php相簿功能實現(包含php圖片上傳,後台管理,瀏覽和刪除)教程例子，

相簿功能實現(包含php圖片上傳,後台管理,瀏覽和刪除)教程例子包括五個部分：

一、相簿首頁

        相簿首頁        
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 "目前記錄條數為：0";        }else{            $temp = explode("||",$myfile[0]);            echo "共有".$temp[0]."條內容";            echo "    ";            $p_count = ceil($temp[0]/8);            echo "分".$_count."頁顯示";            echo "    ";            echo "當前顯示第".$page."頁";            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 "第一頁 | ";        }else{            echo "$PATH_INFO?page=1'>第一頁 | ";        }        if($prev_page < 1){            echo "上一頁 | ";        }else{            echo "$PATH_INFO?page=$prev_page'>上一頁 | ";        }        if($next_page > $p_count){            echo "下一頁 | ";        }else{            echo "$PATH_INFO?page=$next_page'>下一頁 | ";        }        if($page >= $p_count){            echo "最後一頁
\n";        }else{            echo "$PATH_INFO?page=$p_count'>最後一頁
\n";        }    ?>    Upload Files

二、後台管理

        幕後處理頁面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 "指定檔案已經上傳成功！";            echo "
";            echo "點返回";        }else{            echo "檔案上傳失敗！";        }    }?>

三、圖片上傳

        相簿上傳頁面        
Image album upload page
    
        返回首頁        
    

四、圖片瀏覽

        查看圖片    
View images.
    php    error_reporting(0);    if(!$_GET["id"]){        echo "No assign id.";        echo "首頁";        exit();    }else{        ?>        返回首頁            $_GET['id'] ?>">刪除圖片
    php        $id = $_GET["id"];        $filename = "data.dat";        $myfile = file($filename);        $z = $myfile[0];        if($z == ""){            echo "目前記錄條數為0";        }else{            $temp = explode("||", $myfile[$z-$id]);            echo "
"."檔案名稱:".$temp[1]."
";            echo "
$temp[1].">
";            echo "
圖片簡介:".$temp[2]."
";            echo "
上傳日期:".$temp[3]."
";        }    }    ?>

五、刪除圖片

        刪除圖片php    error_reporting(0);    if(!$_GET["id"]){        echo "No id assign.";        echo "
";        echo "首頁";        exit();    }else{        $id = $_GET["id"];        $filename = "data.dat";        $myfile = file($filename);        $z = $myfile[0];        if($z == NULL){            echo "目前記錄條數為：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 "指定檔案已經刪除成功！";            echo "首頁";        }    }?>
