php获取文件夹路径内的图片以及分页显示示例

<div style="width: 90%; margin: 10px auto; border: 1px solid #ccc; text-align: center">
<?php
$page=isset($_GET['page'])?$_GET['page']:0;//从零开始
$imgnums = 10; //每页显示的图片数
$path="upload"; //图片保存的目录
$handle = opendir($path);
$i=0;
while (false !== ($file = readdir($handle))) {
list($filesname,$ext)=explode(".",$file);
if($ext=="gif" or $ext=="jpg" or $ext=="JPG" or $ext=="GIF" ) {
if (!is_dir('./'.$file)) {
$array[]=$file;//保存图片名称
++$i;
}
}
}

if($array){
rsort($array);//修改日期倒序排序
}
for($j=$imgnums*$page; $j<($imgnums*$page+$imgnums)&&$j<$i; ++$j){
echo '<div>';
echo $array[$j],'<br />';
echo "<img src=".$path."/".$array[$j]."><br />";
echo '</div>';
}
$realpage = @ceil($i / $imgnums) – 1;
$Prepage = $page-1;
$Nextpage = $page+1;
if($Prepage<0){
echo "上一页 ";
echo "<a href=?page=$Nextpage>下一页</a> ";
echo "<a href=?page=$realpage>最末页</a> ";
}elseif($Nextpage >= $realpage){
echo "<a href=?page=0>首页</a> ";
echo " <a href=?page=$Prepage>上一页</a> ";
echo " 下一页";
}else{
echo "<a href=?page=0>首页</a> ";
echo "<a href=?page=$Prepage>上一页</a> ";
echo "<a href=?page=$Nextpage>下一页</a> ";
echo "<a href=?page=$realpage>最末页</a> ";
}
?>
</div>
