchkey = " name LIKE '$Search%' ";
	}

$show  = "SELECT id ,name ";
$show .= " FROM  country ";
$show .=" WHERE ".$searchkey;

if(isset($_GET["text"])){
	echo $sql = "select * from table where fieldname like '" . $_GET["text"] . "%';";
}
$char = "abcdefghijklmnopqrstuvwxyz";
$navi = str_split($char);
echo "<ol>";
foreach($navi as $text){
	echo "<li onclick=\"location.href='?text=" . strtoupper($text) . "'\">" . strtoupper($text) . "</li>";
}
echo "</ol>";
