How to implement multiple file uploads in PHP

The example in this article describes how to implement multiple file uploads in PHP. Share it with everyone for your reference. The specific implementation method is as follows:

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 $error=array(
 0=> ;'File upload failed, no error occurred, file upload was successful',
 1=>'File upload failed, the uploaded file exceeded the value limited by the upload_max_filesize option in php.ini',
 2=>'File upload failed ,The size of the uploaded file exceeds the value specified by the MAX_FILE_SIZE option in the HTML form',
 3=>'File upload failed, only part of the file was uploaded',
 4=>'File upload failed, no file was uploaded',
 5=>'File upload failed, suffix not allowed',
 6=>'File upload failed, temporary folder not found. Introduced in PHP 4.3.10 and PHP 5.0.3',
 7=> 'File upload failed, file writing failed. Introduced in PHP 5.1.0',
 8=>'File upload failed, the name of the form field was not received',
 9=>'File upload failed,,error unknown'
 );
 public static function upload($name){
 //Check whether the NAME of the form field is received
 if(!isset($_FILES[$name])){
 self::$wrong[]=8;
 return false;
 }
 //3D array is simplified into 2D array
 $files=array_shift($_FILES);
 //Get the suffix
 $files=self::get_Ext($files);
 //Process files Number of times
 $n=count($files['name']);
 for($i=0;$i<$n;$i++){
 //Check whether the current file has an error message, if so, skip the current one file, process the next file
 if($files['error'][$i]!=0){
 self::$wrong[$i+1]=$files['error'][$i];
 continue;
 }
 //Check the suffix of the current file, whether it is allowed, if not, skip the current file
 if(!in_array($files['name'][$i],self::$allowExt)) {
 self::$wrong[$i+1]=5;
 continue;
 }
 //Path
 $dir=self::time_Dir();
 //File name
 $name=self::rand_Name( );
 //Suffix
 $ext=$files['name'][$i];
 //File location
 $path=$dir.$name.$ext;
 //Move temporary files, if failed, Skip the current file
 if(!move_uploaded_file($files['tmp_name'][$i],$path)){
 self::$wrong[$i]=9;
 continue;
 }
 //Save Path
 self::$path[$i+1]=strtr($path,array(ROOT=>''));
 }
 return self::$path;
 }
 //Method to get suffix
 protected static function get_Ext($arr){
 if(!is_array($arr) || !isset($arr['name'])){return false;}
 foreach($arr['name'] as $k =>$v){
 $arr['name'][$k]=strtolower(strrchr($v,'.'));
 }
 return $arr;
 }
 //Generate path with date
 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 a random file name
 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[$k]='th'.$k.'th'.self::$error[$k];
 }
 return self::$wrong;
 }
}
