php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

一、相册首页

    
    
    


    
The simple photo album.
    
    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 "
";
            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 "$temp[0].">$temp[1];
                        if($flag[0]>180||$flag[1]>100){
                            echo " width=180 height=".ceil($flag[1]*180/$flag[0]);
                        }
                        echo " border=\"0\">";
                    }else{
                        echo "";

                    }
                }

            }
            echo "";
        }
        echo "
";
        $prev_page = $page - 1;
        $next_page = $page + 1;
        if($page <= 1){
            echo "第一页 | ";
        }else{
            echo "$PATH_INFO?page=1'>第一页 | ";
        }
        if($prev_page < 1){
            echo "上一页 | ";
        }else{
            echo "$PATH_INFO?page=$prev_page'>上一页 | ";
        }
        if($next_page > $p_count){
            echo "下一页 | ";
        }else{
            echo "$PATH_INFO?page=$next_page'>下一页 | ";
        }
        if($page >= $p_count){
            echo "最后一页
\n";
        }else{
            echo "$PATH_INFO?page=$p_count'>最后一页
\n";
        }
    ?>

    Upload Files

二、后台管理

    
    


php
    error_reporting(1);
    if($_FILES['upfile']['name'] == NULL){
        echo "No file choice.";
        echo "返回";
    }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 "
";
            echo "指定文件已经上传成功！";
            echo "
";
            echo "点返回";
        }else{
            echo "文件上传失败！";
        }
    }
?>

三、图片上传

    
    


    

    
Image album upload page
    

        返回首页
        

    

四、图片浏览

    
    



    
View images.
    php
    error_reporting(0);
    if(!$_GET["id"]){
        echo "No assign id.";
        echo "首页";
        exit();
    }else{
        ?>
        返回首页    
        $_GET['id'] ?>">删除图片

    php
        $id = $_GET["id"];
        $filename = "data.dat";
        $myfile = file($filename);
        $z = $myfile[0];
        if($z == ""){
            echo "目前记录条数为0";
        }else{
            $temp = explode("||", $myfile[$z-$id]);
            echo "
"."文件名:".$temp[1]."
";
            echo "
$temp[1].">
";
            echo "
图片简介:".$temp[2]."
";
            echo "
上传日期:".$temp[3]."
";
        }
    }
    ?>

五、删除图片

    
    


php
    error_reporting(0);
    if(!$_GET["id"]){
        echo "No id assign.";
        echo "
";
        echo "首页";
        exit();
    }else{
        $id = $_GET["id"];
        $filename = "data.dat";
        $myfile = file($filename);
        $z = $myfile[0];
        if($z == NULL){
            echo "目前记录条数为：0";
        }else{
            $temp = explode("||", $myfile[$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];
            }
            $fp = fopen($filename, "w");
            fwrite($fp, $text2);
            fwrite($fp, $text1);
            fclose($fp);
            echo "指定文件已经删除成功！";
            echo "首页";
        }

    }
?>
