本文实例讲述了PHP多文件上传类。分享给大家供大家参考。具体如下：复制代码 代码如下:<?php /*PHP多文件上传类修改：Linvo 2008-2-15*/class more_file_upload{ const FILE_PATH="../upfileclass/uploadfile/"; var $file_type; var $file_type_array; var $file_type_real_array; var $file_type_string; var $file_name; var $file_size; var $file_tmp_name; var $file_error; var $handledate; var $totalsize=0; function __construct($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("/", "image/gif", "image/jpg", "image/jpeg", "image/pjpeg", "image/png"); $this->$file_type_real_array = array(0.1, "jpg"=>74707370, "gif"=>7173, "bmp"=>6677, "png"=>807871); $this->show_execute_message($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; $this->$totalsize = 0;} function show_execute_message($smfileerror,$smfilename,$smfiletype,$smfilesize){if($smfileerror>0){ switch ($smfileerror){ case 1: $smfilemessage="<strong>文件超过服务器的约定大小！</strong>";break; case 2: $smfilemessage ="<strong>文件超过指定的文件大小！</strong>";break; case 3: $smfilemessage="<strong>文件只上传了部分！</strong>";break; case 4: echo "$this->$file_name "."文件上传失败！<br/>";break; } self::__destruct();}else{ $smfiletypeflag = array_search($smfiletype,$this->$file_type_array); //进行真实格式验证if($smfiletypeflag != false){$file = fopen($this->$file_tmp_name, "rb");$bin = fread(file, 10);fclose($file);$strInfo = @unpack("c10chars", $bin);$typeCode = intval($strInfo["chars1"].$strInfo["chars2"]);$smfiletypeflag = array_search($typeCode, $this->$file_type_real_array);if($smfiletypeflag == false){ //判断是否是png图片$typeCode = intval($strInfo["chars2"].$strInfo["chars3"].$strInfo["chars4"]);$smfiletypeflag = array_search($typeCode, $this->$file_type_real_array);if($smfiletypeflag == false){ //判断是否是jpg图片$$typeCode = intval($strInfo["chars7"].$strInfo["chars8"].$strInfo["chars9"].$strInfo["chars10"]);$smfiletypeflag = array_search($typeCode, $this->$file_type_real_array);}}} if($smfiletypeflag == false){$smfilemessage="<strong>文件类型不对，请核实！</strong>";self::__destruct();}else{$resflag = $$this->move_file($$this->$file_tmp_name,$this->$file_name);if ($resflag == 1){$smfilemessage = "文件上传成功！";$this->totalsize += intval($smfilesize);self::__destruct();}else{$smfilemessage = "<strong>文件上传失败！</strong>";self::__destruct();}}} $$smfilesizeformat = $this->size_BKM($smfilesize);echo "<tr><td align="left" >".$smfilename."</td><td align="center" >".$smfiletype."</td><td align="center" >".$smfilesizeformat."</td><td align="center" >".smfilemessage."</td></tr>";} function move_file($mvfiletmp,$mvfilename){ //移动文件$mvfilenamearr = explode(".",basename($mvfilename));$mvfilenamearr[0] = $this->rand_string();$mvfilename = implode(".",$mvfilenamearr); if (is_uploaded_file($mvfiletmp)){$uploadfile = self::FILE_PATH."$mvfilename";$result = move_uploaded_file($mvfiletmp,$uploadfile);return $result;}} function rand_string(){$string = md5(uniqid(rand().microtime()));return $string;} function size_BKM($size){ // B/KB/MB单位转换if($size < 1024){$size_BKM = (string)$size .

希望本文所述对大家的php程序设计有所帮助。
