PHP implementation of multiple file upload method _php skills

This article describes the PHP implementation of multiple file upload method. Share to everyone for your reference. The implementation method is as follows:

<?php define (' ROOT ', ' D:/program files/www/test/'); Class files_tool{protected static $allowExt =array ('. jpg ', '. jpeg ', '. png ', '. gif ', '. bmp ', '. svg ', '. chm ', '. pdf ', '. Zip '
 , '. rar ', '. Tar ', '. Gz ', '. bzip2 ', '. ppt ', '. Doc ';
 public static $wrong =array ();
 public static $path =array (); protected static $error =array (0=> ' file upload failed, no error occurred, file upload success ', 1=> ' file upload failed, upload file over php.ini
  Option limit value ', 2=> ' file upload failed, upload file size exceeds the value specified in HTML form max_file_size option ', 3=> ' file upload failed, file only partially uploaded ', 4=> ' file upload failed, no file uploaded ', 5=> ' File upload failed, disallowed suffix ', 6=> ' file upload failed, temp folder not found. PHP 4.3.10 and PHP 5.0.3 introduced ', 7=> ' file upload failed, file write failed.
  PHP 5.1.0 introduced ', 8=> ' file upload failed, did not receive the form field name ', 9=> ' file upload failed, error unknown ');
    public static function upload ($name) {//detects whether a form field is received the name if (!isset ($_files[$name))) {self:: $wrong []=8;
   return false;
   The//3 dimension array is simplified into a 2-D array $files =array_shift ($_files);
   Gets the suffix $files =self::get_ext ($files);
   Number of processing files $n =count ($files [' name ']); for ($i =0; $i < $n; $i + +) {//view current fileIf there is an error message, skip the current file and process the next file if ($files [' Error '] [$i]!=0) {self:: $wrong [$i +1]= $files [' Error '] [$i];
    Continue
     }//View the suffix of the current file, allow, if not allowed, skip the current file if (!in_array ($files [' name '] [$i],self:: $allowExt)) {self:: $wrong [$i +1]=5;
    Continue
    }//Path $dir =self::time_dir ();
    FileName $name =self::rand_name ();
    suffix $ext = $files [' name '] [$i];
    File location $path = $dir. $name. $ext;
    Moves the temporary file, if it fails, skips the current file if (!move_uploaded_file ($files [' tmp_name '] [$i], $path)) {self:: $wrong [$i]=9;
    Continue
   //Deposit Path Self:: $path [$i +1]=strtr ($path, Array (root=> '));
  Return self:: $path;
    }//Get suffix protected static function Get_ext ($arr) {if!is_array ($arr) | | |!isset ($arr [' name '])) {return false;}
    foreach ($arr [' name '] as $k => $v) {$arr [' name '] [$k]=strtolower (STRRCHR ($v, '. '));
  return $arr;
   ///Date build path protected static function Time_dir () {$dir =root. ' data/images/'. Date (' y/m/d/', Time ()); if (!is_dir ($dir)){mkdir ($dir, 0777,true);
  return $dir;
   //Generate random filename protected static function Rand_name () {$str =str_shuffle (' 1234567890qwertyuiopasdfghjklzxcvbnm ');
   $str =substr ($str, 0,6);
  return $str; }//Error interface public static function errors () {foreach (self:: $wrong as $k => $v) {self:: $wrong [$k]= ', $k. Self:
  : $error [$k];
  Return self:: $wrong;

 }
