Multiple file upload classes and usage examples implemented in PHP,

This article describes the multi-file upload class and usage examples implemented in PHP. Share it with everyone for your reference, the details are as follows:

1. upFiles.css.php file

<&#63;php
class 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(shù)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);
  }

 //檢查文件上傳路徑

 }
 //上傳錯誤后返回的消息
 function gteerror(){

 }
 }

2. How to use

uploade.php file:

<&#63;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);
&#63;>
