本文實例講述了PHP實現的多文件上傳類及用法。分享給大家供大家參考，具體如下：
1、upFiles.css.php 文件
<?phpclass UploadFiles{ private $maxsize = '1000000'; //允許上傳文件最大長度 private $allowtype = array('jpg','png','gif','jpeg');//允許上傳文件類型 private $israndfile = true;//是否隨機文件名 private $filepath;//上傳路徑 private $originName;//上傳的源文件 private $tmpfileName;//臨時文件名 private $newfileName;//新文件名 private $fileSize;//文件大小 private $fileType;//文件類型 private $errorNum = 0;//錯誤號 private $errorMessg = array();//錯誤消息 //對成員初始化 function __construct($options = array()){ foreach($options as $key=>$val){ $key = strtolower($key); //查看傳進來的數組里下標是否與成員屬性相同 //print_r(array_keys(get_class_vars(get_class($this)))); if(!in_array($key,array_keys(get_class_vars(get_class($this))))){ continue; }else{ $this->setOption($key,$val); } } } private function setOption($key,$val){ $this->$key = $val; //echo $this->errorNum."<br>"; } //檢查文件上傳路徑 private function checkfilePath(){ //echo $this->filepath; if(empty($this->filepath)){ $this->setOption('errorNum',"-5"); return false; } if(!file_exists($this->filepath) || !is_writable($this->filepath)){ if(!@mkdir($this->filepath,0755)){ $this->setOption('errorNum','-4'); return false; } } return true; } //獲取錯誤信息 private function getError(){ $str = "上傳文件{$this->originName}出錯---"; switch($this->errorNum){ case 4; $str .= "沒有文件被上傳";break; case 3; $str .= "文件只被部分上傳";break; case 2; $str .= "超過文件表單允許大小";break; case 1; $str .= "超過php.ini中允許大小";break; case -1; $str .= "未允許的類型";break; case -2; $str .= "文件過大，不能超過".$this->maxsize."個字節";break; case -3; $str .= "上傳失敗";break; case -4; $str .= "建立文件上傳目錄失敗";break; case -5; $str .= "必須指定上傳路徑";break; default; $str .= "未知錯誤"; } return $str."<br>"; } //檢查文件類型 private function checkfileType(){ //echo $this->fileType; if(!in_array(strtolower($this->fileType),$this->allowtype)){ $this->setOption('errorNum','-1'); return false; }else{ return true; } } //檢查文件大小 private function checkfileSize(){ if($this->fileSize > $this->maxsize){ $this->setOption('errorNum','-2'); return false; }else{ return true; } } //處理隨機文件名稱 private function prorandFile(){ $ch = $this->israndfile; if($ch == 'true'){ return true; }else{ return false; } } // private function setFiles($name="",$tmp_name="",$size="",$error=""){ //檢查上傳路徑 if(!$this->checkfilePath()){ //$this->errorMessg = $this->getError(); return false; } //echo $error."<br>"; if($error){ $this->setOption('errorNum',$error); return false; } $arrstr = explode('.',$name); $type = end($arrstr); $this->setOption('originName',$name); $this->setOption('fileSize',$size); $this->setOption('fileType',$type); $this->setOption('tmpfileName',$tmp_name); return true; } //檢查是否有文件上傳 function checkFile($formname){ if(!@$_FILES[$formname]){ $this->setOption('errorNum',4); return false; }else{ return true; } } //上傳文件 function uploadeFile($formname){ if(!$this->checkFile($formname)){ $this->errorMessg = $this->getError(); return false; } $return = true; $name = @$_FILES[$formname]['name']; $tmp_name = @$_FILES[$formname]['tmp_name']; $size = @$_FILES[$formname]['size']; $error = @$_FILES[$formname]['error']; //$type = $_FILES[$formname]['type']; if(is_array($name)){ $errors = array(); for($i=0; $i<count($name); $i++){ if($this->setFiles($name[$i],$tmp_name[$i],$size[$i],$error[$i])){ if(!$this->checkfileSize() || !$this->checkfileType()){ $errors[] = $this->getError(); $return = false; } }else{ $errors[] = $this->getError(); $return = false; } if(!$return) $this->setFiles(); } if($return){ $newfileN = array(); for($i=0; $i<count($name); $i++){ if($this->setFiles($name[$i],$tmp_name[$i],$size[$i],$error[$i])){ if(!$this->copyFile()){ $errors[] = $this->getError(); $return = false; }else{ $newfileN[] = $this->newfileName; } } $this->newfileName = $newfileN; } } //print_r($errors); $this->errorMessg = $errors; //echo $errors; return $return; }else{ if($this->setFiles($name,$tmp_name,$size,$error)){ $return = true; if($error) var_dump($error); if($this->checkfileSize() && $this->checkfileType()){ }else{ $return = false; } }else{ $return = false; } if(!$return){ $this->errorMessg = $this->getError(); } return $return; } } //獲取上傳后的文件名 function getnewFile(){ return $this->newfileName; } //把文件拷貝到指定的路徑 function copyFile(){ $filepath = rtrim($this->filepath,'/')."/"; if(!$this->errorNum){ if($this->prorandFile()){ $this->newfileName = date('Ymdhis').rand(1000,9999).".".$this->fileType; }else{ $this->newfileName = $this->originName; } if(!move_uploaded_file($this->tmpfileName,$filepath.$this->newfileName)){ $this->setOption('errorNum',-3); return false; }else{ return true; } }else{ return false; } } //上傳錯誤后返回的消息 function gteerror(){ $err = $this->errorMessg; return $err; } }?> 2、使用方法
uploade.php 文件：
<?php//print_r($_FILES['spic']);header('Content-Type:text/html;charset=utf-8');//if(@$_FILES['spic'])echo "ddddddddd";;include('upFiles.css.php');$upfile = new UploadFiles(array('filepath'=>'./upload','allowtype'=>array('php','bmp','gif','jpg','png'),'israndfile'=>true,'maxsize'=>'1000000'));if($upfile ->uploadeFile('spic')){ $arrfile = $upfile ->getnewFile(); foreach($arrfile as $v){ echo $v,"<br/>"; } echo "上傳成功！";}else{ $err = $upfile ->gteerror(); if(is_array($err)){ foreach($err as $v1){ echo $v1,"<br/>"; } }else{ echo $err; } //var_dump($err);}//var_dump($upfile);?> HTML 文件：
