php多文件上传代码二_PHP教程

fileclass.php文件代码如下:

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){

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

}

function show_execute_message($smfileerror,$smfilename,$smfiletype,$smfilesize){

switch ($smfileerror){
case 1: $smfilemessage='文件超过服务器的约定大小！';break;
case 2: $smfilemessage='文件超过指定的文件大小！';break;
case 3: $smfilemessage='文件只上传了部分！';break;
case 4: echo "$this->file_name ".'文件上传失败！
';break;
}
self::__destruct();
}else{
$smfiletypeflag=array_search($smfiletype,$this->file_type_array);
if($smfiletypeflag == false){
$smfilemessage='文件类型不对，请核实！';
self::__destruct();
}else{
$resflag=$this->move_file($this->file_tmp_name,$this->file_name);
if ($resflag == 1){
$smfilemessage='文件上传成功！';
self::$totalsize+=intval($smfilesize);
self::__destruct();
}else{

}
}
}

}

function move_file($mvfiletmp,$mvfilename){ //移动文件

$mvtime=mktime();
$mvfilenamearr[0]=$this->rand_string(10)."$mvtime";

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

function rand_string($len, $chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'){ //指定范围内随机提取字符
$string = '';
for ($i = 0; $i $pos = rand(0, strlen($chars)-1);
$string .= $chars{$pos};
}
return $string;
}
}
echo '

echo '

for ($i=0;$i $filename[$i]=$_FILES['userfile']['name'][$i];

$filetemp=new more_file_upload("$filename[$i]","$fileerror[$i]","$filesize[$i]","$filetmpname[$i]","$filetype[$i]");
}
echo '

文件类型

文件大小(KB)

执行结果

';
echo '继续上传 返回首页';
?>

下面还有第三个文件,就是index.php显示文件了.
