$pagnow当前页$pagecount总页数if($pagenow>1){ $prepage=$pagenow-1;
echo "<a href='f.php?pagenow=$prepage'>上一页</a>";}if($pagenow<$pagecount){ $nexpage=$pagenow+1;
echo "<a href='f.php?pagenow=$nexpage'>下一页</a>";}显示当前页和共有多少页echo "当前页{$pagenow}/共{$pagecount}页";打印出页码的超链接方法一：for($i=1;$i<=$pagecount;$i++){ echo "<a href='f.php?pagenow=$i'>$i</a> ";
}方法二：for($j=1;$j<=$pagecount;$j++){if($currpage == $j){echo $j.' ';continue;} echo "<a href='?p=$j'>$j</a> ";}<a href="?p=1">首页</a><a href="?p=<?=$currpage+1?>">下页</a><a href="?p=<?php echo $currpage-1;?>">上页</a><a href="?p=<?=$pagecount?>">末页</a>
