php相册功能怎么实现?
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:

html>
head>
meta charset="utf-8">
title>
相册首页/title>
style>
body{
width:800px;
margin:0 auto;
test-align: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;
$iceil($current_size/4);
$i++){
for($j=0;
$j4;
$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='$PATH_INFO?page=1'>
第一页/a>
| ";
}
if($prev_page 1){
echo "上一页 | ";
}
else{
echo "a href='$PATH_INFO?page=$prev_page'>
上一页/a>
| ";
}
if($next_page >
$p_count){
echo "下一页 | ";
}
else{
echo "a href='$PATH_INFO?page=$next_page'>
下一页/a>
| ";
}
if($page >
= $p_count){
echo "最后一页/p>
\n";
}
else{

if($_FILES['upfile']['name'] == NULL){
echo "No file choice.";
echo "a href='upfile.php'>
返回/a>
";
}
else{
$filepath = "/Library/WebServer/Documents/test/images/";
$tmp_name = $_FILES['upfile']['tmp_name'];
$filename = $filepath.$_FILES['upfile']['name'];
// echo $filename;
if(move_uploaded_file($tmp_name,$filename)){
$dataname = "data.dat";
$myfile = file($dataname);
if($myfile[0] == ""){
$fp = fopen($dataname, "a+");
fwrite($fp,"1||".$_FILES['upfile']['name']."||".$_POST["content"]."||".date(Y年m月d日)."\n");
fclose($fp);
}
else{
$temp = explode("||", $myfile[0]);
$temp[0]++;
$fp = fopen($dataname, "r");
$line_has = fread($fp,filesize("$dataname"));
fclose($fp);
$fp = fopen($dataname, "w");
fwrite($fp,$temp[0]."||".$_FILES['upfile']['name']."||".$_POST["content"]."||".date("Y年m月d日")."\n");
fwrite($fp,"$line_has");
fclose($fp);
}
echo "p>
/p>

else{
$temp = explode("||", $myfile[$z-$id]);
print_r($temp);
$filepath = "/Library/WebServer/Documents/test/images/";
$imgfile = $filepath.$temp[1];
echo $imgfile;
unlink($imgfile);
for($i=0;
$i($z-$id);
$i++){
$temp2 = explode("||", $myfile[$i]);
$temp2[0]--;
if($temp2[0]>
0)
$text2 = $text2.$temp2[0]."||".$temp2[1]."||".$temp2[2]."||".$temp2[3];
}
for($i=($z-$id+1);
$i$z;
$i++){
$text1 = $text1.$myfile[$i];
