<?php
	if($page>1){
	echo "<a href=?page=".($page-1)."&keyword=$keyword>Prev</a>&nbsp;&nbsp;</br>";}
	for($i=1;$i<=$totalpage;$i++){ 
	     if($i==$page)
	    echo "[<b>$i</b>]&nbsp;&nbsp;";
	    else
	    echo "<a href=?page=$i&keyword=$keyword>$i</a>&nbsp;&nbsp;";
	    } 
	if($page<$totalpage){
	echo "<a href=?page=".($page+1)."&keyword=$keyword>next</a>&nbsp;&nbsp;</br>";
