PHP实现的多文件上传类及用法示例

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;
     }
     }

      return false;
     }else{
      return true;
     }
     }
     //处理随机文件名称
     private function prorandFile(){

     if($ch == 'true'){
      return true;
     }else{

     }
     }

     $this->setOption('fileSize',$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);

     function getnewFile(){

     function copyFile(){

     }
     }
     //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" onclick="return Check()" />
    <input type="reset" name="res" value="重填" />
    </form>
    </body>
    </html>
