php怎么实现相册功能?

相册功能实现(包含php图片上传,后台管理,浏览和删除)教程例子包括五个部分:

一、相册首页

<html>
<head>
    <meta charset="utf-8">
    <title>相册首页</title>
    <style>
        body{
            width:800px;
            margin:0 auto;
            test-align:center;
        }
    </style>
</head>
<body>
    <h1>The simple photo album.</h1>
    <center>
    <?php
    error_reporting(0);
    if(!$_GET["page"]){
        $page = 1;
    }else
        $page = $_GET["page"];
        $filename = "data.dat";
        $myfile = file($filename);
        $z = $myfile[0];
        if($z == NULL){
            echo "目前记录条数为:0";
        }else{
            $temp = explode("||",$myfile[0]);
            echo "共有".$temp[0]."条内容";
            echo "    ";
            $p_count = ceil($temp[0]/8);
            echo "分".$_count."页显示";
            echo "    ";
            echo "当前显示第".$page."页";
            echo "    ";
            echo "<br>";
            if($page != ceil($temp[0]/8)){
                $current_size = 8;
            }else{
                $current_size = $temp[0]%8;
            }
            if($current_size == 0){
                $current_size = 8;
            }
            for($i=0;$i<ceil($current_size/4);$i++){
                for($j=0;$j<4;$j++){
                    $temp = explode("||", $myfile[$i*4+$j+($page-1)*8]);
                    if(($i*4+$j+($page-1)*8)<$z){
                        $imgfile = "./images/".$temp[1];
                        $flag = getimagesize($imgfile);
                        echo "<a href=viewimage.php?id=".$temp[0]."><img src=/test/images/".$temp[1];
                        if($flag[0]>180||$flag[1]>100){
                            echo " width=180 height=".ceil($flag[1]*180/$flag[0]);
                        }
                        echo " border=\"0\"></a>";
                    }else{
                        echo "";
                    }
                }
            }
            echo "</table>";
        }
        echo "<p>";
        $prev_page = $page - 1;
        $next_page = $page + 1;
        if($page <= 1){
            echo "第一页 | ";
        }else{
            echo "<a href=&#39;$PATH_INFO?page=1&#39;>第一页</a> | ";
        }
        if($prev_page < 1){
