PHP implements batch upload function for specified suffix files

This article mainly introduces PHP to implement the batch upload function for specified suffix files. Interested friends can refer to it. I hope it will be helpful to everyone.

The example of this article describes the method of uploading multiple files in PHP, as follows:

<?php
define(&#39;ROOT&#39;,&#39;D:/Program Files/www/test/&#39;);
class Files_Tool{
 protected static $allowExt=array(&#39;.jpg&#39;,&#39;.jpeg&#39;,&#39;.png&#39;,&#39;.gif&#39;,&#39;.bmp&#39;,&#39;.svg&#39;,&#39;.chm&#39;,&#39;.pdf&#39;,&#39;.zip&#39;,&#39;.rar&#39;,&#39;.tar&#39;,&#39;.gz&#39;,&#39;.bzip2&#39;,&#39;.ppt&#39;,&#39;.doc&#39;);
 public  static $wrong=array();
 public  static $path=array();
 protected static $error=array(
   0=>&#39;文件上传失败,没有错误发生,文件上传成功&#39;,
   1=>&#39;文件上传失败,上传的文件超过了 php.ini中upload_max_filesize 选项限制的值&#39;,
   2=>&#39;文件上传失败,上传文件的大小超过了 HTML 表单中 MAX_FILE_SIZE 选项指定的值&#39;,
   3=>&#39;文件上传失败,文件只有部分被上传&#39;,
   4=>&#39;文件上传失败,没有文件被上传&#39;,
   5=>&#39;文件上传失败,未允许的后缀&#39;,
   6=>&#39;文件上传失败,找不到临时文件夹.PHP 4.3.10 和 PHP 5.0.3 引进&#39;,
   7=>&#39;文件上传失败,文件写入失败.PHP 5.1.0 引进&#39;,
   8=>&#39;文件上传失败,未接收到表单域的NAME&#39;,
   9=>&#39;文件上传失败,,错误未知&#39;
   );
  public static function upload($name){
   //检测是否接收到表单域的NAME
   if(!isset($_FILES[$name])){
    self::$wrong[]=8;
    return false;
   }
   //3维数组简化成2维数组
   $files=array_shift($_FILES);
   //获取后缀
   $files=self::get_Ext($files);
   //处理文件次数
   $n=count($files[&#39;name&#39;]);
   for($i=0;$i<$n;$i++){
    //查看当前文件是否有错误信息,有则跳过当前文件,处理下个文件
    if($files[&#39;error&#39;][$i]!=0){        
    self::$wrong[$i+1]=$files[&#39;error&#39;][$i];
    continue;
    }
    //查看当前文件的后缀,是否允许,如果不允许,跳过当前文件
    if(!in_array($files[&#39;name&#39;][$i],self::$allowExt)){
     self::$wrong[$i+1]=5;
     continue;
    }
    //路径
    $dir=self::time_Dir();
    //文件名
    $name=self::rand_Name();
    //后缀
    $ext=$files[&#39;name&#39;][$i];
    //文件位置
    $path=$dir.$name.$ext;
    //移动临时文件,如果失败,跳过当前文件
    if(!move_uploaded_file($files[&#39;tmp_name&#39;][$i],$path)){
    self::$wrong[$i]=9;
    continue;
    }
    //存入路径
    self::$path[$i+1]=strtr($path,array(ROOT=>&#39;&#39;));
   }
   return self::$path;
  }
  //获取后缀的方法
  protected static function get_Ext($arr){
    if(!is_array($arr) || !isset($arr[&#39;name&#39;])){return false;}
    foreach($arr[&#39;name&#39;] as $k=>$v){
    $arr[&#39;name&#39;][$k]=strtolower(strrchr($v,&#39;.&#39;));
    }
    return $arr;
  }
  //以日期生成路径
  protected static function time_Dir(){
   $dir=ROOT.&#39;Data/images/&#39;.date(&#39;Y/m/d/&#39;,time());
   if(!is_dir($dir)){
    mkdir($dir,0777,true);
   }
   return $dir;
  }
  //生成随机文件名
  protected static function rand_Name(){
   $str=str_shuffle(&#39;1234567890qwertyuiopasdfghjklzxcvbnm&#39;);
   $str=substr($str,0,6);
   return $str;
  }
  //错误接口
  public static function errors(){
   foreach(self::$wrong as $k=>$v){
    self::$wrong[$k]=&#39;第&#39;.$k.&#39;个&#39;.self::$error[$k];
  }
  return self::$wrong;
  }
}
