本文实例讲述了PHP实现的多文件上传类及用法。分享给大家供大家参考，具体如下：

1、upFiles.css.php 文件

<?php class UploadFiles{ private $maxsize = '1000000'; //允许上传文件最大长度 private $allowtype = array('jpg','png','gif','jpeg');//允许上传文件类型 private $israndfile = true;//是否随机文件名 private $filepath;//上传路径 private $originName;//上传的源文件 private $tmpfileName;//临时文件名 private $newfileName;//新文件名 private $fileSize;//文件大小 private $fileType;//文件类型 private $errorNum = 0;//错误号 private $errorMessg = array();//错误消息 //对成员初始化 function __construct($options = array()){ foreach($options as $key=>$val){ $key = strtolower($key); //查看传进来的数组里下标是否与成员属性相同 //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>"; } //检查文件上传路径 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; } //获取错误信息 private function getError(){ $str = "上传文件{$this->originName}出错---"; switch($this->errorNum){ case 4; $str .= "没有文件被上传";break; case 3; $str .= "文件只被部分上传";break; case 2; $str .= "超过文件表单允许大小";break; case 1; $str .= "超过php.ini中允许大小";break; case -1; $str .= "未允许的类型";break; case -2; $str .= "文件过大，不能超过".$this->maxsize."个字节";break; case -3; $str .= "上传失败";break; case -4; $str .= "建立文件上传目录失败";break; case -5; $str .= "必须指定上传路径";break; default; $str .= "未知错误"; } return $str."<br>"; } //检查文件类型 private function checkfileType(){ //echo $this->fileType; if(!in_array(strtolower($this->fileType),$this->allowtype)){ $this->setOption('errorNum','-1'); return false; }else{ return true; } } //检查文件大小 private function checkfileSize(){ if($this->fileSize > $this->maxsize){ $this->setOption('errorNum','-2'); return false; }else{ return true; } } //处理随机文件名称 private function prorandFile(){ $ch = $this->israndfile; if($ch == 'true'){ return true; }else{ return false; } } // private function setFiles($name="",$tmp_name="",$size="",$error=""){ //检查上传路径 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; } //检查是否有文件上传 function checkFile($formname){ if(!@$_FILES[$formname]){ $this->setOption('errorNum',4); return false; }else{ return true; } } //上传文件 function uploadeFile($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; } } //获取上传后的文件名 function getnewFile(){ return $this->newfileName; } //把文件拷贝到指定的路径 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; } } //上传错误后返回的消息 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 "上传成功！"; }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：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>无标题文档</title> <script type="text/javascript"> function Check(){ //alert('dddd'); for(i=1; i<9; i++){ if(document.getElementById('v'+i).value == ''){ document.getElementById('v'+i).name = 'uu'; } } } </script> </head> <body> <form name="upfile" action="uploade.php" method="post" enctype="multipart/form-data"> <input type="file" name="spic[]" id="v1" /><br/> <input type="file" name="spic[]" id="v2" /><br/> <input type="file" name="spic[]" id="v3" /><br/> <input type="file" name="spic[]" id="v4" /><br/> <input type="file" name="spic[]" id="v5" /><br/> <input type="file" name="spic[]" id="v6" /><br/> <input type="file" name="spic[]" id="v7" /><br/> <input type="file" name="spic[]" id="v8" /><br/> <input type="submit" name="sub" value="提交" /> <input type="reset" name="res" value="重填" /> </form> </body> </html>
