PHP实现多图片上传类实例_PHP

本文所述为一个实用的PHP多图片文件上传类，其支持gif、jpg、jpeg、pjpeg、png格式的多图片上传功能，类中还可限制图片类型、上传图片的大小、设置上传目录、一些提交判断等功能。此外该类并不局限于图片的上传，也可以上传TXT/RAR等文件类型，只是需要对代码进行一下修改，感兴趣的读者可以自己尝试一下。

php多图片上传类完整功能代码如下：

 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;    <em style="color:transparent">本@文来源[email protected]搞@^&代*@码网(</em><q>搞代gaodaima码</q>  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;    self :: 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){          $smfilemessage = '文件上传成功！';          self :: totalsize += intval($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 . " B";      }    elseif(size 

读者可以将上述代码复制到PHP文件中，并保存文件名为：more_upload_file.class.php，在使用时include该文件即可。
