php多檔案上傳代碼二_PHP教程

fileclass.php檔案代碼如下:

class more_file_upload{
const FILE_PATH='../filehandle/uploadfile/';
var $file_type;
var $file_type_array;
var $file_type_string;
var $file_name;
var $file_size;
var $file_tmp_name;
var $file_error;
var $handledate;
static $totalsize=0;

function __construct($file_name,$file_error,$file_size,$file_tmp_name,$file_type){
$this->handledate=date('m-d-Y');
if (!empty($file_name)){
$this->file_name=$file_name;
$this->file_error=$file_error;
$this->file_size=$file_size;
$this->file_tmp_name=$file_tmp_name;
$this->file_type=$file_type;
$this->file_type_array=array('text/plain','image/gif','image/jpg','text/html','image/pjpeg','image/png','application/msword','application/pdf');

$this->show_execute_message($this->file_error,$this->file_name,$this->file_type,$this->file_size);
}
}

function __destruct(){
$this->file_name = NULL;
$this->file_error = NULL;
$this->file_size = NULL;
$this->file_tmp_name = NULL;
$this->file_type = NULL;
self::$totalsize = 0;
}

function show_execute_message($smfileerror,$smfilename,$smfiletype,$smfilesize){
if($smfileerror>0){
switch ($smfileerror){
case 1: $smfilemessage='檔案超過伺服器的約定大小！';break;
case 2: $smfilemessage='檔案超過指定的檔案大小！';break;
case 3: $smfilemessage='檔案只上傳了部分！';break;
case 4: echo "$this->file_name ".'檔案上傳失敗！
';break;
}
self::__destruct();
}else{
$smfiletypeflag=array_search($smfiletype,$this->file_type_array);
if($smfiletypeflag == false){
$smfilemessage='檔案類型不對，請核實！';
self::__destruct();
}else{
$resflag=$this->move_file($this->file_tmp_name,$this->file_name);
if ($resflag == 1){
$smfilemessage='檔案上傳成功！';
self::$totalsize+=intval($smfilesize);
self::__destruct();
}else{
$smfilemessage='檔案上傳失敗！';
self::__destruct();
}
}
}
$smfilesize=$smfilesize/1024;
$smfilesizeformat=sprintf('%01d',$smfilesize);
echo '
'.$smfilename.'
'.$smfiletype.'
'.$smfilesizeformat.'
'.$smfilemessage.'
';
}

function move_file($mvfiletmp,$mvfilename){ //移動檔案
$mvfilenamearr=explode('.',basename($mvfilename));
$mvtime=mktime();
$mvfilenamearr[0]=$this->rand_string(10)."$mvtime";
$mvfilename=implode('.',$mvfilenamearr);

if (is_uploaded_file($mvfiletmp)){
$uploadfile=self::FILE_PATH."$mvfilename";
$result=move_uploaded_file($mvfiletmp,$uploadfile);
return $result;
}
}

function rand_string($len, $chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'){ //指定範圍內隨機提取字元
$string = '';
for ($i = 0; $i < $len; $i++){
$pos = rand(0, strlen($chars)-1);
$string .= $chars{$pos};
}
return $string;
}
}
echo '

檔案名稱

檔案類型

檔案大小(KB)

執行結果

';
echo '繼續上傳 返回首頁';
?>

下面還有第三個檔案,就是index.php顯示檔案了.
